Introduction
Scope of the Manual
This instruction manual provides installation, maintenance and parts ordering information for the Types OS2 and OSD2 slam-shut devices. The Type OS2 slam-shut device is used on Type OSE with NPS 1 through 6 / DN 25 through 150 body sizes, while Type OSD2 is used on NPS 8 and 10 / DN 200 and 250 body sizes.
For more information on Type OS2 installed on other regulators such as Types EZHOSX, EZHSO-OSX, EZLOSX and EZROSX, refer to the instruction manuals of these products.
Description
Slam-shut devices are used to totally and rapidly cut off gas flow when the inlet and/or outlet pressure in the system either exceeds or drops below the setpoints. The Type OSE consists of a valve, mechanism box (BM1 or BM2) and either one or two modular sensing elements called manometric devices (Type BMS1 or BMS2) (see Figure 2). All information for the Type OSE (which includes a Type OS2 slam-shut device and a Type E valve body) is contained in this Instruction Manual.

Type EZROSX (see Figure 1) is a combination of the Type EZR regulator and the Type OS2 slam-shut device. For installation, maintenance and parts information on the Type EZR portion, refer to Type EZR Instruction Manual D102600X012.
Type EZHOSX is a combination of the Type EZH regulator and the Type OS2 slam-shut device. Details related to installation, maintenance and parts information are listed in the Type EZH Instruction Manual D103077X012.
Type EZLOSX is a combination of the Type EZL regulator and the Type OS2 slam-shut device. Details related to installation, maintenance and parts information are listed in the Type EZL Instruction Manual D103091X012.
Incorporated in the Type OS2 (up to NPS 6 / DN 150 body size) valve plug is an automatic internal bypass valve mechanism, which balances pressures on both sides of the plug when resetting. Type OSD2 will be used for NPS 8 and 10 / DN 200 and 250 Type OSE slam-shut valves; in this case the bypass is not internal but external.
The Types OS2 and OSD2 slam-shut devices can be used for all pressure ranges from 4.02 in. w.c. to 1470 psig / 10 mbar to 101 bar by simply replacing the manometric sensing device. The Type OS2 can be configured for OverPressure ShutOff (OPSO), UnderPressure ShutOff (UPSO), OverPressure Shutoff and UnderPressure ShutOff (OPSO/UPSO), manual shutoff or remote shutoff.
Mechanism Box (BM1 or BM2)
The mechanism box (BM1 or BM2, see Figure 2) is designed to close the slam-shut valve. The detection of pressure variances is sensed by a double-stage trip mechanism (see Figure 7). The first stage is the detection stage and will only trip when the system pressure reaches the set pressure of the manometric sensing device. The second stage is the power stage and once tripped by the first stage, the closing spring causes the valve plug to slam-shut and remain closed until the valve is manually reset. If there are any inlet pressure variances or vibrations subjected to the second stage components, they are not transmitted to the first stage trip mechanism. This unique double-stage trip mechanism virtually eliminates nuisance tripping commonly found in other shutoff devices.

Manometric Sensing Device (Type BMS1 or BMS2) (See Figure 2)
Pressure from the system is sensed through control lines into the manometric sensing device (Type BMS1, BMS2 or Types BMS1 and BMS2). Depending on the configuration, the Type BMS1 or BMS2 will transmit these pressure fluctuations to the mechanism box. If these fluctuations reach the setpoint of the manometric sensing device (Type BMS1 or BMS2), the device will activate the tripping mechanism in the mechanism box (Type BM1 or BM2) and cause the valve to slam-shut.
Remote Shutoff
Remote Tripping is accomplished using a 3-way solenoid valve installed in the control line of a Type BMS1 or BMS2 manometric device configured for underpressure protection (UPSO) or overpressure and underpressure protection (OPSO/UPSO). When de-energized, the solenoid valve allows the Type BMS manometric device to monitor the controlled pressure as if the solenoid valve was not present. When energized, the solenoid valve will be repositioned to connect the Type BMS manometric device to atmospheric pressure tripping the underpressure protection slam-shut setting.
*For further instructions on Types EZR, EZH and EZL, refer to the corresponding instruction manual of these products.
Principle of Operation* (See Figure 3)
The Type OSE slam-shut valve and the Type OS2 slam-shut device used on Type EZHOSX, EZROSX or EZLOSX provides overpressure and/or underpressure protection by shutting off the flow to the downstream system. The slam-shut valve is typically installed upstream of a pressure reducing regulator as shown in Figure 4.
Pressure is registered on one side of the diaphragm, piston or bellows and is opposed by the setpoint control spring of the manometric sensing device. The Type OS2 slam-shut device tripping pressure is determined by the setting of the control spring.
Overpressure: when the sensed pressure increases above the setpoint, the pressure on top of the diaphragm overcomes the spring setting and moves the manometric device stem.
Underpressure: when the sensed pressure decreases below the setpoint, the control spring pressure below the diaphragm overcomes the downstream pressure and pushes the diaphragm which moves the manometric device stem.
When the sensed pressure rises above the set pressure (or drops below the set pressure) the manometric device senses the pressure change and triggers the detection stage which

activates the second stage, releasing the slam-shut valve plug. A tight and total shutoff is ensured by the plug seal O-ring closing on the orifice and is helped by the “dash pot” effect between the bonnet skirt and the valve plug. A “dash pot” effect occurs when the valve plug closes by having both the closing spring and the inlet pressure pushing on top of the valve plug. This is accomplished by ports around the skirt of the bonnet allowing inlet pressure above the valve plug.

conditions exceed any ratings of the adjacent piping or piping connections. To avoid this, install the slam-shut valve where service conditions are within unit capabilities and applicable codes, regulations or standards. Additionally, physical damage to the slam-shut valve could break the mechanism box off the main valve, causing personal injury and property damage due to escaping gas. To avoid such injury or damage, install the unit in a safe location.
Installation, operation and maintenance procedures performed by unqualified personnel may result in improper adjustment and unsafe operation. Either condition may result in equipment damage or personal injury. Use qualified personnel when installing, operating and maintaining the unit.

Clean out all pipelines before installation and check to be sure the valve has not been damaged or collected foreign material during shipment. Use suitable line gaskets and good bolting practices with a flanged body. The Type OSE must be installed in a horizontal position with the mechanism box above the body (see Figure 2). The Types EZHOSX, EZROSX and EZLOSX are installed with the mechanism box typically below the pipe. Type OS2 slam-shut device can also be installed in a pit that is subject to flooding by venting the mechanism box above the maximum possible flood level. When used below ground, the vent must be relocated (piped) to keep the mechanism box from collecting moisture and/or other foreign material. Install obstruction-free tubing or piping into the 1/4 NPT vent tapping. Provide protection on the relocated vent by installing a screened vent cap into the end of the vent pipe.
Type OS2 can be used along with a token relief valve to minimize unnecessary shutoff. The relief valve is set to open before the Type OS2 slam-shut device activates. This arrangement allows the relief valve to handle minor overpressure problems such as gas thermal expansion or seat leakage due to dirt moving through the system which may move out of the regulator during the next operating cycle. The slam-shut device does activate if the regulator has a major malfunction with excessive gas flow that exceeds the token relief capacity.
The manometric device requires an external sensing line which should be tapped into a straight run of pipe 8 to 10 pipe diameters downstream or upstream of the slam-shut device. If impossible to comply with this recommendation due to the pipe arrangement, it may be better to position the sensing line tap nearer the regulator or slam-shut outlet rather than downstream of a block valve. Do not position the tap near any elbow, swage or nipple which might cause turbulence. It is recommended to install an isolation valve and a vent valve on the sensing line, which can be useful for tripping and verifications.
Startup*
WARNING
!
To avoid personal injury or property damage due to explosion or damage to regulator or downstream components during startup, release downstream pressure to prevent an overpressure condition on the diaphragm of the regulator. In order to avoid an overpressure condition and possible equipment damage, pressure gauges should always be used to monitor pressures during startup.
These startup procedures are for the Type OSE/OS2 only.
1. Make sure the upstream and downstream shutoff valves are closed.
2. Slowly open the upstream shutoff valve.
3. For NPS 8 and 10 / DN 200 and 250 body sizes, slowly open the bypass valve.
4. The slam-shut valve is shipped with the slam-shut device in the tripped position. To reset the slam-shut, follow the procedure under Resetting the Trip Mechanism in the Adjustment section.
5. For NPS 8 and 10 / DN 200 and 250 body sizes, close the slam-shut valve bypass.
6. Slowly open the downstream shutoff valve.
7. Check all connections for leaks.
8. Adjust the slam-shut pressure setting by following the appropriate procedures in the Adjustment section.

6. Verify that the trip pressure is equal to the desired pressure setting by increasing pressure to the Type BMS2, resetting the detection stage and then reducing pressure to the Type BMS2 until the detection stage trips. Adjust trip pressure setting if necessary.
Resetting the Trip Mechanism
Resetting of the Type OS2 slam-shut device is done manually and, for NPS 8 and 10 / DN 200 and 250 body sizes, with the bypass valve open. After the Type OS2 has closed, it must be manually reset before it can be placed back in service. Before resetting the Type OS2, check for and correct the reason for the overpressure/underpressure condition. For the following procedures, see Figures 7 and 8.
Note
To reset the detection stage, the pressure in the manometric sensing device must be below the overpressure trip point and/ or above the underpressure trip point. Otherwise the detection stage cannot be reset.
Note
Because the Type OS2 mounted on the Type EZHOSX, EZROSX or EZLOSX is turned 180°, the following directions apply to the Type OSE only, however, the reset procedure for the Type EZHOSX, EZROSX or EZLOSX is the same. When a specific direction is given (i.e. top left), the Type EZHOSX, EZROSX or EZLOSX direction will be reversed (i.e. bottom right).
To reset the Type OS2, close the upstream block valve. Open the front cover of the mechanism box.
Detection Stage (First Stage)
The reset pin with white dot is at the top center location of the mechanism box, see Figure 8. Push this pin up and to the right (Type OSE only, see note above). This action will lock in the detection stage (see step A in Figure 7).
When movement is started on the stem, the internal bypass in sizes from NPS 1 through 6 / DN 25 through 150 will open and equalize the pressure on each side of the valve plug before the valve plug can be moved off the seat. For NPS 8 and 10 / DN 200 and 250, external bypass valve should be opened. Continue turning the reset tool.
CAUTION
Wait for the pressure on each side of the valve plug to equalize before proceeding to the following steps. Never use an extension with the reset tool when resetting the second stage. Failure to do so may result in equipment damage.
This action will raise the valve plug, compress the closing spring and latch the second stage (power stage) mechanism. Replace the reset tool on its holder and replace the cover. Slowly open the upstream block valve.
Shutdown*
WARNING
!
To avoid personal injury or property damage due to explosion or damage to shutoff device, regulator or downstream components during shutdown, release downstream pressure to prevent an overpressure condition on the regulator diaphragm.
Installation arrangements may vary, but in any installation it is important that the valves be opened or closed slowly. The steps below apply to the typical installation.
1. Slowly close the downstream shutoff valve.
2. Slowly close the upstream shutoff valve.
3. Slowly open the vent valves downstream of the slam-shut valve.
4. Slowly open the vent valves upstream of the slam-shut valve.
North America Only
Power Stage (Second Stage)
Note
The reset tool is keyed and will only fit on the second stage releasing shaft in one orientation. Be sure the tool securely fits onto the shaft before turning.
To reset the power stage, use the square reset tool located on the lower left corner of the mechanism box. Place the square end of the tool on the second stage releasing shaft at the center of the box and slowly rotate clockwise (see step B in Figure 7).
*For further instructions on Types EZR, EZH and EZL, refer to the corresponding instruction manual of these products.

Disassembly for NPS 1 through 6 / DN 25 through 150 Body Sizes (Refer to Figure 14)
WARNING
!
Avoid personal injury or damage to property from sudden release of pressure or uncontrolled gas or other process fluid. Before disassembling, carefully relieve all pressures. Use gauges to monitor inlet and outlet pressures while releasing these pressures.
Note
The only parts that are replaceable on the Type OS2 are the equalizer bypass component, manometric sensing device (Types BMS1 and BMS2) and the sealing components. The seat ring on the Type OSE is pressed into the body and is not field removable.
Note
The position of the travel stop (Figure 13) depends on the Type of assembly and body size. The travel stop must be in the B position (Figure 13) for NPS 1 and 2 / DN 25 and 50 body sizes. For all other body sizes, the travel stop must be in the C position (Figure 13).
The cover is held on by one screw which can be unscrewed manually or by using a socket (maximum recommended
torqueis1.8ft-lbs/2.4N•m).
1. Open the mechanism cover and replace the cover screw O-ring by removing the circlip.
CAUTION
Trip the mechanism if it is not already released by moving Pin D1 (see Figure 7) to remove as much spring tension on the stem as possible.
2. Trip the mechanism by carefully turning the tripping plate (Pins D1 and D2) clockwise (refer to Figures 5 and 6).
3. Remove the clip (refer to Figure 8). Turn and detach the clevis from the stem by pulling the pin from the sliding clevis.
4. Remove the two cap screws (key 39) holding the mechanism box (key 16) to the bonnet (key 15) and remove the mechanism box.
5. Remove the nuts (key 23, for NPS 4 and 6 / DN 100 and 150 only) or cap screws (key 21) holding the bonnet (key 15) to the body (key 1).
