Product Description
The Type 1290 vapor recovery regulator is a self-contained, pilot-operated regulator system used for vapor recovery of blanketing gas. When blanketing gas pressure inside the vessel rises due to thermal heating or pump-in operations, the Type 1290 regulator senses an increase in vessel pressure and vents excessive internal tank pressure to a vapor recovery storage tank.

Principle of Operation
Note
The Type 1290 vapor recovery regulator serves as a vessel vapor recovery system. The Type 1290 regulator controls vessel blanketing gas pressure when the vessel is being filled with fluid or when
ambient temperature causes the vapor gas to expand. The system monitors the increasing blanket pressure and throttles open to pass excess blanketing gas into a vapor recovery system thus controlling the desired set pressure of the vessel.
The Type 1290 is used as part of the gas blanketing system to control the outflow of blanketing gas under normal conditions and to collect vessel vapors for the vapor recovery system. It is not
an ASME safety relief device. You should provide alternate methods of emergency overpressure protection.
3
Type 1290
The Type 1290 vapor recovery regulator responds to any changes in the blanket gas pressure and throttles open or close to control the flow of the blanket gas out of the vessel. A vacuum source on the outlet of the regulator is necessary to ensure flow of low-pressure blanket gas out of the vessel and into a vapor recovery system. The higher the vacuum source, the more the flow capacity of the vapor recovery regulator.
The pressure of the blanket gas registers under the diaphragm of the pilot. A Type 95H regulator provides a constant loading pressure source to the Type 1098-EGR main valve actuator. When the pilot is closed, the loading pressure fills both sides of the Type 1098 actuator through a fixed restriction.
The Type 1098-EGR main valve spring keeps the main valve plug tightly shut. When the vessel blanket gas pressure reaches the setting of the pilot spring, the pilot diaphragm moves, opening the pilot valve disk and exhausting some of the Type 1098-EGR’s actuator loading pressure through the pilot orifice. This typically happens when the vessel is being filled with liquid.
The small fixed restriction maintains a higher loading pressure on the bottom of the Type 1098 actuator. The pressure differential across the main valve diaphragm moves the diaphragm upward causing the main valve to open which allows the blanket gas to flow out to the vapor recovery system vacuum source, hence controlling the vessel blanket pressure.
When the vessel blanket gas pressure begins to stabilize, the pilot spring throttles and the pilot disk closes. This allows the loading pressure source to fill both sides of the Type 1098 actuator through the fixed restriction. This equalizes the pressure acting on the diaphragm, thus allowing the main valve spring to close the main valve plug.
Installation and Startup
!Warning
Personal injury, equipment damage or leakage due to escaping accumulated gas or bursting of pressure-containing parts may result if this gas blanketing system is overpressured or installed where service conditions could exceed the limits given in the Specifications section and on the appropriate nameplate, or where conditions exceed any ratings of the adjacent piping or piping connections.
To avoid such injury or damage, provide pressure-relieving or pressure-limiting devices (as required by Title 49, Part 192, of the U.S. Code of Federal Regulations, by the National Fuel Gas Code Title 54 of the National Fire Codes of the National Fire Protection Association, or by other applicable codes) to prevent service conditions from exceeding those limits.
Additionally, physical damage to the vapor recovery regulator system could result in personal injury and property damage due to escaping accumulated gas. To avoid such injury and damage, install the vapor recovery system in a safe location.
Note
On the Type EGR main valve, normal pressure drop assists shutoff, therefore, leakage may result during any reverse pressure drop condition.
1.Use qualified personnel when installing, operating and maintaining regulators. Before installing, inspect the main valve, pilot and tubing for any shipment damage or foreign material that may have collected during crating and shipment. Make certain that the body interior is clean and the pipelines are free of foreign material. Apply pipe compound only to the external pipe threads with a threaded body, or use suitable line gaskets and good bolting practices with a flanged body.
Note
The Type 1290 vapor recovery regulator should be installed as shown in Figure 1 so that flow through the Type 1098-EGR main valve matches the flow arrow attached to the valve body.
!Warning
A regulator may vent some gas to the atmosphere. In hazardous or
flammable gas service, vented gas may accumulate and cause personal injury, death or property damage due to fire or explosion. Vent a regulator in hazardous gas service to a remote, safe location away from air intakes or any hazardous location. The vent line or stack opening must be protected against condensation or clogging.
4
Type 1290
2.To keep the pilot spring case vent from being plugged or the spring case from collecting moisture, corrosive chemicals or other foreign material,
point the vent down or otherwise protect it. For proper operation, the Type Y291A pilot should be installed with the spring case barrel pointed down as shown in Figure 1. However, a Type 1290 with a Type Y291AL pilot must be installed with the pilot spring case barrel pointed up. To remotely vent a Type Y291A or Y291AL, remove the vent (key 26) and install obstruction-free tubing or piping into the 1/4 NPT vent tapping. Provide protection on a remote vent by installing a screened vent cap into the remote end of the vent pipe.
3.Refer to Figure 2. Attach a 1/2 NPT upstream pressure control line to the vessel using a straight run of pipe. Connect the other end of the control line to the Type Y291A or Y291AL pilot. Install a
1/2 NPT exhaust line between the pilot and vessel.
4.Run a supply pressure line (see Figure 2) to the Type 95H regulator inlet (use 3/8-inch / 9.5 mm outer diameter tubing or 1/4-inch / 6.4 mm pipe minimum). Type 95H minimum supply pressure should be 10 psig / 0.69 bar higher than the set pressure of the Type 95H regulator.
Pre-startup Considerations
Before beginning the startup procedures in the next section, make sure the conditions below are followed:
• Block valves isolate the regulator.
• Hand valves are closed.
• Gauges may be installed (if required) in place of pipe plugs (key 52, Figure 11).
Note
For proper operation, the Type 95H supply pressure regulator is factory set to the values in the Specifications section.
Startup and Adjustment (Refer to Figure 2)
1.Open valve ‘C’ to supply the energy source. The
Type 95H supply regulator has been preset at the factory according to the control spring in the pilot.
If any field changes have been made, reset the Type 95H outlet pressure. See Table 1 for the correct pressure setting.
2.Open valve ‘D’ (if used). This valve must have a large port area and be fully open.
3.Open valve ‘E’ (if used). This valve must be a full ported valve that will not restrict pressure registration.
Note
When opening valve ‘E’ in step 3, the main valve may go wide-open if the vapor pressure is higher than the pilot setpoint.
4.Slowly open valve ‘A’, introducing pressure into the vapor recovery regulator system.
5.Slowly open valve ‘B’. The regulator will go into immediate operation.
6.The control spring in the Type Y291A will be preset at the factory if setpoint was specified. Otherwise, the factory setpoint is approximately mid-range of the spring. The spring range of the pilot is stamped on the cap of the pilot.
Control spring adjustment may be necessary. To check the setpoint, raise the vessel pressure while observing a pressure gauge (manometer) and the main valve travel indicator to determine whether or not the setpoint is correct. On a Type Y291A, turning the adjusting screw clockwise into the spring case increases the pressure setting. On a Type Y291AL, turning the adjusting screw counterclockwise out of the spring case will increase the pressure setting.
Note
One way to increase the vessel blanketing pressure temporarily is to manually push on the blanketing regulator diaphragm. To push on the diaphragm, remove the spring case
closing cap on the blanketing regulator (Type Y690A, Y692, Y693 or Y291A pilot) and use a screwdriver or rod to temporarily push on the diaphragm assembly and raise the outlet pressure of the blanketing regulator. Release the manual force on the diaphragm and the blanketing regulator will return to its original setpoint.
Shutdown
Installation arrangements may vary but in any installation, it is important that the upstream block valve should be closed first and that the upstream valves be opened or closed slowly.

Type 1290
Maintenance
Regulator parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement of parts depends upon the severity of service conditions or the requirements of local, state and federal regulations. Due to the
care Regulator Technologies takes in meeting all manufacturing requirements (heat treating, dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Regulator Technologies.
The stem O-rings on the Type 1098 actuator can be lubricated annually, using the grease fitting (key 28,
Figure 7). Line pressure leakage or unexpected grease extrusion from the actuator vent (key 27, Figure 7) during normal operation indicates stem O-ring damage. All O-rings, gaskets and seals should be lubricated with a good grade general-purpose grease and installed gently rather than forced into position. Be certain that the nameplates are updated to indicate accurately
any field changes in equipment, materials, service conditions or pressure settings.
!Warning
To avoid personal injury resulting from sudden release of pressure, isolate the pilot or regulator from all pressure and cautiously release trapped pressure from the pilot or regulator before attempting disassembly.
Type EGR Main Valve
Replacing Quick-Change Trim Package
Perform this procedure if replacing the entire trim package (Figure 3). Key numbers for both the complete main valve and its trim package are referenced in Figure 6.
Note
All disassembly, trim change, and reassembly steps in this section may be performed with the regulator in the main line.
1.Remove the cap screws (key 3) on a cast iron or steel body, or remove the stud bolt (key 29, not shown) on a stainless steel body. Pry the body flange
(key 2) loose from the valve body (key 1), and lift out the trim package (Figure 3).
2.Perform any required inspection, cleaning or maintenance on the exposed surfaces of the valve body or trim package. Replace the gasket (key 4) or cage O-ring (key 17) as necessary.
3.On a pre-built replacement trim package, check indicator zeroing by unscrewing the indicator protector
(key 19) and seeing if the flange of the flange nut
(key 22) lines up evenly with the bottom marking on the indicator scale (key 18). If not, remove the indicator scale and separate the flange nut and hex nut (key 8). Hold the indicator scale against the indicator fitting (key 5) with the scale base resting
against the shoulder of the fitting, and turn the flange nut until its flange is aligned with the bottom scale marking. Then lock both nuts against each other, and install the indicator scale and protector.
4.Lightly coat the cage seating surfaces of the valve body (key 1) web and the body flange (key 2) seating surfaces of the valve body neck with a good grade of general-purpose grease. Install the trim package, and secure it evenly with the cap screws or stud bolt nuts (key 29, not shown). No particular trim package orientation in the body is required.
Replacing Trim Parts
Perform this procedure if inspecting, cleaning or replacing individual parts in a trim package. Key numbers are referenced in Figure 6. An exploded view of a standard full-capacity trim package only is shown in Figure 4.
Note
Access to the spring (key 9), indicator fitting O-ring (key 21) or travel indicator parts in step 1 can be gained without removing the body flange (key 2).
1.Remove the indicator fitting (key 5) and attached parts. Proceed to step 5 if only performing maintenance on the fitting or attached parts.
2.Remove the cap screws (key 3) on a cast iron or steel body, or remove the stud bolt (key 29, not shown) on a stainless steel body, and pry the body flange (key 2) loose from the valve body (key 1).
3.Use the valve body (key 1) as a holding fixture if desired. Flip the body flange (key 2) over, and anchor it on the valve body as shown in Figure 5, removing the pipe plug (key 31) first.
4.To gain access to the port seal (key 12), upper seal (key 15), or valve plug parts, unscrew the seat ring (key 13) from the cage (key 11) and the cage
