Specications

Available Constructions

Type 627: Direct-operated pressure reducing

regulator equipped with a pitot tube for greater regulated capacities. Type 627R: Type 627 with internal relief and with an open throat.

Type 627LR: Type 627R with light rate relief spring Type 627M: Type 627 with a stem seal between

the body outlet pressure and diaphragm case. Pressure is measured under the diaphragm through the 1/4 NPT downstream control line connection.

Type 627MR: Type 627M with internal relief. Type 627H: Type 627 with a diaphragm limiter to

deliver a higher outlet pressure. Type 627HM: Type 627H with a stem seal between the body outlet pressure and diaphragm case. Pressure is measured under the diaphragm through two 1/4 NPT downstream control line connections.

Installation

WARNING

Only qualied personnel should install or

service a regulator. Regulators should be installed, operated, and maintained in accordance with international and applicable codes and regulations, and manufacturer’s instructions.

If the regulator vents uid or a leak

develops in the system, it indicates that service is required. Failure to take the regulator out of service immediately may create a hazardous condition.

Personal injury, equipment damage, or

leakage due to escaping uid or bursting of

pressure-containing parts may result if this regulator is overpressured or is installed where service conditions could exceed the

limits given in the Specications section and

Tables 1 and 2, 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 the appropriate code,

regulation, or standard) to prevent service conditions from exceeding limits.

Additionally, physical damage to the regulator could result in personal injury and property

damage due to escaping uid. To avoid such

injury and damage, install the regulator in a safe location.

(1)

1. The pressure/temperature limits in this Installation Guide and any applicable standard or code limitation should not be exceeded.

2. Types 627, 627H, 627R, and 627LR are limited by maximum diaphragm casing pressure.

3. Temperature may decrease these maximum pressures.

1. For inlet pressure in excess of 69,0 bar (1000 psig), refer to the maximum body and disk pressure ratings in the Specications section.

2. For pressure settings under 0,69 bar (10 psig), inlet pressure should be limited to approximately 6,90 bar (100 psig) so the setpoint adjustment can be obtained.

3. The unbalance forces change from the wide-open monitor mode to an active regulator mode such that the Type 627M or 627MH should have a 9,5 mm (3/8-inch) or larger orice.

- Shaded areas indicate that Fluorocarbon (FKM) or Nylon (PA) disk material is not available.

Clean out all pipelines before installation of the regulator and check to be sure the regulator has not been damaged or has not collected foreign material during shipping. For threaded NPT bodies, apply pipe compound to the male pipe threads.

For anged bodies, use suitable line gaskets and approved

piping and bolting practices. Install the regulator in any

position desired, unless otherwise specied, but be sure ow

through the body is in the direction indicated by the arrow on the body.

627 Series

Note

It is important that the regulator be installed so that the vent hole in the spring case is unobstructed at all times. For outdoor installations, the regulator should be located

away from vehicular trafc and positioned

so that water, ice, and other foreign materials cannot enter the spring case through the vent. Avoid placing the regulator beneath eaves or downspouts, and be sure it is above the probable snow level.

Overpressure Protection

The recommended pressure limitations are stamped on the regulator nameplate. Some type of overpressure protection is needed if the actual inlet pressure exceeds the maximum operating outlet pressure rating. Overpressure protection should also be provided if the regulator inlet pressure is greater than the safe working pressure of the downstream equipment.

Regulator operation below the maximum pressure limitations does not preclude the possibility of damage from external sources or debris in the line. The regulator should

be inspected for damage after any overpressure condition.

Table 2. Maximum Spring and Diaphragm Casing Pressure

Startup

The regulator is factory set at approximately the midpoint of the spring range or the pressure requested, so an initial adjustment may be required to give the desired results. With proper installation completed and relief valves properly adjusted, slowly open the upstream and downstream shutoff valves.

Adjustment

To change the outlet pressure, remove the closing cap or loosen the locknut and turn the adjusting screw clockwise to increase outlet pressure or counterclockwise to decrease pressure. Monitor the outlet pressure with a test gauge during the adjustment. Replace the closing cap or tighten the locknut to maintain the desired setting.

Taking Out of Service (Shutdown)

WARNING

To avoid personal injury resulting from sudden release of pressure, isolate the regulator from all pressure before attempting disassembly.

(1)

MAXIMUM PRESSURE DESCRIPTION

Maximum pressure to spring and diaphragm casings to prevent leak to atmosphere other

than relief action (internal parts damage

may occur).

Maximum pressure to spring and diaphragm

casings to prevent burst of casings during

abnormal operation (leak to atmosphere and

internal parts damage may occur).

Maximum diaphragm casing overpressure

(above setpoint) to prevent damage to

internal parts.

1. If the spring case is pressurized, a metal adjusting screw cap is required. Contact your local Sales Ofce for details.
