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.
