1305 Series Pressure Reducing Regulators

Fisher

regulators must be installed,

operated, and maintained in accordance

with federal, state, and local codes, rules

and regulations, and Emerson Process

Management Regulator Technologies,

Inc. instructions.

If the regulator vents gas or a leak

develops in the system, service to

the unit may be required. Failure

to correct trouble could result in a

hazardous condition.

Call a gas service person to service

the unit. Only a qualied person must

install or service the regulator.

Introduction

The 1305 Series regulators are direct-operated,

pressure-reducing regulators that resist hydrate

formation and regulator freeze-up. Regulator

freeze-up resistance occurs as the pipeline gas

warms the nned inlet adaptor and the orice area.

As the gas cools within the inlet adaptor due to

pressure drop and volume expansion, the warm inlet

adaptor helps keep the gas temperature above the

freezing point of water and the hydrate formation

temperature. The regulators are suitable for service

with natural gas, air, propane, and other gases

compatible with the internal parts.

Type 1305C—1 NPT inlet and 1/4 NPT outlet

connections; 5/64-inch (2,0 mm) orice diameter.

Three springs provide 0 to 225 psig (0 to 15,5 bar)

reduced pressure ranges.

WARNING

Type 1305D—same as Type 1305C except with larger

spring case and just one heavy spring for reduced

pressure range of 200 to 500 psig (13,8 to 34,5 bar).

Principle of Operation

Downstream pressure is sensed by the diaphragm

(see Figure 3) through a registration hole in the

bafe. When downstream pressure rises, pressure

under the diaphragm overcomes the spring

compression and moves the valve lever upward.

This action pushes the valve disk closer to the

orice, reducing ow through the body. Downstream

pressure returns to the setpoint value. When

downstream pressure decreases, the opposite action

takes place. The valve disk moves away from the

orice, ow through the body increases, and the

downstream pressure returns to the setpoint value.
