Introduction

Scope of the Manual

This manual provides instructions for installation, 

adjustment, maintenance, and parts ordering information 

for the Type FL relief valve or backpressure regulator 

with a Type PRX/182 pilot sold in North America.  Any 

accessories used with this relief valve or backpressure 

regulator are covered in their respective manuals.

Description

The Type FL relief valve or backpressure regulator are 

accurate pilot-operated, relief valve or backpressure 

regulators designed for high-pressure transmission/city gate, 

large capacity distribution systems, and power plant feeds.  

The Type FL relief provides smooth, reliable operation, tight 

shutoff, and long life.  The main valve actuator moves in 

response to the pilot loading pressure to control upstream 

system pressure.  

Principle of Operation

A pressure relief valve is a throttling pressure control 

device that opens and closes to ensure the inlet pressure 

does not rise above a predetermined pressure.  Tartarini™

 

relief valves cannot be used as ASME safety relief valves.  

A backpressure regulator is a device that controls and 

responds to changes in the upstream pressure.  It functions 

the same as a relief valve in such a way that it opens on 

increasing upstream pressure.

Relief Valve

As long as the inlet pressure is below the set pressure,

the pilot control spring keeps the pilot valve plug closed.  Inlet 

pressure passes through the restrictor and registers as loading 

pressure on the main valve diaphragm chamber.  Force from
