Relief Valves

Introduction

Please note: These regulators and relief valves must

be installed, operated and maintained in accordance

with CVS instructions and all applicable federal,

provincial, state and local codes, laws, rules, and

The CVS 630 HP Series consists of a high pressure

reducing regulator, and Type CVS 630R relief valve.

These regulators and relief valves are furnished in

either spring-loaded or pressure-loaded construction

with 1 or 2 inch NPT screwed end connections and

normally furnished without a main regulator spring

and use a Bellofram 7360 or a Bellofram P39

regulator.

Pressure loaded Type 630R relief valves are

furnished with a light rate relief valve spring and use

a Bellofram 7360 or a Bellofram P39 regulator.

for shipping damage. Be certain the body cavity and

seat ring are free from any foreign material. Also be

certain that connecting pipelines are free of loose

pipe scale.

position, but direction of flow through the body must
