CVS Type 630 HP
Regulators and
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
regulations.
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.
Pressure loaded Type 630 HP regulators are
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.
Installation
After uncrating the regulator or relief valve, inspect it
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.
The regulator or relief valve may be installed in any
position, but direction of flow through the body must
be as indicated by the flow direction arrow on
nameplate.
