Circuit valve, primary pressure control valve
WVM-02 type primary pressure control valve (for water)

This is a large-capacity primary pressure control valve that releases an excessive amount of pressure at the desired pressure due to load fluctuations in pipes and circuits such as air conditioning and sanitary equipment, and keeps the pressure on the primary side of the valve constant.

Major features

Stable operation can be easily obtained by adjusting the sensitivity by adjusting the needle valve opening according to the usage conditions.
The basic valve and pilot valve can be easily disassembled for easy maintenance such as adjustment, repair, and parts replacement.
The lift limiting mechanism can limit the overflow.

Specification:

We also manufacture WVM-02PN type (main body inner and outer surface epoxy resin powder coating) and WVM-02N type (main body inner surface water supply liquid epoxy resin coating) that conform to the performance standards of the Waterworks Law (main body material FC, nominal diameter 80-200). doing.
We also manufacture one with a pressure gauge. (The maximum scale of the pressure gauge is the set pressure adjustment range L (0.6MPa), M (1.6MPa).)
Please refer to page 157 of the general catalog for the nominal diameter selection chart and page 175 for the piping example diagram
