MODEL: WVR-02
Pressure reducing valve (for water / liquid / door-to-door water supply), constant flow valve, water hammer preventer
WVR-02 type pressure reducing valve (for water / hot water)

A large-capacity pressure reducing valve used for the main water supply line for air conditioning, sanitary equipment, and field irrigation. Since the pilot valve uses a pressure balance mechanism, the pressure on the secondary side can be adjusted to a constant level without being affected by fluctuations in the pressure on the primary side.
For fire extinguishing equipment, please use WVR-02T, 05T type or RD-51T type, which are certified by the Fire Equipment and Safety Center of Japan. See pages 81 and 82)

Where to use: Building equipmentFactory equipmentUpland irrigation

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 adjustment, repair and parts replacement.
The lift limiting mechanism can limit the overflow.

Specification:

WVR-02PN type (main body inner and outer surface epoxy resin powder coating, nominal diameter 80-200), WVR-02N type (main body material FC, liquid epoxy resin coating for inner water supply, nominal diameter 80-200) 300) is also manufactured. (Excluding JIS 16K RF flange made by FC)
