Pressure reducing valve (for water / liquid / door-to-door water supply), constant flow valve, water hammer preventer
RD-25SN type pressure reducing valve for water supply

A pressure reducing valve used to supply water to small hot water boilers and electric water heaters, and can be installed horizontally or vertically. Use for cold regions with a drain plug in places where there is a risk of freezing, such as in cold regions.

Major features

Durability is improved by adopting chlorine water resistant EPDM. (RD-50SN type series)
Vertical and horizontal piping is possible. (Excluding strainer cap upward)

Specification:

The face-to-face dimensions differ between the RD-25SN type series and the RD-50SN type series.
The pressure reducing valve for door-to-door water supply is the Benkei series. (Refer to pages 50-66.)
