RDB-33FN type pressure reducing valve with bypass (for water / hot water)

A pressure reducing valve that integrates the functions of decompression + bypass + closing makes it possible to effectively use space and reduce equipment costs.
It inherits the reliability and ease of use of the water pressure reducing valve [calm] series.

Major features

Uses a ball-type switching valve system that facilitates function selection operations.
Bypass function enables cleaning and water flow in the pipe at the initial stage of water flow.
Withstand voltage test of piping is possible with the pressure reducing valve with bypass attached.
Maintenance of the pressure reducing valve is possible while passing water.
