Model:RDF(Flange Type)、RDT(Thread Type)

Flange Type

Product accent:
  • The gate is designed for opening status, which will not influence the water supply function under unstable inlet pressure condition.
  • When the outlet pressure responds directly to the pressure control chamber and adjust the setting pressure, it responses quickly and adjust the pressure accurately.
