Connexion Direct Acting Cast Iron Pressure Reducing Valve
 
Connexion Range of Flanged Direct Acting Pressure Reducing valves adopts NO gate design, hence water supply will not be affected due to instability in inlet pressure.

The internal pressure control chamber is a diaphragm design, hence the function and life-time will not be affected by water impurity and there is no leakage by this design.

When the outlet pressure directly responds to pressure control chamber to adjust setting pressure the response is sensitive and adjustment is very precise.
