COVNA 2W Series Direct lifting diaphragm Solenoid Valve

● Direct lifting diaphragm construction with high frequency.

● Structure: Direct Acting Diaphragm / Pilot Diaphragm

● Features: Zero Leakage, Fast Acting, etc

● Open from 0 bar with large flow rate(Zero pressure to start)

● Function: Normally Closed / Normally Open

● Applied to low pressure system.

● Temperature: Normal Temperature(-10℃~80℃), Medium Temperature(-10℃~120℃)

● Suitable for water, air, gas, etc.




A two way diaphragm solenoid valve means that there are 2 ports in which fluid flows from/to. The Direct Acting valves will stop flow in either direction, but are still only designed to allow full flow in a single direction. Semi-Direct acting valves require assitance from fluid flow to open.These 2W valves may be used with 0 psi working pressure.
