COVNA Normally Open 24V DC 2 Way Pilot Operated Solenoid Valve
COVNA diaphragm 2/2 way Fluid Control solenoid valve with brass or stainless steel body, 1/4 inch~1inch threads and a 24V DC coil. The circuit function of the solenoid valve with normally closed and normally open. Suitable for systems with an operating pressure of 0 bar to 4 bar and a maximum temperature of 120 °C. Suitable for clean media (max 120°C) and an operating pressure of 0-4bar . Brass housing with FKM seal. PTFE and NBR seal are also vailable. Timer can be equipped with the solenoid valve.
- Model: HK2231015
- Size Range: 1/4''~1''
- Pressure Range: 0.03MPa-1.6 MPa
- Material: Stainless Steel or brass
COVNA HK2231015 Stainless Steel NPT Thread Solenoid Ball Valve
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.
1. Special structure reduces the transient pressure to preventwater hammer phenomena which will protect the valve and pipe system
2. Change the piloted head, can be used withexplosion-proof coil Ex mb I/II T4
3. Life span can be at 1 million cycles
4. Opened from low pressure with large flow
5. Low noise, stable work
