– Description –
Cokver HT01 is a low-power pilot-operated diaphragm solenoid valve, suitable for long-term operation. Suitable for pressure systems, with an opening pressure of 0.3 bar and a maximum pressure of 16 bar. The valve body material can be either brass or stainless steel.
For pilot-operated solenoid valves, they utilize system air pressure as a pilot signal to drive the valve core. For many original equipment manufacturers (OEMs) that still use direct-acting solenoid valves in pneumatic manifolds, considering a switch to pilot-operated solenoid valves may be worthwhile, as this can simplify installation, reduce footprint, save costs, and support fieldbus communication.
