– DESCRIPTION –
COVNA HK07 Pilot Operated Diaphragm Solenoid valve with less power consumption for longtime working. Applied to pressure system opened from 0.3 bar. Max pressure is 16 bar. Longtime working. Support Brass or Stainless steel body material.
In the case of a pilot operated solenoid valve, it uses system air pressure as a pilot to actuate the spool. For many OEM’s that are still using direct acting solenoid valves in their pneumatic manifolds, it might be worthwhile to consider moving to pilot actuated valves to ease installation, reduce footprint, save money, and allow fieldbus communication.
