Product Description

Pilot-Piston Water Valve

A pilot operated brass solenoid valve with 24VDC coil. This valve has stainless steel pistons and seats as well as a sleeve. Operates the same as a pilot operated valve. However, the pilot port is located in a separate chamber from the piston allowing operation close to the top plug using more force and a higher opening pressure.
