DEMA 412 Series Brass Pilot Piston 3/8" 150 PSI Normally Closed Solenoid Valves

DEMA’s 412 series pilot-piston valves feature 3/8" NPT connections, have brass bodies, stainless steel seats, and Teflon seals. With pilot-piston valves, the stem and plunger assembly opens the port. This releases the pressure on top of the piston, which moves upward and opens the main valve port.
