G3/8'' Hydraulic 2/2-Way Solenoid Valve NO Bidirectional 350bar 24VDC

Normally open: the line stays open until the coil is energised, and it opens again on a power failure. Pilot operated, so it needs at least 10 bar across the ports to switch - not for unpressurised or gravity-return lines. It shuts off in both directions, so either port can be the pressure side. Size it by flow: 10 to 40 l/min. For more, choose the G1/2 valve (20 to 50 l/min). The coil accepts 21.6 to 26.4 V (24 V DC ±10 %). The emergency release screw relieves port 2 to port 1 by hand with the valve closed.

Pros:

• Leak-free poppet seat shut-off
• Shuts off in both directions when closed
• Emergency release screw relieves port 2 to port 1 by hand
• IP65: dust-tight and protected against low-pressure water jets
• Supplied with coil and connector

Cons:

• Pilot operated, needs 10 bar differential - not for unpressurised or gravity-return lines

Series:

Pilot-operated 2/2-way hydraulic solenoid valves with a poppet seat, for leak-free shut-off of oil lines up to 350 bar. The range covers G1/4, G3/8, G1/2 and G3/4 BSPP female ports, with nominal flows of 5-20, 10-40, 20-50 and 30-70 l/min respectively. Every size is available normally closed or normally open, and unidirectional or bidirectional. In the closed position, unidirectional valves block port 2 to port 1 and let flow from 1 to 2 pass like a check valve; bidirectional valves block both directions. Available with a 12 V DC, 24 V DC or 230 V AC coil. Aluminium bodies are rated 10 to 250 bar, galvanised steel bodies 10 to 350 bar. All versions have a galvanised steel screw-in cartridge, NBR seals and an emergency release screw that relieves port 2 to port 1 with the valve closed. The coil draws 20 W on DC or 22 VA on AC, tolerates ±10 % voltage and is rated IP65. Suitable for mineral-oil hydraulic fluids from -20 to +80 °C at ambient temperatures of -30 to +90 °C. Every valve is supplied with coil and connector. Also known as 2/2 seat valves or poppet-type hydraulic shut-off valves.
