The PC08-30 is a screw-in, cartridge style, pilot operated, hydraulic check valve used for blocking or load holding circuits.

It allows free flow from port 2 to 3, while normally blocking flow from port 3 to 2. Flow will be allowed from port 3 to 2 when pressure is applied at port 1.

• Hardened seat for long life and low leakage.
• Optional sealed piston.
• Optional spring ranges.
• Compact size.
