Cavity: T-17A
Capacity: 60 gpm
Maximum Operating Pressure: 5000 psi
Pilot Ratio: 3:1

This valve is a pilot to open check valve. It has a non-sealed pilot, a steel seat, and is non-vented. It allows free flow from the valve (port 2) to the load (port 1) and blocks flow in the opposite direction. Pressure at the pilot (port 3) will open the valve from port 1 to port 2. Pilot pressure needed at port 3 to open the valve is directly proportional to the load pressure at port 1. Pressure at port 2 directly opposes pilot pressure.

Cavity: T-2A
Capacity: 30 gpm
Maximum Operating Pressure: 5000 psi
Pilot Ratio: 3:1
Maximum Valve Leakage at 110 SUS (24 cSt): 1 drops/min.
Valve Hex Size: 1 1/8 in.

Counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio.
