This is a pilot-operated, balanced piston sequence valve. When pressure at port 1 exceeds the predetermined pressure, the valve opens to supply flow to a secondary circuit, allowing bi-directional flow between port 1 and port 2. The valve is insensitive to backpressure at port 2 up to the valve setting. This valve can function as a 2-port relief valve in sub-system rises higher than the setting of the valve directing excess fluid to tank. 

  • When the pressure drop across the relief valve is high, cavitation can easily occur, leading to noise and manifold erosion. If this is a concern, please refer to the balanced poppet type SP-17A-3G-Y-Z.
    Pressure at port 3 is added directly to the valve setting in a 1:1 ratio, and must be less than 350 bar (5000 psi).
