Sequence and Unloading Valves

Our pressure control valves keep hydraulic circuit pressure on an even keel.

We offer flow and pressure capabilities of 1-190 l/min [0.3-50 US gal/min] and up to 415 bar [6,000 psi], respectively.

Sequence Valves

Sequence Valves Example Schematic

Pressure signal shifts the spool, opening or closing a flow path at a pre-set pressure. Used to control a sequence of operations for two or more actuators in a system. Many functional options available for a wide range of applications. Flow range: 4-150 l/min [1-39 US gal/min]. Pressure capability up to 350 bar [5,080 psi].

 

Unloading Valves

Unloading Valves Example Schematic

Type of sequence valve that uses a remote pressure signal to unload a circuit. Commonly used for unloading an accumulator charging circuit or unloading a pump to tank at minimum pressure. Flow range: 4-160 l/min [1-42 US gal/min]. Pressure capability up to 350 bar [5,080 psi].
