Pump valve

unloading

As the name implies, sequence valves control a sequence of operations. Sequence valves usually use a pressure signal to shift a spool, thereby opening or closing a flow path at a pre-set pressure. - 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]. - 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.
