Pilot valve accumulator

What is a pilot accumulator?

A pilot accumulator is a small accumulator, approximately 0.01 m3 (0.25 ft3) volume, used in conjunction with pilot operated relief valves. It comes with necessary fittings, valves, and test gauges for mounting and testing of the pilot.

How do accumulators work?

Its function is to control the charging of the accumulator within a pre-set switching range. There are integrations of a pilot stage with clear hysteresis, the main piston and a check valve into the circuit. Therefore, the charge of the accumulator happens at port A from the pump port P across the check valve.

What is accumulator charging valve?

The accumulator charging valve is a cartridge unit with a seated pilot stage and a spool-type main stage and leak-free ball-type pilot stage. The changeover to unloaded bypass is a soft-switching one, with damped switching characteristics. sure circuit. For this purpose, either the 'Off' pressure or the 'On' pressure of the cartridge can be set.

What are the components of accumulator charging valve?

The main components of the valve are a body and a mechanically self-operated two-stage pressure-unloading cartridge. The accumulator charging valve is a cartridge unit with a seated pilot stage and a spool-type main stage and leak-free ball-type pilot stage.

What is the accumulator charging valve DLHS D / R?

The accumulator charging valve DLHS D / R is a pilot-operated, spring-loaded spool valve mounted in a manifold or inline housing. Its function is to control the charging of the accumulator within a pre-set switching range. There are integrations of a pilot stage with clear hysteresis, the main piston and a check valve into the circuit.

How does the HYDAC DL10 accumulator charging valve work?

The HYDAC DL10 accumulator charging valve is a direct operated, spring-loaded spool valve. In the spring-loaded position, the oil can flow from port 2 to port 3 to the accumulator. If the pressure at port 1 increases, the spool is pushed against the spring and blocks port 2.
