6 FAQs about [Accumulator charging valve type]
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 does the charging valve do when accumulator pressure is low?
If pressure in one or both accumulators is below a specified pressure range, the charging valve sends a pressure signal to a pressure and flow compensated pump. The load sensing accumulator charging valve operates in a low and pressure on demand system.
How does a load sensing accumulator charging valve work?
The load sensing accumulator charging valve operates in a low and pressure on demand system. If pressure in one or both accumulators is below a specified pressure range, the charging valve sends a pressure signal to a pressure and flow compensated pump.
What happens when accumulator is charging?
short time when the accumulator is charging. This does not noticea ly affect the operation of these components. Full system pressure is available to the downstream secondary hydraulic devices at all times provided oil delive y and pressure from the pump is not impeded.The accumulator charging valve incorporates a full flow relief valve to limit
When does the accumulator charging valve stop sending the pressure signal?
The accumulator charging valve stops sending the pressure signal when pressure in the accumulators reaches the high limit of the charging valve. This valve is connected to the hydraulic system in parallel to other load sensing valves, and the highest demand for pressure determines the operating pressure of the system.
