Description
The Hawe CNE shut-off valve is a type of pressure control valve. It receives control oil from a high-pressure circuit and switches the delivery flow from a low-pressure pump to unpressurised circulation once the pressure value set has been reached. During this process, the consumer side is separated from the idle circulation by a zero-leakage check valve. If the pressure on the consumer side drops below the pressure setting, the idle circulation is interrupted and the oil is fed to the consumer again.
Shut-off valves or accumulator charging valves are a type of pressure control valve. They switch the delivery flow of a pump to unpressurised circulation if the pressure value set is reached. During this process, the consumer side is separated from the idle circulation by a zero-leakage check valve. If the pressure drops in the consumer side, the idle circulation is interrupted and the oil is fed to the consumer again.
Via a control line, the higher pressure in the high-pressure circuit holds open the pressure-controlled two directional valve, and with it, the idle circulation. In the low-pressure circuit the valve acts simultaneously as a pressure-limiting valve.
The compact design of the CNE valve means it is easily screwed-in and integrated into control blocks. The necessary mounting holes are also easily produced.
Key technical specifications of the Hawe CNE include:
- Maximum pressure: 420-500 bar
- Flow rate: 30 litres per minute
Common applications include dual-stage systems (high-pressure, low-pressure) and jigs
