High/low Pressure Switching Valve

By efficiently understanding the market trends, we are able to manufacture and supplied an High/Low Pressure Switching Valve in Satara, Maharashtra, India. The High/low pressure switching valve ZHD/ND allows you to choose between two pressure levels for the outgoing P channel:

High pressure (HD) = supply pressure in the P channel
Low pressure (ND) = set pressure of the 3-way pressure control valve
Switching is done electrically via a 2/2-way poppet valve. The low pressure is given when the poppet valve is open, allowing the pilot oil of the pressure control valve to flow into the tank (T channel). Oil flows into the outgoing P channel until the setpoint pressure is reached, which then closes the pressure control valve. As soon as the pressure goes below the setpoint pressure, the valve opens up again. By selecting high pressure, the pressure regulator is put out of function, which allows oil to flow with little resistance through the Sandwich plate. As standard, the poppet valve is set to the neutral position "normally open", but it is also available as "normally closed".
