Multi-way valve for high pressure fluids - is four way valve with metal valve seats for controlling double acting hydraulic pistons

摘要

The multiway seat valve is for fluid media under high pressure, esp. high pressure water for controlling double-acting hydraulic pistons, where the valve is in the form of a four way valve with metal valve seats. The valve can be changed over by a pre-control valve. There are two separate, but connected, double-coned valve bodies to seal or expose two hydraulic fluid feeds or returns. The valve bodies have two cylindrical appendages, with which they are supported in inserts arranged in the valve housing.
