Sandwich plate valve for use in vertical stackings Porting pattern according to ISO 4401-05-04-0-05 and ISO 4401-05-05-0-05 Various one and two-channel blocking functions Perfect leak-tightness due to poppet made of high-performance plastic Corrosion-protected design Easily adjustable to special hydraulic fluids by exchanging the external seal rings Cost-effective replacement of wear parts thanks to individually available check valve installation sets With measuring ports, optional Throttle check valve, optional The valve type Z1S is a direct operated check valve in sandwich plate design. It is used for the leakage-free blocking in one direction and allows for free flow in the opposite direction. The stroke of the plastic poppet (1) is limited by the plastic socket (2). The installed spring (3) supports the closing movement. When no fluid flows through the valve, the spring (3) keeps the plastic poppet (1) in closed position. Optimum leak-tightness is already achieved at low pressures (0.1 x pmax). Notice: For all installation positions in which the plastic socket (2) is mounted at the plate side ➁, no additional seal ring may be used at this position! At the component side ➀, the seal ring (as usual) seals the assembly installed downstream. The installed plastic socket (2) has a sealing function and may not be removed or damaged. Protrusion of the plastic socket (2) is required for design reasons (preload). Dependent on the included hydraulic fluid volume and its temperature variations, static pressure changes, which are not caused by leakage at the seat face, may occur.
