4.Functions,section,symbols of the Check Valve Sandwich Plate Z1S
The Z1S valve is a direct operated check valve in sandwich plate design. It is used for the leak-free closure in one direction and allows free-flow in the counter direction. This valve type has a metallic seal between poppet (3) and housing (1). Check valves of Z1S type are especially suitable for applications with operating pressures above 10.0 MPa and flow velocities over 4 m/s.
1. The fluid must be filtered. Minimum filter fineness is 20 ㎛.
2. The tank must be sealing up and an air filter must be installed on air entrance.
3. Products without subplate when leaving factory, if need them, please ordering specially.
4. Valve fixing screws must be high intensity level (class 10.9). Please select and use them according to the parameter listed in the sample book.
5. Roughness of surface linked with the valve is required to 0.8.
6. Surface finish of mating piece is required to 0.01/100mm.
