2. Material
(1). - Body: Stainelss steel
(2). - Disc: Stainless steel
(3). - Spring: stainless steel
(4). - Cover: alloy
3. Nominal Diameter & Pressure
Diameter: 15~200
Pressure: 150
4. Features
Lift check design: The lift check valve has a disc that is lifted off its seat to allow flow in one direction. When the fluid flow reverses, the disc falls back into its seat, preventing backflow.
Spring-loaded or weight-loaded: The valve can be spring-loaded or weight-loaded to ensure the disc returns to its closed position quickly and reliably.
Pressure rating: The "150" in the name refers to the pressure rating of the valve, which is 150 pounds per square inch (psi). This means that the valve is designed to withstand a maximum pressure of 150 psi without leaking or failing.
