high quality Stainless Steel SS304 Sanitary Check valve Non Return Valve
Application: The check valve is a valve that prevents liquid from flowing back, ensuring unique flow. It can be used to protect the loss of fluid back-up and prevent pipe blows. Widely used in food, beverage, brewing, oil refining, cosmetics, pharmaceutical and other industries.
Principle of operation: When the pressure of the fluid is greater than the suction pressure of the spring, the valve opens. When the two pressures are equal, the valve closes. A more powerful differential pressure can also close the valve.
