What is the check?

Wuxi east technology co. , LTD. Is a collection of the control valve industry manufacturing, development, production, assembly, sales and service in the integration of science and technology enterprises, professional research and development of electric valve, pneumatic valves, hydraulic valves, pneumatic actuators and various kinds of complete sets of pneumatic valve. Our company produce all kinds of pneumatic ball valves, butterfly valves, plug valves, regulating valve, gate valve, globe valve, flat gate valve and pneumatic device or valve products. This kind of valve is used to prevent the backflow medium, the use of fluid kinetic energy to open itself, shut down automatically when reverse flow. Standing in the water pump, hydrophobic and other exports do not allow fluid flow. Swing check valve points, lift and the wafer three. For the swing check valve, fluid can flow from left to right, and shut down automatically when reverse flow. For the lift check valve, fluid flows from left to right, and the valve core is raised, forming pathway, reverse flow when the valve core is pressed close to the seat and shut down. For the wafer check valve, fluid flows from left to right, and the valve core is open, forming pathway, reverse flow when the valve core is pressed close to the seat and shut down, wafer check valves can be installed in several, small volume, light weight, compact structure.
