The primary function of a check valve is to prevent reverse flow, which can damage pumps and other mechanisms. When a check valve closes, it can cause water hammer, where the fluid in the system slams against the closed valve. This necessitates that check valves be resilient, durable, and...
Swing Check Valves are available in straight body design and y-pattern design. The disk is suspended from the body by means of a hinge pin and seals against the seat which is integral with the body. These valves are typically used in sizes 2 inches and over. Swing check valves can be i...

WHAT'S COMMON TO ALL TYPES OF CHECK VALVES? There is a wide range of check valve types, and while each operates somewhat differently, all check valves share a few commonalities. Compared with other types of valves, check valves are relatively simple and inexpensive to purchase. These types of...
When using valves, it is necessary to choose the appropriate valve type and specification based on specific application scenarios and requirements. Choosing the appropriate valve can ensure the normal operation of the system and ensure the accuracy and reliability of fluid control. In addition, regular...

This type of valve gives you excellent control of liquid flow through the valve and a secure shutoff when closed. They are often used in sewage treatment, chemical, and paper plants. 2. Check Valves These types of valves prevent the reversal of fluid flow in piping. Check valves remain ope...

This design trick makes check valves equipped with an orifice a flow control tool. There are also three-way valves (or “shuttle” valves), which have the characteristic of conveying to the return line of the circuit the greater of the pressures of the two delivery lines. Differences Between...
Types of Control Valves In a control loop, these valves act as the correcting element. There are hand-operatedcontrol valves, but typically they work automatically. Examples include ball and plug valves, needle valves, butterfly valves, and check valves to name a few. ...
