If you’re in need of check valves, you’ve come to the right place. We’ve outlined the difference between Ball, Lift, Poppet-style, and Double check valves, and given you the specs on each one. Now it’s time to choose a manufacturer! We’ll explain the differences between these types of valves, and help you decide which one is best for your application. Read on for more information!
Double check valves
Check valves are an essential part of many industrial processes, including those in the chemical, petrochemical, pharmaceutical, and steel industries. They are also used in domestic water distribution to control the flow of water, wastewater, and treated water. Their maintenance includes the examination of their base metal pressure containing components. Manufacturers such as Oilway also offer consultations on valve maintenance. Read on to learn more about the benefits of double check valves manufactured by check valve manufacturers.
Lift check valves
A lift check valve is a type of regulating valve that is used in a fluid process. Unlike swing check valves, lift check valves change direction during flow. The upward flow forces the piston or ball to move upward, then downwards to close the valve. This action is facilitated by the dashpot. Manufacturers also make lift check valves in vertical designs for mounting on piping. Here are some tips to choose the right type of lift check valve for your application.
Poppet-style check valves
A poppet-style check valve is a specialized type of valve that features minimal leakage and a low pressure drop. They are used in systems that are up to 250 bar. Listed below are some of the advantages of this type of valve. In addition to the benefits of their low leakage, they also feature zinc-plated external parts and are designed for maximum efficiency. And because they close quietly and without causing water hammer, they are an excellent choice for low-pressure applications.
Ball check valves
A ball check valve is a type of pressure-relief valve that uses a rubber coated ball to seal against backflow. They can be installed in both vertical and horizontal pipelines and are typically used in applications that require low pressure. During the forward flow of fluid through the valve body, the ball rotates and keeps the body clean. Unlike other types of check valves, there are no parts that can wear out or fail. There are a number of ball check valve designs available in a wide range of materials, including stainless steel.
Wafer check valves
A wafer check valve is a type of safety valve that is less bulky than other check vales. Its design makes it easy to install between flange rims. A flange is the raised connecting piece between two pieces of pipe. This design allows a wafer check valve to easily fit between flange rims in larger plumbing systems. This means that they are especially useful for applications that require full flow.
Non-modular check valves
Non-modular check valves allow free flow in one direction while preventing the reverse flow. They operate by blocking reverse flow and restoring movement when an automatic pilot pressure signal is received. Non-modular check valves are typically mounted directly on the actuator or in close proximity to it, either flange mounted or through a metallic pipe. When selecting non-modular check valves, consider your needs and your budget.
