What is the difference between wafer check valve and swing check valve?

Wafer check valves get their name from their wafer thin design. Swing check valves, as the name implies, also uses a swinging disc to allow or block flow. The difference between the two is in the body design. Swing check valves are not designed for extremely tight spaces like the wafer check.

What is a Retainerless Wafer check valve?

In many check valves, there are four holes in the body of the valve that are used to mount the hinge pin and stop pin. A retainerless design does not have any holes passing all the way through the body of the valve.

What are the different types of check valves?

The three main types of check valves we offer are ball, piston, and stop check valves.

What type of check valve is best?

Lift Check Valves They have no external moving parts and are known to be economical and reliable. Over time, these types of valves can have high energy costs because the disc remains in the flow stream during operation. Silent check valves are known for their quiet closure. Flow pushes the disc to allow forward flow.

What is the difference between a lug type butterfly valve and wafer?

The difference between a Wafer and Lug type Butterfly valve is only the mounting scheme [1] and [2]. Wafer type valves don’t have attachment lugs, though them may have alignment lugs. They are sandwiched between the flanges on the ends two lengths of pipe.

What is dual plate check valve?

Dual plate check valve are supplied retainerless as standard. – Dual plate Check Valve is possible to prevent water hammering due to closing valve disk by operating the spring in valve before back flow. Also Due-Check valve prevents large piping the for big gap water levels.

What’s the purpose of a check valve?

Check valves are found in almost every industrial application acting as one-way or non-return valves. Check valves are simple devices, perform a vital function by preventing reverse flows, therefore preventing damage and ensuring efficient operations. For example, reverse flow can result in water hammer.

What can a wafer check valve be used for?

Wafer check valves are able to be used in a number of different applications. These include use in chemical processing, power plants, and mining. On a household level, these types of valves are also used in tank inlet/outlet, aquariums, and swimming pools. Are you working on a project in which you need PVC wafer check valves?

What’s the difference between a swing check and a wafer check?

Swing check and wafer check valves have the same function but are very different in design. Their differences commonly dictate what type of situations or systems require which type of valve. Swing check valves use a swinging disc, which is meant to allow or block the flow of materials.

What is the purpose of a check valve?

Check valves are an important type of valve for many industrial and home projects. This type of valve is designed to help prevent backflow within the system as well as maintain a steady level of pressure. Check valves are commonly used to help regulate the flow of liquids and gases.

What is the function of a wafer butterfly valve?

A wafer butterfly valve’s function is to retain a seal to protect against dual-directional pressure differential in the flow of fluid. It is designed for holding a tight seal. Skip to content

What kind of wafer type check valves are used?

The RITAG Type ZRL-HG wafer type swing check valves with external shaft are also used in piping systems across all industrial applications. The model is designed for gaseous and liquid media, under consideration of the maximum differential pressure values. This type is not necessarily the best model for process plant systems.

How is a wafer type butterfly valve installed?

Wafer Types The wafer body is placed between pipe flanges, and the flange bolts surround the valve body. A wafer type butterfly valve is easy to installed but it cannot be used as an isolation valve.

What is the difference between wafer check valve and swing check valve?
