What is resilient seated butterfly valve?


The butterfly valve is also called the seated butterfly valve. This butterfly valve is essential for water treatment and industrial water supply, and it is widely used in many industries. The seated butterfly valves are designed with PE (polyethylene), PVDF (polyvinylidene fluoride), or PFA (perfluoroalkoxy) materials, and they can be used for both high temperature and pressure applications. First of all, let’s talk about what is this product? This product is a resilient seated butterfly valve. What is its definition, working principle, advantages, and disadvantages? Where is the application?

Definition of the resilient seated butterfly valve:

A resilient seated butterfly valve is a valve that opens and closes by means of a spring-loaded disc. The disc is held closed by a spring, but when the valve is opened, the disc springs back open. This type of valve is commonly used in industrial applications because it requires little maintenance and can handle high pressures.

Resilient seated butterfly valves are similar to poppet valves, which are also used in industrial applications. However, instead of having a ball that moves up and down inside the body to open and close the valve, resilient seated butterfly valves have a disc that moves up and down inside its sleeve.

This design allows for higher pressures than poppet valves, but they can be restricted by debris or dirt build-up on the surface of the seating area or on the face of the piston head.

Working principle of the resilient seated butterfly valve:

A seated butterfly valve is a valve used to control the flow of fluid through a system.

A seated butterfly valve is a positive-acting, direct-operating, quarter-turn valve. It has a stem that fits into a guide rod in the valve body, which rotates on a shaft that is part of the valve body. The valve is mounted on one side of the pipe or tubing and is opened and closed by turning approximately 90 degrees, or a quarter turn. When the handle is turned in one direction, the valve opens by lifting the disc out of its seat ring. The disc is then lifted from its seat while allowing fluid to flow through the opening between it and the valve body. After rotating 90 degrees, the disc will fall back onto its seat, sealing the flow through the device. A seated butterfly valve can be used as an isolation device or as part of an assembly through which fluid must pass at some times and not at others (such as in an isolation/balancing system).

Advantages of the resilient seated butterfly valve:

The Resilient Seated Butterfly Valve is a compact, self-sealing, non-rising valve designed to close off flow through a pipe in two directions under pressure. It is used for the isolation of hazardous or contaminated equipment and for isolation during maintenance or repair.

The Resilient Seated Butterfly Valve offers many advantages over other types of valves.

1. Easy to install: The Resilient Seated Butterfly Valve requires no special tools for installation. It can be installed using hand tools or power tools depending on the application and budget. In addition, the valve can be installed by operators without extensive training.

2. Reliable: The Resilient Seated Butterfly Valve is designed specifically for hazardous environments and will not fail unless subjected to extreme external forces such as impact or crushing. The butterfly element is also resistant to chemicals and corrosion that may occur in your process environment.

3. Compact design: The Resilient Seated Butterfly Valve has an extremely compact design that allows it to fit into tight spaces while still being able to handle high pressures up to 15000 psi (1000 bar). This makes it ideal for use on small diameter piping systems where space is limited or where there are multiple valves needed at once in order to control.

Disadvantages of the resilient seated butterfly valve:

A disadvantage of the seated butterfly valve is that it can be difficult to install. This type of valve is usually installed in place by first drilling a hole through the pipe and then inserting the stem of the butterfly valve into the hole. The stem is then held in place by a set screw on top of the valve. In order to make sure that this type of butterfly valve installs properly, you must make sure that there are no obstructions around it.

The main disadvantage of this type of butterfly valve is that it cannot be used for applications where there will be high temperatures or pressures involved. This type of butterfly valve may also not be suitable for liquids that have a high viscosity because they will not flow easily through them due to their design.

Application of the resilient seated butterfly valve:

The seated butterfly valve is a pneumatic actuator that is used in control systems. The seated butterfly valve is used in various fields such as HVAC, refrigeration, air conditioning, heating and air conditioners, aerospace, military, and defense applications.

The seated butterfly valve is mainly used for regulating the flow of gas or liquids through an opening in the process line. It can also be used for controlling the flow of gases when it comes to maintaining pressure and temperature in a system.


Resilient seated butterfly valves are double-seated valves that can be either single flow or double flow. They are designed to provide high resistance to leakage, and they have three or four seats on each side of the disc.
