Applications of Dombar Wafer Butterfly Valve 

Dombar is one of the finest wafer type butterfly valve suppliers. Our continuous ingenuity in this field makes us stand out and highly acceptable in the global market for producing first class wafer butterfly valves across many industries.


Our wafer type butterfly valves are in high usage in the LNG industry to ensure proper flow of fluids. Manufactured from Dombor wafer butterfly valve factory, they are also well utilized where high pressure and high temperature are applicable.

Pipeline Industry

Pipelines are used mainly in the transport of fluids. Since valves are manufactured by a certificated wafer butterfly valve manufacturer - Dombor, the media are well controlled and the risk of vibrations and potential clogging is greatly reduced.

Refinery and Petrochemical Industry

In petrochemical industries, clean wafer butterfly valves are of high importance to ensure the crude oil processing isn't hindered or contaminated by slurries.

Wastewater Treatment

As a wafer-type butterfly valve supplier, Dombor manufactures valves that are suitable for smooth wastewater treatment. With this wafer-type butterfly valve, there won't be any form of contamination.

Marine and Ship

Our wafer butterfly valve is also useful in areas where high pressure water is in applications. The valves can provide a resistance against high pressure and high temperature media.

Power Generation

In power generation industries, our high resistant and durable wafer style butterfly valves assist in facilitating a better production process. They also reduce the risk of fire outbreak.

Advantages and Disadvantages of Wafer Type Butterfly Valve

Though they are manufactured by a reliable industrial valve company Dombor, the wafer-type butterfly valve has some notable advantages and disadvantages due to objective factors. Below are listed few:


  • Wafer Butterfly valve can be automatic or manual in operation. 
  • Unlike other valves like check valves, gate valves, etc, wafer butterfly valves are more economical. 
  • Simple and compact design, making them easy to operate. 
  • They are easy to clean, repair and install. 
  • Bi-directional or unidirectional fluid flow is allowed.
  • Can be used in slurries and sludge applications. 
  • Light weight, making them easy to handle. 


  • Wafer butterfly valve seals are weak which may cause leakages in cases of high pressure.
  • Based on designs, wafer butterfly valves are prone to choking and cavitation.
  • When the valve is open, the disc remains in the fluid flow path thereby resulting in a pressure drop.
  • Fluid turbulence can influence both the closing and opening of valve discs.

Why Do You Need Wafer Type Butterfly Valves? 

Compared to other valves like the plug valve, wafer butterfly valves are designed to prevent the pressure difference by two fluids flowing in opposite directions.


They are helpful in water systems to prevent backflow of fluid flowing in one direction. You can also use the valve to decrease the rate of fluid flow.

China Wafer Type Butterfly Valve Sourcing Guide

Before sourcing your desired butterfly wafer type valve, you need to know how they work and the various types.

What is a Wafer Type Butterfly Valve?

This is a valve that’s embedded between two pipe ends, which are extended with flanges. The valve bodies are held together with the use of long bolts to put the body in a firm position. Wafer butterfly valves can be used in conditions where either low or high temperature is required. 

Types of Wafer Type Butterfly Valves Available in Dombor

As a one-stop wafer type butterfly valve supplier, Dombor manufactures all types of wafer butterfly valves for your need. These are the various types of wafer type butterfly valves you can easily order in Dombor.

Zero Offset Wafer Butterfly Valves

Zero Offset Wafer Butterfly Valve

This valve has a stem and disk location at its middle. In its working cycle, a seal is created whenever the disk deforms the soft seat. The valve also handles other applications like coatings, chemicals, abrasives, etc.

Double Offset Wafer Butterfly Valves

Double Offset Wafer Butterfly Valve

In the double-offset construction, the stem center offsets from the disk at valve centers. Over-compression and scraping are reduced significantly. This elimination of scrapes also makes it feasible for valves seals to be built from metal.

Triple Offset Wafer Butterfly Valves

Triple Offset Wafer Butterfly Valve

This design prevents the seat and sealing from touching each other in the flow path. The triple offset butterfly valve is used mainly where metal seats and tight shut off are required. 

Components of the Wafer Style Butterfly Valve

The wafer type butterfly valve consists of the following components

  • Body: The body is mainly used to cover the internal parts of the valve. Unlike other components of the valve, wafer style butterfly valve is made of strong metallic materials like brass, stainless steel, carbon steel, etc.
  • Hand wheel: This component uses the external force applied by the operator to start or stop the valve. It is mainly put to use in manual wafer butterfly valves.
  • Stem: The function of the stem is to transfer torque applied on the hand wheel to the disc. It connects the hand wheel to the valve disc.
  • Disc: The disc provides the mechanism which starts or stops the fluid flow. Wafer style butterfly valve provides the power that either opens/closes the handle via the stem. 


How Does a Wafer Style Butterfly Valve Work?

To start a fluid flow, the handwheel is rotated in the anti-clockwise direction through a 90-degree angle. The rotation of the handle therefore causes the stem and disc to make the same rotation.

To close the valve, the handwheel is turned in the clockwise direction causing the disc to rotate and become perpendicular to the pipe. This process shuts off flow through the valve.
