Product Description

A wafer butterfly valve is a type of quarter-turn valve that controls the flow of fluids in a pipeline. It is called a "wafer" valve due to its slim, wafer-like profile, which allows it to be sandwiched between two pipeline flanges without the need for additional flange bolts

The wafer butterfly valve consists of a thin, disc-shaped closure element known as the "butterfly" that pivots around a central shaft. The disc is mounted in the center of the valve body and is typically made of metal or a resilient material such as rubber or PTFE.

The valve body is usually constructed from materials like cast iron, ductile iron, stainless steel, or carbon steel, depending on the application requirements.
The valve's slim profile and lightweight design make it easy to install and suitable for use in space-constrained areas.

Compact and Lightweight Design: Wafer butterfly valves have a slim, compact design, making them easy to install and suitable for use in space-constrained areas. Their lightweight construction reduces stress on piping systems and makes them easier to handle during installation and maintenance.

Cost-Effective: Wafer butterfly valves are typically more cost-effective than other types of valves, such as gate valves or globe valves. Their simple design and construction result in lower material and manufacturing costs, making them an economical choice for many applications.

Quick Operation: Butterfly valves operate on a quarter-turn principle, meaning they can be quickly opened or closed with a 90-degree rotation of the disc. This rapid operation allows for efficient flow control and helps minimize downtime during system maintenance or emergencies.
 

 

The operation of a wafer butterfly valve is straightforward: when the valve is in the open position, the disc is rotated parallel to the flow direction, allowing fluid to pass through the valve with minimal resistance.

To close the valve, the disc is rotated perpendicular to the flow direction, effectively blocking the flow of fluid through the pipeline.

Wafer butterfly valves are an essential component in many different types of piping systems. They provide efficient and reliable performance while also being relatively easy to install and operate. Understanding the basics of how they work and the features they possess will help you choose the right wafer butterfly valve for your application. Additionally, it is important to follow proper maintenance practices to ensure that your valve offers maximum performance and reliability. With regular inspections and proper operation techniques, you can get the most out of your wafer type butterfly valve for a long time to come.
