Product Description

Wafer Butterfly Valve is a rotary type valve with a visual indication of whether the valve is in a fully open position or not.

Butterfly valves are commonly used in fire protection systems as system control valves, sectional or pump water control valves. These valves have been designed with minimum flow restriction and pressure loss when in fully open position.

To reduce the risk of a water hammer Rapidrop Butterfly Valves are provided with a slow close hand wheel operation gearbox.

 

• Available in Wafer Pattern with NBR (Buna) liner, in sizes: 2" to 6".
• Locking lever or gearbox operation.
• Temperature range: -10°C to 80°C.
• Pressure rating: PN16 up to 6".

Wafer butterfly valves are used in a variety of piping systems to regulate the flow of liquid or gas between two points. Hey provide efficient and reliable operation by allowing for quick on/off control, as well as precise regulation when necessary. Wafer butterfly valves are relatively simple to install and operate, making them a popular choice for many applications. In this article, we'll explore the basic workings of wafer butterfly valves, different types available, installation tips and more.

These valves are typically installed in pipelines that receive frequent use and must be trusted for reliable performance. Wafer butterfly valves consist of a disc mounted on the end of a stem connected to an actuator such as a hand wheel or motor.

When the valve is opened, the disc swings away from the line, creating an unrestricted path for the flow through the middle of the valve. When closed, the disc's edges come into contact with either side of the line, blocking it off completely. This design helps to ensure tight shut-off without having to install any additional seals or packing materials. The ease of installation and simple design make wafer butterfly valves a popular choice for many applications, providing cost savings over other control valves due to their shorter installation time and low maintenance requirements.

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.
