Extension bar hard seal butterfly valve-WESDOM Group

Product Introduction

The design principle of an extension bar hard seal butterfly valve is similar to that of a soft seal butterfly valve but with a few key differences.

The hard seal butterfly valve has a metal-to-metal seal or a seal made of materials like PTFE, which provides a more durable seal than soft seals. The metal-to-metal seal is made when the valve is closed, and the disc is pressed against the valve seat with a high degree of force, providing a tight shut-off against the flow medium. The PTFE seal is made of a tough, inert material that can withstand high temperatures, pressures, and corrosive fluids.

The extension bar is attached to the stem to extend the length of the valve handle, allowing the valve to be operated from a distance or in hard-to-reach locations. The stem connects the disc to the valve actuator and allows the disc to be rotated to control the flow of fluid.

The operation of an extension bar hard seal butterfly valve is based on a quarter-turn principle. When the valve actuator is rotated, the disc rotates around its axis to open or close the valve. The metal-to-metal seal or PTFE seal on the disc provides a tight shut-off against the flow medium, reducing the risk of leakage and ensuring reliable performance.

Advantages of extension bar soft seal butterfly valve!

Improved accessibility

The extension bar allows the valve to be operated from a distance or in otherwise hard-to-reach locations, making it easier to maintain and control

the flow of fluid.

W
Enhanced sealing

The soft seal on the butterfly valve provides a tight, reliable seal against the flow medium, reducing the risk of leakage and improving performance.

E
Fast, efficient operation

Butterfly valves are known for their fast-acting, quarter-turn operation, which can help to reduce downtime and increase productivity.

S
Lower maintenance costs

The simple design of butterfly valves means that they are often easier and less expensive to maintain than other types of valves.

D
Versatility

Butterfly valves can be used in a wide range of applications and fluid types, including water, air, gas, and chemicals, making them a versatile choice

for many industries.

O
