Electric three-eccentric metal hard seal butterfly valve-WESDOM Group

Product Introduction

The design principle of a three-eccentric metal hard seal butterfly valve is based on the offset nature of the valve seat from the centerline of the valve shaft. The valve seat is offset in three different directions, which creates a seal that is not subject to wear and tear, even after prolonged use.

When the valve is in the closed position, the metal hard seal creates a tight seal around the valve seat, preventing fluid from passing through. When the valve is in the open position, the disc rotates around the shaft to allow fluid to pass through the valve.

The three-eccentric design of the valve also reduces the friction between the disc and the valve seat, which helps to extend the valve’s life and reduce the torque required to operate the valve. This makes the valve more efficient and easier to operate than other types of valves.

The electric actuator on the valve allows for remote operation of the valve, making it ideal for applications where manual operation of the valve is not practical or safe. The electric actuator can be programmed to open or close the valve at specific times or in response to specific conditions, providing greater control over the flow of fluids in a pipeline.

Advantages of three-eccentric metal hard seal butterfly valve!

Reduced friction and increased valve life

A double eccentric butterfly valve has two points of contact between the disc and the valve seat, creating a seal when the valve is closed. This design reduces the amount of torque required to operate the valve and increases the valve’s service life. However, the double eccentric design is prone to wear and tear over time, which can cause leaks and reduce the efficiency of the valve.

W
Less prone to leakage

On the other hand, a three-eccentric metal hard seal butterfly valve has three points of contact between the disc and the valve seat, which creates a seal that is not subject to wear and tear. This design allows the valve to maintain a tight seal even after prolonged use, which reduces the risk of leaks and enhances the efficiency of the valve.

E
Better suited to high flow, high pressure, and corrosive service conditions

Another difference between the two types of valves is in their applications. Double eccentric butterfly valves are typically used in applications where moderate to high flow rates are required, while three-eccentric metal hard seal butterfly valves are used in applications where high flow rates, high pressure, and/or abrasive or corrosive fluids are present.

S
Corrosion-resistant

The valve is made of high-quality materials such as stainless steel or titanium, making it highly resistant to corrosion and suitable for use with corrosive fluids.

D
Remote operation

The electric actuator on the valve allows for remote operation of the valve, making it ideal for applications where manual operation of the valve is not practical or safe.

O
High flow capacity

The valve’s disc is designed to rotate around the shaft, allowing for high flow rates and low-pressure drops, making it ideal for applications requiring high flow capacity.
