Product Description

Soft Seated Concentric Butterfly Valve

The electric Soft Seated Concentric Butterfly Valve is consisted of valve body, valve disc and soft sealed valve seat. Capable of cutting off the medium, the concentric butterfly valve is generally used for the medium like water, oil, gas and other fluid with the temperature less than 80℃.

Key Benefits

The valve body of the wafer butterfly valve is symmetric by the center line, making installation easy and convenient.
Manufactured with PTFE, NBR or other high-quality materials, the valve seat is secure and offers excellent leak-proof performance.
Integrated valve stem structure provides higher strength and prevents medium leakage effectively.
Precise polished valve disc matches perfectly with the seat for outstanding sealing performance.
Large size manufacturing capabilities available.

Frequently Asked Questions

What causes leakage at the stem extension?

There are two main reasons: sealing ring damage, or sealing ring wear and aging. The solution is to replace the sealing ring.

What causes leakage at the valve and pipe connection?

This can be caused by a damaged or contaminated sealing surface, gasket failure, or uneven pressure on the pipe flange.

How do I handle leakage at the connection of the valve and pipeline?

You can repair the sealing surface, clean any dirt, replace the gasket, or ensure the flange bolts are pressed evenly.

What causes internal leakage in the valve?

Internal leakage is usually caused by debris on the sealing surface or damage to the sealing pair itself.

How should internal leakage be resolved?

Remove any debris from the sealing surface and proceed to repair or replace the sealing pair as needed.

What if the valve opening and closing is not flexible?

This is often due to actuator failure or foreign objects blocking the valve plate. Repair the actuator or remove the blockage carefully.
