Product Description

Specifications

You can rest assured to buy Taian Worm Gear U-Type soft Seal butterfly Valve from our factory.The valve body cavity and the inner lining of the valve disc of this butterfly valve are made of plastic or other inner lining materials with a thickness of 2.5 to 3mm, which are resistant to acids, alkalis and strong corrosion. Due to the small eccentricity between the center of the valve and the rotation center of the valve disc, and the soft seal on the contact surface of the plastic liner, the sealing effect is good. The Worm Gear U-Type soft Seal butterfly Valve structure adopts an adjustable sealing surface, which has a long service life and solves the problem of easy leakage of traditional butterfly valves.
