Two Piece Design - Ptfe Pfa Lined Valve

We are manufacturing and exporting huge range of Two Piece Design - PTFE PFA Lined Valves from Indore, Madhya Pradesh, India. One of the most important features of the Hi-Tech Butterfly valve is the stem seal. The pressure to keep the two sealing surfaces together is provided by an upper and lower set of Cup & Cone Packings resulting in a superior stem seal. The elastomer back-up pads behind the liner ensure a tight fit around the disc, giving a bubble tight shut-off at minimum operating torque. The liner gives a wide flange sealing surface.
The liner and disc are the only two valve parts in contact with the medium.
Primary shaft sealing by preloaded contact between disc and liner hub.
Secondary shaft seal by oversizing the shaft diameter in relation to the shaft hole in the liner.
The liner and disc are molded and machined to close tolerances to provide:
Low torque
Less stress and deformation during opening and closing
Elimination of tearing and bunching
An integrated part of the primary and secondary sealing in the shaft area
Optional TFM lining available for extremely demanding applications.
Integral body locating holes to ease installation and to ensure perfect centering of the valve between flanges.
Actuator Mounting flange dimensions according to ISO 5211.
Anti blow-out shaft provision.
