PFA Lined Gate Valve
GMK PFA Lined Gate Valve is a kind of gate valve known as a "rising stem gate valve" one in which the disc of the gate valve moves upward in the same direction as the valve stem. The term "rising stem gate valve" is used to describe this kind of gate valve. A gate valve is said to have a "non rising stem gate valve" when the stem may be twisted without causing the disc to rise upward in a straight line. The stem nut for this kind of gate valve is located in the disc that the gate valve consists of. The dead-clamp phenomenon, which was previously caused by the presence of a medium consisting of particles and fiber on the interior of a screw non-rising stem-type gate valve, has been eradicated.
