Piston Gate Valve

A plunger gate valve refers to a valve whose body shape is similar to that of a gate valve. The sealing effect of a plunger gate valve is achieved by the tight fit between the plunger and the sealing ring, with a large sealing area and almost no wear on the contact surface. When closed, the plunger is inserted into the lower sealing ring to cut off the flow channel, and the medium pressure and resistance during opening and closing are relatively small. Piston gate valves are suitable for applications that require frequent operation and flow regulation, such as food, pharmaceutical, chemical, and other industries. But its adjustment stroke is long and throttling control is difficult, but the valve opening torque is small and can be quickly opened and closed.. The plunger gate valves produced by Shanghai Meiyanyi Pump Valve are mainly made of cast steel, cast stainless steel, etc., consisting of valve body, valve cover, valve stem, plunger, hole frame, sealing ring, handwheel and other components. The sealing rings of plunger gate valves are made of new non-metallic materials, with good mixed comprehensive performance and the ability to withstand long-term high temperature and high pressure without losing elasticity.
