A gate is introduced:
PZ673X series Pneumatic clamping type knife type gate valve After equipped with electromagnetic valve, proximity switches and other accessories to complete the motion control and the output signal of the opening and closing position, also can complete automatic control of continuous action. The main use of cast iron, cast steel, stainless steel etc.. The path from DN50 to DN1000. Pneumatic valves are widely used in chemical, coal, sugar, water, paper and other fields, is an ideal sealing valve.
Second, the main structure and characteristics:
PZ673X series Pneumatic clamping type knife type gate valve The left and right valve, U type sealing ring, gate, steel nut, stem, frame, cylinder parts, pneumatic valve by the pneumatic cylinder actuators to complete. The use of the folder structure, small size, light weight; completely open access, which can prevent the valve dielectric deposition. The new type U sealing ring, the valve can guarantee a good seal; small flow resistance, easy installation and maintenance. The gate of the outer seal, is embedded in the body through the flexible seal to achieve, and by means of screws, adjust the plate.
