Pneumatic knife gate valve detailed description I. Overview PZ673H (X, F) -2.5,6,10,16 series pneumatic knife gate valve is one of my company produced a series of control valves. The product is in production and application process of continuous digestion and absorption of foreign similar product structure and manufacturing process of advanced features, and constantly improve the technological content of products, from some technical details to proceed to improve the overall performance of the valve. The product passed equipped with solenoid valves, proximity switches and other accessories can complete the open, motion control and signal output off two positions, can also be done automatically controlled continuous operation. Users can choose according to actual needs. PZ673H (X, F) series pneumatic knife gate valve varieties. The main use of cast iron, cast steel, stainless steel. Diameter from DN50 ~ DN1000. Our products are widely used in chemical, coal, sugar, water, paper and other fields, is an ideal sealing valve. Particularly suitable for the paper industry in the pipeline to make adjustments and throttling. Second, the main structure and characteristics of the valve consists of left and right body, U-ring, gate, steel nuts, stem, frame, cylinders and other pieces composed by the cylinder valve opening and closing operation to complete. This valve Features: 1, using clip-on structure, small size, light weight. 2, completely open channels that can prevent the deposition of the medium in the valve. 3, the newly developed U-seals, you can ensure a good seal valve. 4, the outer sealing ram, and is embedded in the valve body by an elastic sealing strip is achieved, and by means of screws, to adjust the pressure plate. 5, the flow resistance. 6, easy installation and maintenance. Third, the main part materials No. Part Name Material No. Part Name Material Remark 1 Body HT250 5 bracket Note 1: The rubber grades depends on the medium and temperature. 2: The gate material depends on the medium composition. 2 ring rubber (Note 1) 6 3 gate stainless steel stem (Note 2) 7 Teflon seal nut ZHMn58-2-2 4 8 handwheel QT40-17 four valves optional drive model configuration table 1 cylinder is compressed air as the medium, to convert its energy into mechanical energy, to achieve linear motion device is widely used in various pneumatic actuator system is the basis for industrial automation components.

(2) Use a filter, regulator, lubricator combination (F-R-E combination) to adjust the air quality, increase service life. (3) selection of output greater than the actual load cylinder, to avoid danger is insufficient air pressure. (4) Note the use of ambient temperature within the cylinder and piston ring sealing portions of the material is generally limited to the use of temperature -5 ℃ - within + 60 ℃. (5) a corrosive gas environment, material within the cylinder piston and seal portion, generally use PTFE.
