ESDV-Pneumatic Shut off valve
performance parameter
The pneumatic cut-off valve adopts a soft sealing structure, designed with working sealing and maintenance sealing, with small operating torque, moderate sealing pressure ratio, reliable sealing, sensitive action, easy hydraulic control to achieve automatic control, and long service life. Pneumatic cut-off ball valves are widely used in industries such as petroleum, chemical, metallurgy, papermaking, pharmaceuticals, electroplating, etc.
Performance parameters of pneumatic shut-off valve:
1. Working pressure: 1.6Mpa to 42.0Mpa;
2. Working temperature: -196+650 ℃;
3. Driving methods: manual, worm gear, pneumatic, electric;
4. Connection methods: internal thread, external thread, flange, welding, butt welding, socket welding, sleeve, clamp;
5. Manufacturing standards: National standard GB JB、HG， American standard API ANSI， British Standard BS, Japanese JIS JPI, etc;
6. Valve body material: copper, cast iron, cast steel, carbon steel WCB、WC6、WC9、20#、25#、 Forged steel A105、F11、F22、 Stainless steel, 304, 304L, 316, 316L, chromium molybdenum steel, low-temperature steel, titanium alloy steel, etc.
The pneumatic cut-off valve adopts fork type, gear rack type, piston type, and diaphragm type pneumatic actuators, with double acting and single acting (spring return).
1. Gear type double piston, with large output torque and small volume;
2. The cylinder is made of aluminum material, which is lightweight and has a beautiful appearance;
3. Manual operating mechanisms can be installed at the top and bottom;
4. The rack and pinion connection can adjust the opening angle and rated flow rate;
5. Optional live signal feedback indication and various accessories for actuators to achieve automated operation;
6 The IS05211 standard connection provides convenience for product installation and replacement;
7. The adjustable screws at both ends allow standard products to have an adjustable range of ± 4 ° between 0 ° and 90 °. Ensure synchronization accuracy with the valve.
