ZSPQ pneumatic shut-off valve adopts soft sealing structure. It has small operating moment, moderate sealing pressure, reliable sealing, sensitive action, easy to realize automatic control and long service life. It is widely used in petroleum, chemical, metallurgical, papermaking, pharmaceutical, electroplating and other industries.

Performance parameters of pneumatic shutoff valve：

1. Work pressure: 1.6 Mpa-42.0 Mpa;

2. Working temperature: - 196 + 650 C;

3. Driving mode: manual, worm wheel, pneumatic and electric;

4. Connection modes: internal thread, external thread, flange, welding, butt welding, socket welding, jacket, clamp;

5. Manufacturing standards: GB, JB, HG, API, ANSI, BS, 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.

Pneumatic cut-off valves adopt new series of GT and AT pneumatic actuators, with double-acting and single-acting (spring reset), rack and pinion transmission, safe and reliable; large caliber valves adopt series AW pneumatic actuator fork-pulling transmission, with reasonable structure, large output torque, double-acting and single-acting.

1. Gear type double piston with large output moment and small volume;

2. The cylinder is made of aluminium and gold, which is light in weight and beautiful in appearance.

3. Manual operation mechanism can be installed at the top and bottom.

4. Rack connection can adjust opening angle and rated flow rate.

5. Actuators can choose live signal feedback instructions and various accessories to achieve automatic operation.

6. IS05211 standard connection provides convenience for installation and replacement of products.

7. The adjustable range of standard products at 0 and 90 can be achieved by adjusting the screw at both ends. Ensure synchronization accuracy with valve.
