How much is the price of pneumatic cut-off valve

Pneumatic cut-off valve, also known as the pneumatic cut-off valve, is one of the automation system of actuators, pneumatic diaphragm actuator by a more spring or floating, and pneumatic control valve piston executing agency, receive signals adjusting instruments, fluid control technology of the pipe on the cut, or switch. It has a simple structure, sensitive reaction, reliable operation, etc. Can be widely used in petroleum, chemical, metallurgical and other industrial production. Pneumatic cut-off valve of air required by the compressed air filter, flowing through the valve body is supposed to be free of impurities and particles of the medium of liquid and gas. 1, the piston actuator, operating strength, using the differential; Type 2, balance trims, enhanced the allowable differential shut-off valve; Part 3, trim seal has tight and soft seal two kinds, tight type for carbide surfacing, soft seal type for soft materials, closed, sealed performance is good; 4, the body structure has a single seat, sleeve, two-seat ( Two three links) Three, sealed form has two kinds of packing seal and bellows seal, the nominal pressure level products are PN10, 16, 40, 64 four, nominal diameter range 3/4 '~ 200 mm. Apply fluid temperature by - 60～450℃。 Leakage of grade IV level or Ⅵ level. Flow characteristic of quick opening; 5, the valve body according to the fluid mechanics principle designed to uniform the low flow resistance of fluid, rated flow coefficient increases by 30%; 6, adopt more spring actuator and regulating mechanism with three columns are linked together, the whole height is reduced by about 30%, the weight can reduce about 30%; 7, to the movement of the valve stem form completely sealed, blocking off the possibility of leakage of medium. Zhejiang flying Wolf automatic control instrument co. , LTD. Of pneumatic cut-off valve is the most preferential price, welcome to buy.
