Pneumatic cut-off valve product price expensive?

Pneumatic cut-off valve product price expensive? Pneumatic cut-off valve, pneumatic cut-off valve categories: normal rapid emergency pneumatic cut-off valve. Products are constantly updated, and with the development of science and technology, the performance of the product been improved greatly, and now the product can meet the demand of people to a great extent. The price of the product? These needs according to each manufacturer to product production, and so on and so forth to locate. Advantages of pneumatic cut-off valve 1, 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; More than 2, the 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%; 3, the body according to the fluid mechanics principle design into the low flow resistance of fluid, cross section of the rated flow coefficient increases by 30%; Part 4, trim seal has tight and soft seal two kinds, tight type carbide surfacing, as soft seal type for soft materials, closed sealed performance is good; 5, balanced trims, enhanced the allowable differential shut-off valve; 6, bellows seal type of mobile stem form completely sealed, blocking off the possibility of a medium leakage; 7, piston actuator, operating strength, using differential pressure is big. Warm prompt: the birth of pneumatic cut-off valve products brought a lot of convenience to human life, and the product is not static, but with the development of science and technology innovation constantly. Today, the manufacturer of the product all over the country, choose a suitable manufacturer is the need to work.
