The main performance parameters Temperature: -29 ~ 425 ℃ (steel) -40 ~ + 550 ℃ (stainless steel) Body material:. 304.306.316L Flange: JB / T79. GB913. HG20592 Applicable medium: air, water, steam, oil and nitric acid, acetic acid and other corrosive fluids supply voltage: 220VAC, 24VAC input signal: when 4 ~ 20mA / 1 ~ 5VDC0 ~ 20mA / 0 ~ 10VDC only clear pneumatic valve procurement specifications, categories , work pressure to meet the procurement requirements of the practice, in the current economic environment, the market is imperfect. Because under the pneumatic valve pneumatic valve manufacturers to compete sellers of products, each pneumatic valve were unified design concept, with different innovations, formed their own corporate standards and product personality. Therefore, when the pneumatic valve procurement more detailed technical requirements, coordinating with manufacturers to reach a consensus, as an annex to the pneumatic valve procurement contracts is essential. Pneumatic valve opening and closing levels of the display panel ① pneumatic valve opening and closing degree of scale line should be cast in the gearbox cover or change the direction of the display after the disc casing, all facing the ground Shandong valve, gate valve scale wire brush on the phosphor, to show striking; ② direct needle plate material in the better management of available stainless steel case, otherwise the painting of steel z641f pneumatic valve price, do not use aluminum leather production; ③ direct drive needle eye-catching, stable fixation, once started After closing accurate adjustment, should rivet locked. Pneumatic valve, valve manufacturers Everbright (certified), gate valve is provided by Shandong China Everbright Limited. Valve Co., Ltd. Shandong China Everbright (www.sdgdfm.com) Shandong Weifang, ball leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
