ZJHM Pneumatic Sleeve Control Valve product details

ZJHM Pneumatic Sleeve Control Valve produced and sold by Baigang valve group is a pressure balance type control valve, the use   of sleeve-oriented, pressure-balanced double seal surface valve body,   equipped with multi-spring pneumatic actuator. S-stream   flow was linear, the overall work balance, allowing pressure, flow   characteristics of accurate, low noise characteristics. Especially suitable for large flow, large pressure difference before and after the valve, leaks do not engage in the occasion. This   series of products are room temperature type, high temperature type,   low temperature type, regulation cut off, bellows sealed and other   forms. Nominal   product pressure rating PN1.6,4.0, 6.4,10.0; body diameter range   DN20-300, the fluid temperature -196 ~ + 560 ℃ range of a variety of   grades. Leakage levels are Ⅳ, Ⅴ, Ⅵ. Flow characteristics of a straight line, equal percentage characteristics. A variety of different specifications to choose from.
