A, ZJHP / M fine small pneumatic diaphragm valve Product Overview
ZJHP / M fine small pneumatic diaphragm valve driven by the top structure, equipped with multi-spring actuator. With a compact, light weight, sensitive, fluid channel S streamlined, small pressure loss, valve capacity, flow characteristics of precision, and easy disassembly. Widely used for precise control of process parameters gases, liquids and other media, such as pressure, flow, level maintained at a given value. Particularly applicable to allow the leak is small and the differential pressure valve is not in the workplace.
Small air film refined through single seat, the sleeve valve series has standard small air film refined through single seat, the sleeve valve, adjustment cut-off small air film refined through single seat, the sleeve valve, bellows seal type small air film refined through single seat, the sleeve valve, jacket insulation type small air film refined through single seat, the sleeve adjustment and other species. Nominal grade products have PN16,40,64; nominal diameter range DN20 ~ 300. For the liquid temperature from -200 ℃ to + 560 ℃ within the scope of various grades. Leakage standards or grade Ⅳ Ⅵ level, flow characteristics such as linear or equal percentage. Specifications to choose from a wide variety of character.
