Angle seat control valves
features
ZJHJ pure small pneumatic diaphragm angle single seat regulator uses top oriented structure, equipped with multi-spring actuators. With compact structure and light weight, quick action, fluid passage presents S streamlined and low pressure drop losses, large capacity, high precise flow characteristics, convenient in assembling and disassembling etc. It is widely used in precise control gases, liquids, steam and other media parameters such as temperature, pressure, and flow, liquid level in a given value. Pneumatic diaphragm angle single seat regulator is particularly applicable to small allowed leakage, small pressure differential around valve high viscosity, contain suspended and granular material flow regulation, can avoid coked, jam, convenient to self cleaning and cleaning occasion. Shanghai Yihuan produced pneumatic angle single seat regulator has standard, regulating cutting off, bellows sealing, jacket insulation. Nominal pressure rating has PN16, 40, 64, Nominal diameter scope has DN20-200. Suitable fluid temperature from -200℃ to 500℃ within various grades. Leakage standard level is IV or VI, flow characteristic is linear or equal percentage. Various specifications are available. This product performance index implement GB/T4213-92
