Pneumatic diaphragm tee confluence,shunt control valves
Features
ZJHH, ZJHF pneumatic diaphragm tee confluence regulator and pneumatic diaphragm tee shunt regulator use cylinder thin-wall windows core oriented structure, different from plunger core lining guidance. Equipped with multi-spring actuators. With compact structure and light weight, quick action, convenient in assembling and disassembling etc advantages. It is widely applied in gases, liquids etc. Precise control of process parameters on the medium pressure, temperature, flow rate and fluid in a given value. Shanghai Yihuan produced this type product is suitable for taking one fluid through tee valve divide into two way outflow, or take two fluid through tee combine one fluid occasions. Pneumatic diaphragm tee confluence, shunt control valve has tee confluence and tee shunt. Nominal pressure has PN16, 40, 64, nominal diameter scope is DN25-300. Suitable fluid temperature from -60℃ to 560℃. Leakage standard is class IV. Flow characteristic has linear and papabola. This product performance index implement GB/T4213-92
