product manual

ZJHPFW pneumatic bellows fluorine single seat regulating valve is a top guide structure, compact structure, fluid channel was streamlined S, the pressure drop, flow is large, wide adjustable range. The valve cover by wave pipe thread sealing structure, can completely eliminate the possibility of the process medium leakage from the stem clearance, which is one of the significant characteristics of bellows seal valves. Because the element itself deformation and outstanding aging resistance of the corrugated pipe, completely overcomes the packing seal valves are packing aging and sensitive temperature difference. Secondly, using corrugated pipe packing a double seal structure, better safe reliability. Therefore, it is in the highly toxic, corrosive, obtained the widespread application of automatic control system of radioactive and other rare special medium. The spool oriented area, good vibration resistance, with ZHA/B multi spring actuators, compact structure, large output force.
