 Second, ZJHPW bellows pneumatic single-seat control valve seal Features Description

ZJHPW bellows sealed pneumatic single-seat control valve, is a top-oriented structure of the control valve, compact body structure, the flow was S-streamline pipeline, pressure loss loss, flow, adjustable wide range. 
 The bonnet seal structure with corrugated pipe can completely eliminate the possibility of leakage of process media from the stem movement gap, which is one of the notable features of the bellows sealed valve. Due to their inherent deformability and outstanding aging resistance, the bellows valve completely overcomes the filler weathering and temperature-sensitivity issues commonly associated with packing valves. Second, the use of double bellows - packing seal structure, better safety and reliability. Therefore, it is widely used in the automatic control system of rare special media such as highly toxic, corrosive, radioactive and so on. Large spool guide area, good vibration resistance, with multi-spring film actuator, its compact structure, the output power.
