ZJHPW bellows sealed pneumatic single-seat control valve for
industrial process automation control system. It can automatically turn
on or off when receiving the electric control signal, so as to realize
the on-off or flow control of the fluid in the pipeline. This series of
solenoid valve can be widely used in the production and R & D
departments of textile, printing, chemical, plastics, rubber,
pharmaceutical, food, building materials, machinery, electrical
appliances, surface treatment and other facilities for people's daily
life such as bathrooms, canteens and air conditioners. ZJHPW bellows
sealed pneumatic single-seat control valve is mainly used for corrosive
liquids, clean liquid and edible liquid medium control.

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.
