ZSQN piston pneumatic three-way shut-off valve, the
ZS-type spring piston actuator and the shut-off valve, small size and
light weight, cut off quickly and reliably, allowing the pressure
difference. It is the executive component of
automatic control system. It takes two regulating instruments, PC
program-controlled machine and electronic control ON-OFF switch signal
to cut off, turn on or change the medium flow direction, realize the
two-way control of process parameters, suitable for process pipe
Emergency cut off and vent with automatic protection interlock system
and other places. This series of products are film, piston two. The
valve body structure has a single seat, sleeve, two seat (two three)
three, the sealing form of packing seal and bellows seal two. Has
the advantages of simple structure, large operating force, small size,
light weight, small flow resistance, large valve capacity, good sealing
performance and convenient maintenance. For non-granular, non-impurity gas, liquid medium, requiring close close fast, quick emptying of the automatic control system. Widely
used in petroleum, chemical, metallurgy, electric power, textile and
other production processes in the automation and control systems.
ZSQN-type pneumatic piston three-way shut-off valve main performance parameters
Type: Pneumatic Piston Actuator
Supply pressure: 0.4-0.7MPa
ZSQN-type
pneumatic piston three-way shut-off valve Type of action: gas or gas
off (the role of three-way shut-off valve The way is on the valve seat,
the air is the side of the open at the end of the valve, the valve is
the role of the implementing agencies. On the other hand, the gas off
the side of the closed at the end.)
Sealing material: PTFE, stainless steel, etc.
Flow characteristics:
Leakage: Metal seat: less than 0.01% of the valve rated capacity, in line with GB / T4213IV-class
soft seat: less than the rated capacity of the valve 10-7, in line with GB / T4213V level
cut off time: 0.5-4 seconds
