VPVL200 Pneumatic Actuator, VPVL200 Pneumatic Butterfly Valve, The VPVL series double-piston pneumatic device offers advantages such as long operational life, robust structure, symmetrical and compact design, and a wide selection range. It is specifically designed for the quick and efficient operation of ball valves, butterfly valves, and other rotary valves.

Versatile and highly adaptable
● Utilizes modular design; double-acting and spring-return pneumatic devices share the same body and end covers, reducing inventory. Springs can be temporarily added, ensuring on-site conversion from double-acting to spring-return or adjustment of air supply pressure.
● The fail-safe direction can be easily changed by simply reversing the piston, i.e., converting from spring-open to spring-close, or vice versa.
● The connection between the actuator and the valve complies with ISO 5211/1.
● Solenoid valves and accessories are compatible with NAMUR VDI/VDE 3845.
● To meet various automation needs of valves, a wide range of accessories and control components are available, including limit switches, solenoid valves, and positioners.
Long operational life
● Bushings support sliding and rotating components to ensure extended service life.
● The double-piston rack and pinion mechanism features a simple structure, easy installation, long life, and consistent torque output.
● The extruded aluminum housing with plating and finely ground inner cavity surface provides high strength and low friction coefficient.
● The multi-guided aluminum piston operates precisely with minimal friction and long lifespan.
● The rack and pinion are precision-machined, ensuring excellent gear engagement and high efficiency.
Excellent corrosion resistance
● The end covers are coated with a polymer, springs are epoxy-coated, and stainless steel fasteners are used both internally and externally, ensuring corrosion resistance in various challenging environments and conditions.
