  3. Actuator Body
    The extruded cylinder body is made of high quality aluminum alloy with fine machined socket and hard anodized outer surface (anodisation would be provided at special occasion + teflon coat) to prolong the service life and lower the coefficient of friction.
  4. End caps
    Die-casting aluminum surface with metal powder painted in different colours, or sprayed in PTFE or nickel plated.
  5. Pistons
    The twin rack pistons are made from high quality die-casting aluminum treated with hard anodized, symmetrical mounting position, rapid operation, impact resistance, wear resistance, long service life, simply reverse the piston can change the rotation direction of pinion.
  6. Travel adjustment
    The two independent external travel stop adjustment bolts can adjust ±5*at both open and close directions easily and precisely.
  7.  High performance springs
    It has a strong corrosion resistance and service life by use high-quality imported materials, coating processing, pre-pressure assembly, which can be demounted single acting actuator safely and conveniently to satisfy different requirements of torque by changing quantity of springs.
  8. Bearings&Guides
    Made from low friction, long-life compound material to avoid the direct contact between metals.The maintenance and replacement are easy and convenient.
  9. Seals
    NBR for standard temperature, for high and low temperature applications use Viton or Silicone.
  10. Fasteners
    All the fasteners are made of stainless steel for long-term anti-corrosion.

Parts and material

Technology and characteristics

JHA series rack and pinion type pneumatic actuator with high quality, low friction 1 long use life, the open and close time can reach more than 1 million times, high stability.

JHM series declutchable manual override gear operator

Our company’s JHM series part rotary clutch type manual override is widely used lor pneumatic ball valve which is rotated 90°, butterfly valve and plug valve in the system installation, commissioning, and when the system loses gas and powder, it will be converted into a manual operation device. The JHM series manual clutch worm gearbox also has a security control function of the total gas source, and the valve control can be operated much safer. This is an indispensable part of the pneumatic valve control system. It’s designed and manufactured according to the IS05211 standard, with a reasonable structure and reliable performance.

  • Totally-sealed box, internal is based on the grease filling to make the useful life of worm gearbox longer.
  • Protected steel input shaft (stainless steel is for your option)
  • There are ductile iron, WCB, stainless shell for option, durable structure.
  • Stroke: 0-90° mechanical limit.
  • Convenient conversion, lift the limit pin, rotate eccentric device 100°, limit pin limit automatically to achieve pneumatic; on the contrary, to manual.
  • It can be installed with total gas safe control function and cut off the air source and exhaust automatically.

Working environment instructions:
Shell protection ordinary type: IP65 seal, applicable to the standard environment. The special environment can be customized to IP67 and IP68.
Temperatute standard: -20°C~+80°C
Low temperature: -40°C~+80°C
High temperature: -20°C~+120°C

Surface: Special coating (for option) suitable in extreme working environments and marine environments.

JHM series declutchable manual override gear operator

  • Double acting actuator: Control valve opening and closing.
  • Single acting actuator (Spring return): When air or power is cut-off or broken, the actuator will close or open the valve automatically.
  • Double control solenoid valve: When a coil is energized, the valve opens and the other coil turns off the valve when power is applied. With memory function (can be used for explosion-proof).
  • Limit switch box (MONITORING SWITCH): Remotely passes the signal of the valve’s opened and closed status (available for explosion-proof).
  • Mechanical positioner: According to the air pressure to control the valve medium flux (available for explosion-proof).
  • Intelligent positioner: Through the system set the valve position signal, after the calculation process of the control software, thus controlling the intake and exhaust of pneumatic actuator, drive valve position to the set point.
  • Clutch type manual valve actuator: Able to use manual operation for opening and closing valve in the event of loss of air or power.
