Product Description

ZH Series Cylinder Linear Actuator
The AM-type actuators utilize spring-balanced diaphragm actuators that respond to pneumatic output signals from the valve positioner applied to the actuator  diaphragm. The position of the valve plug inside the valve is determined based on signal variations.The zero position setting of the actuator is determined by the compression amount of actuator spring, and the travel range is determined by the stiffness of actuator spring.The AM857 actuator is positive-acting, and the AM867 actuator is reverse-acting.These designs enable reliable on-off operation or throttling control of the valve.
Specification
1.Wide thrust range:
ZH series double-acting actuator can provides the maximum output thrust-2,000,000 N, the single-acting actuator can offer the maximum output thrust - 300,000 N (working pressure rang is 3 ~ 7 bar).
2.Multiple manual mechanisms:
ZH series actuator is equipped with a variety of manual  mechanisms to meet user's requirements, including: top screw manual, top latch manual, top side mounted turbine manual, top side mounted bevel gear manual, middle side mounted bevel gear manual, hydraulic manual and  fully sealed bevel gear side mounted manual.
3.Customized connection size:
Our pneumatic linear actuators can be customized with flange sizes that match the valves as needed, which is convenient for users to install, disassemble and replace.
4.Inner pull rod type cylinder design:
The cylinder with an internal tie-rod design features a sleek and elegant  appearance. Under the same bore diameter, its outer diameter is smaller.
Meanwhile , the internal tie-rod provides support and guidance to the piston preventing uneven wear of the cylinder, ensuring smoother operation and extending service life.
5.Standard spring design:
For valves of different types and pressure, we customize springs that meet   the specific thrust force and stroke requirements for each individual valve.
Additionally, a standardized spring library is designed for commonly usedvalves and calibers.
6.Working environment:
High-quality sealing rings are used in both pneumatic and manual actuator, achieving class IP67 protection.It can operate smoothly within -70ºC to +250ºC and maintains continuous and stable performance even in harsh environmental conditions.
