Zhonghuan's HS actuator is a gas over oil actuator that has a control system, and it relys on spring to travel in straight path. It is widely used in petroleum, chemical, metallurgy, food, and other industrials that requires control of valves.
Advantages
  • 1Moveable Structure Design
    A high degree of freedom is allowed when connecting the piston rod and the piston and when connecting the piston and the valve steam. This method can efficiently transfer thrust without pulling force and radial force between the components. This makes the seal life longer and the actuator work smoother.
  • 2Connection Leakproof Structure
    Piston and piston rod are sealed in series by collaborative sealing method. This way there is zero leakage in various pressure levels and temperature ranges. This product can be used long-term without enery supplement. Quality sealing structure and excellent material make the overall seal resistance very small.
  • 3High-performance Spring
    The spring is made of alloy steel, manufactured by hot rolling and forming. Steps of heat treatment are conducted to achieve stable rigidity and fatigue strength improvement as well as long term loading without any deformation. The surface is electrophoresis-painted with good anti-corrosion property.
  • 4Fine Finishing and Coating
    The actuator's sealing cover is treated with electroless nickel plating and fine grinding, making the actuator wear resistance and corrosion resistance. This way it can work in harsh environment for a extensive period of time.

Zhonghuan's GS actuator is a gas driven actuator that has a control system, and it relys on spring to travel in straight path. It is widely used in petroleum, chemical, metallurgy, food, and other industrials that requires control of valves.
Advantages
  • 1Easily Replaceable Top Shaft Sealing Structure
    The sealing structure between the upper body of diaphragm's house and the top shaft is movable, which facilitates future replacement of seals and actuator maintenance; self-lubricating copper alloy is adopted for top axle sealing to prevent any possible damage on the top shaft surface during operation and transportation; double-layer sealing and dustproof structure are utilized to ensure reliable sealing and dust prevention.
  • 2High-strength Rubber Diaphragm
    The diaphragm is made from high-strength supportive polyester imported from the USA, and was treated with the vacuum vulcanization process. The entire manufacturing process is strictly controlled to improve the cohesiveness of the supporting cloth and sizing material as well as the colloid density, so as to ensure optimum performance and long service life of product.
  • 3High-performance Spring
    The spring is made of alloy steel, manufactured by hot rolling and forming. Steps of heat treatment are conducted to achieve stable rigidity and fatigue strength improvement as well as long term loading without any deformation. The surface is electrophoresis-painted with good anti-corrosion property.
  • 4Stainless Steel and Coating Process for Moveable Parts
    The screw joint at upper body of the actuator is made of 304 SST, which can avoid corrosion resulting from damage of the anticorrosive coating when screwing. The top shaft is made from high strength alloy steel via fine grinding process, with nickel plating treatment. It maximized the optimal properties of the product, such as high sustainability when operating and reciprocating continuously, high resistance to impact, and high adaptability to tough working environment.
