<sup>Immerse yourself in the remarkable capabilities of the 1-X400 series linear stroke piston-type pneumatic actuators. These cutting-edge actuators boast the utilization of cold-drawn hydraulic pipes as their robust cylinder bodies. Subjected to meticulous honing and extrusion processes, they significantly minimize the wear and tear of dynamic sealing elements, thereby dramatically enhancing the actuator's endurance and longevity. Compared to their membrane-type linear stroke counterparts with similar specifications, the 1-X400 series offers superior thrust, showcasing a simple yet sophisticated structure, an elegant lightweight design, and a compact form factor. They epitomize the pinnacle of high-performance pneumatic linear stroke actuators.

The versatility of the 1-X400 series is evident with their availability in both double-acting and single-acting configurations. Seamlessly integrating with linear stroke valves, they are adept at regulation as well as on-off control. When partnered with an array of accessories such as pneumatic control valves, quick exhaust valves, and pneumatic actuators, these actuators masterfully achieve rapid cutoffs, offering precision-cutoff times of 1S, 2S, 3S. and 4S, along with other precise intervals.</sup>

Experience the efficiency of Single-action (S.A.) actuators, featuring a spring-opposed piston activated by air pressure. They deliver the essential benefit of a straightforward fail-safe action. In scenarios where air pressure fails, the compressed spring load effortlessly surpasses the pressure load, effectively moving the stem to open or to close the valve port as per the required fail-safe action, ensuring unwavering stability even when the load on the plug fluctuates.

 

 

 

Conversely, while comparing with double-action (D.A.) actuators, it is notable that S.A. actuators exhibit lower net thrusts. However, their overall dimensions expand in proportion to the increase in supplied air pressure and required stroke.

Double-action actuators with return spring present a commendable balance: where the complete thrust of air pressure on one side of the piston is effectively counterbalanced by a combination of a compressed spring and air pressure on the opposite side of the piston. To achieve a fail-safe action, there is no requirement for complicated and less reliable pneumatic apparatus, and, furthermore, the net thrust of air pressure is merely partially diminished by the spring thrust, ensuring efficiency and reliability.

DESIGN DETAILS

PRESSURE/TEMPERATURE RATING
Our Reliable Pneumatic Piston Actuator is a robust and meticulously engineered choice for industrial applications. Rated to handle a supply pressure of 8 bar, this actuator ensures uncompromising performance and seal tightness. For your peace of mind, every unit undergoes rigorous hydrostatic testing at 10.5 bar before reaching you. Designed for consistent service, the temperature limits at 8 bar are detailed in our table of materials, ensuring reliability in diverse environments.

ACTUATOR BODY
The actuator's cylinder is crafted from a precision steel tube, ensuring durability and precision.
Its interior is enhanced with meticulous lapping, chromium plating, and polishing, providing superior resistance to wear.
Our actuator heads, available in both aluminum and steel cast, offer versatility in design. These heads are offered in various configurations to align seamlessly with your specific valve assembly needs,

featuring options for pivoting assemblies with a fork on either the upper or lower head, ideal for actuating butterfly valves.
Alternatively, a flange design is available to ensure a sturdy and resilient assembly on valve yokes, particularly beneficial for actuating globe or angle valves.

PISTON
Crafted from high-strength steel, our piston is built to endure, equipped with one (S.A.) or dual (D.A.) rubber sealing rings and complemented by two (S.A.) or a single (D.A.) loaded-Teflon guiding skid, ensuring optimal performance and longevity.

STEM
The actuator stem, precision-machined from stainless steel, is meticulously ground, rolled, and threaded for maximum durability and seamless connectivity. A two-piece, bored and threaded block securely clamps the actuator and valve stems, ensuring unwavering performance.
Guided by a dual bronze bushing, the stem is equipped with a felt ring for cleaning and a robust sealing ring (excluding S.A. direct-acting actuators) to effectively prevent leakage, guaranteeing operational integrity.
