<sup>The innovative 1-X400 series linear stroke piston-type pneumatic actuators are designed with precision and durability in mind. Crafted using cold-drawn hydraulic pipes as cylinder bodies, and enhanced through honing and extrusion processes, these actuators effectively minimize wear on dynamic sealing elements, ensuring exceptional longevity. Compared to traditional membrane-type linear stroke actuators of the same specifications, the 1-X400 series offers superior thrust power. With their simple structure, lightweight design, and compact form, these actuators represent the pinnacle of high-performance pneumatic linear stroke technology.

The versatile 1-X400 series actuators are available in both double-acting and single-acting configurations, offering flexibility for various applications. Perfectly paired with linear stroke valves, they are ideal for both regulation and on-off control purposes. When equipped with essential accessories such as pneumatic control valves, quick exhaust valves, and pneumatic actuators, they enable rapid cutoffs with precision, featuring cutoff times as swift as 1S, 2S, 3S, and 4S, along with other levels to suit your operational needs.</sup>

Single-action (S.A.) actuators operate through a spring-opposed piston actuated by air pressure, providing a reliable fail-safe action. In the event of an air pressure failure, the pre-compressed spring load triumphs over the pressure load, seamlessly moving the stem to open or to close the valve port as per the required fail-safe action. This design ensures excellent stability, even when the load on the plug varies.

 

 

 

In contrast, while double-action (D.A.) actuators exhibit lower net thrusts, their overall dimensions expand with the increase of supplied air pressure and required stroke. Yet,

double-action actuators with return spring present a balanced solution: the full thrust generated by air pressure on one side of the piston is ingeniously countered partly by a compressed spring and partly by the air pressure on the opposite side of the piston, ensuring a balanced and efficient operation. Therefore, achieving a fail-safe action does not demand complicated or unreliable pneumatic apparatus. Additionally, the net thrust of air pressure is only marginally affected by the spring thrust, preserving operational efficiency.

 

Product Description

DESIGN DETAILS

PRESSURE/TEMPERATURE RATING
The actuator is crafted to endure a rated supply pressure of 8 bar for both the cylinder and the sliding seals' tightness. Prior to delivery, each actuator undergoes a rigorous hydrostatic test at 10.5 bar, ensuring unparalleled reliability. The temperature limits for continuous operation at 8 bar are meticulously outlined in the materials table, offering clarity and assurance for sustained performance.

ACTUATOR BODY
The cylinder is expertly manufactured from a high-precision steel tube, ensuring strength and durability.
Its interior is meticulously lapped, then enhanced with chromium plating and polished to perfection.
The actuator features dual-headed designs, available in robust aluminium or steel cast. These heads come in various configurations to seamlessly integrate with assorted valve assemblies or operational needs,

including a fork on either head for pivoting assemblies, such as for actuating butterfly valves.
Additionally, a flange option is available for secure assembly on valve yokes, ideal for the operation of globe or angle valves.

PISTON
Crafted from high-strength steel, the piston is equipped with either one (S.A.) or two (D.A.) durable rubber sealing rings, and complemented by two (S.A.) or one (D.A.) precision-loaded Teflon guiding skid.

STEM
Forged from a stainless steel rod, the meticulously machined stem is ground, rolled, and threaded at the external end. For unmatched precision, the actuator stem links with the valve stem via a sophisticated two-piece, bored and threaded block, ensuring a firm grip on both screwed ends.
Guided by a dual bronze bushing, the stem is further supported by a felt ring for thorough wiping, alongside a sealing ring (except in S.A. direct-acting actuators) to proficiently prevent any leakage.
