<sup>Introducing the 1-X400 series linear stroke piston-type pneumatic actuators-engineered to perfection with cold-drawn hydraulic pipes serving as robust cylinder bodies. Through meticulous honing and extrusion, these actuators significantly reduce wear on dynamic sealing elements, ensuring unparalleled durability. Compared to their membrane-type counterparts, they deliver unmatched thrust, thanks to their simple structure, lightweight design, and compact size. Experience high-performance like never before with these cutting-edge pneumatic linear stroke actuators.

The extraordinary 1-X400 series is available in both double-acting and single-acting models, providing unmatched versatility. When paired with linear stroke valves, these actuators can perform precise regulation or seamless on-off control. With state-of-the-art accessories like pneumatic control valves, quick exhaust valves, and additional pneumatic actuators, these actuators guarantee rapid, efficient cutoffs with precision timing of 1S, 2S, 3S, and 4S, offering you unparalleled operational efficiency.</sup>

Single-action (S.A.) actuators are ingeniously designed with a spring-opposed piston activated by air pressure. These actuators present the advantage of a straightforward fail-safe action-should air pressure fail, the compressed spring load triumphantly overcomes the pressure load, gracefully moving the stem to either open or close the valve port as per the desired fail-safe operation. This mechanism ensures remarkable stability, even when the load on the plug varies, maintaining consistent performance.

 

 

 

In contrast, double-action (D.A.) actuators are known for their higher thrust capabilities, though their dimensions increase with rising air pressure and stroke demands. Despite this, single-action actuators demonstrate superior adaptability.

Double-action actuators enhanced with a return spring present an ideal balance: the full air pressure thrust on one side of the piston is skillfully balanced by both a compressed spring and opposing air pressure on the other side of the piston, ensuring equilibrium. Achieving a fail-safe action is seamless, eliminating the need for complex and often unreliable pneumatic systems. Furthermore, the net air pressure thrust is only partially reduced by the spring thrust, ensuring powerful performance with reliability and precision.

 

Product Description

DESIGN DETAILS

PRESSURE/TEMPERATURE RATING
Our innovatively engineered actuators boast an 8 bar rating, which is the optimal supply pressure for the cylinder and ensures the uncompromised tightness of the piston's sliding seals. To guarantee peak performance, each actuator undergoes rigorous hydrostatic testing at a pressure of 10.5 bar before it reaches you. The temperature parameters for continuous operation at 8 bar are meticulously detailed in our materials table, ensuring you have all the information for reliable usage.

ACTUATOR BODY
The cylinder is meticulously crafted from a precision steel tube, showcasing our commitment to quality.
The inner surface is expertly lapped, then enhanced with a layer of chromium plating, and polished to perfection for seamless operation.
Our actuator heads, crafted from durable aluminium or steel castings, are thoughtfully designed in a variety of shapes to cater to diverse assembly requirements, whether on valves or for

operating with a fork on either the upper or lower head, ideal for pivoting assemblies such as butterfly valve actuation.
When paired with a flange, they allow for robust assembly on valve yokes, making them perfect for the actuation of globe or angle valves, ensuring versatility and reliability.

PISTON
Crafted from high-strength steel, our piston is equipped with durable sealing rings-one (S.A.) or two (D.A.) rubber rings-and guiding skids made of loaded-teflon-two (S.A.) or one (D.A.)-guaranteeing optimal performance and longevity.

STEM
Our stem, precision-machined from stainless steel, is subjected to grinding, rolling, and threading processes at the exposed end. The actuator stem seamlessly connects to the valve stem via a two-piece, bored, and threaded block, which securely clamps the screwed ends of both stems, ensuring stability.
The stem is precisely guided by a double bronze bushing situated in the lower head, which also houses a felt ring to clean the stem and a sealing ring, except for S.A. direct-acting actuators, to effectively prevent leakage, showcasing our attention to detail.
