<sup>The 1-X400 series linear stroke piston-type pneumatic actuators from SNT Machinery (Qingdao) Co., Ltd. stand out with their advanced engineering. Utilizing cold-drawn hydraulic pipes as cylinder bodies, and enhanced by honing and extrusion techniques, these actuators significantly minimize wear on dynamic sealing elements, ensuring exceptional durability. Compared to membrane-type counterparts of similar specifications, they boast superior thrust. Their design is simple yet sophisticated, lightweight, and compact, making them a formidable choice in high-performance pneumatic linear stroke actuators.

Featuring options for both double-acting and single-acting configurations, the 1-X400 series linear stroke piston-type pneumatic actuators provide versatile functionality. When paired with linear stroke valves, they excel in applications for regulation or on-off control. With the addition of accessories such as pneumatic control valves, quick exhaust valves, and pneumatic actuators, these systems can achieve swift and efficient cutoffs, offering cutoff times as rapid as 1S, 2S, 3S, and 4S, accommodating various operational requirements.</sup>

Single-action (S.A.) actuators are ingeniously designed with a spring-opposed piston activated by air pressure, ensuring a straightforward fail-safe action. In the event of air pressure loss, the compressed spring load dominates, moving the stem to open or close the valve port as needed, providing excellent stability even when the load on the plug fluctuates, maintaining reliable performance. This design ensures that S.A. actuators deliver consistent and dependable operation, regardless of load changes.

 

 

 

Conversely, double-action (D.A.) actuators, while offering more robust thrust, tend to increase in size with rising air pressure and required stroke.

However, double-action actuators with a return spring present a balanced solution: the air pressure's full thrust on one side of the piston is effectively countered by a combination of compressed spring and air pressure on the opposite side, achieving efficient operation. This configuration allows for a fail-safe action without the need for complex or unreliable pneumatic systems, and the net air pressure thrust is only marginally reduced by the spring, ensuring optimal performance.

DESIGN DETAILS

PRESSURE/TEMPERATURE RATING
Our cutting-edge Compact Pneumatic Piston Actuator is designed to withstand up to 8 bar, which marks the rated supply pressure and also defines the integrity threshold for the sliding seals of the piston. Every actuator undergoes a rigorous hydrostatic test at an impressive 10.5 bar prior to leaving our facility. The temperature limits for continuous service at 8 bar are meticulously detailed in our comprehensive material table.

ACTUATOR BODY
Crafted from a precision steel tube, the cylinder ensures impeccable performance.
The interior is exquisitely lapped, chromium-plated, and polished to perfection.
The robust heads are available in either aluminum or steel cast and come in diverse configurations to seamlessly integrate with various valve assemblies or operations.

Options include a fork on the top or bottom head designed for pivoting assemblies, ideal for actuating butterfly valves.
Additionally, a flange option is available, engineered for firm assembly on valve yokes, perfectly suited for actuating globe or angle valves.

PISTON
High-strength steel pistons are equipped with either one (S.A.) or two (D.A.) resilient rubber sealing rings, complemented by two (S.A.) or one (D.A.) loaded-teflon guiding skid, ensuring smooth and reliable operation.

STEM
The stem is precision-engineered from stainless steel, meticulously ground, rolled, and threaded on the exposed end. It connects seamlessly to the valve stem via a dual-piece, expertly bored and threaded block, securely fastening the stems together.
Guided by a dual bronze bushing in the lower head, the stem features an integrated felt ring for wiping, along with a sealing ring (excluding S.A. direct-acting actuators), preventing leakage with utmost efficiency.
