About Pneumatic Diaphragm

 
The innovative 1-X280 series straight-stroke pneumatic diaphragm actuator is engineered with a cutting-edge multi-spring architecture. This remarkable design encompasses two dynamic forms: positive and negative action, allowing for seamless customization of the valve's fault position via the spring reset. Perfectly paired with the straight-stroke valve, it excels in the precise control and fine-tuning of process parameters, boasting an impressive maximum stroke of 76mm. As a high-performance pneumatic actuator, it dazzles with its lightweight construction, powerful thrust, and straightforward design, ensuring exceptional functionality.
Meet the 1-X250 series straight-stroke pneumatic diaphragm actuator, designed with a single-spring structure for enhanced functionality. Distinguished from the 1-X280 series, the 1-X250 series is tailored for long-stroke control, offering an extraordinary maximum stroke of 250mm. Compared to pneumatic piston actuators, it stands out with superior adjustment accuracy and a lightweight profile, making it ideal for cutting applications. Equipped with state-of-the-art components like a pneumatic valve, speed increaser, and fast discharge valve, it guarantees rapid cutting, achieving minimum fast cutting times as swift as 1S.

High-Quality Multi-Spring Pneumatic Diaphragm Actuators with Painted Finish
Engineered for an impressively long service life, our actuators set the standard for durability and performance.
Each membrane cover is meticulously crafted from stamped steel, boasting a galvanized and painted finish. This dual-layer of protection not only wards off corrosion but ensures the paint remains resilient and intact over time.
Constructed from either cast steel or forged steel, the actuator bracket offers unmatched firmness and reliability, standing as a testament to superior engineering.
Our diaphragms, made from high-quality neoprene, excel in resisting aging, chemical exposure, and deformation, even under constant stress, ensuring longevity and reliability.
The push rod boasts an AISI420 composition, with a nickel-plated, extruded surface that gleams with high finish, offering top-tier corrosion resistance.
Crafted from aluminum bronze, the guide bushing ensures precise guidance with minimal deformation, even at low temperatures, guaranteeing a perfect seal for the air chamber.
The connection at the actuator bracket is expertly sealed with an 'A' type sealing ring, effectively preventing any intrusion of oil, sand, or dirt, ensuring uninterrupted operation.

Unparalleled Application Flexibility
The design allows for full interchangeability of all positive and reaction components, simplifying maintenance and upgrades.
With adjustable spring installation positions to match your unique stroke requirements, the integrally cast aluminum tray offers both high and low installation points. Choose from 3, 4, or 6 springs to tailor the spring range to your specific needs.
Experience customized performance with varying spring ranges for each actuator, accommodating a diverse array of valve diameters.
Select from two versatile handwheel mechanism styles: top-mounted or side-mounted. The side-mounted option provides complete detachment from the actuator for easy installation.
Seamlessly integrate the actuator and valve using the innovative pressing plate and sleeve structure, making on-site packing replacements a breeze.
Effortless installation elevates overall user experience, ensuring quick adjustments and maintenance.
This robust structure ensures a stable and reliable connection, enhancing the performance and longevity of both actuator and valve.
Choose from a suite of Options designed to perfect your actuator experience:
Precision Adjustable Options

The adjustable upper travel limit precisely controls the upward movement of the actuator, ensuring optimal performance.
Similarly, the adjustable lower travel limit offers fine-tuned control over downward movement, enhancing functionality.
Top-mounted handwheel mechanism for manual control.
Side-mounted handwheel mechanism for ease of access.
Specialized Actuators for Varied Temperatures
Low-temperature actuators are expertly designed to operate efficiently between -60 to 70 ºC.
With robust design, ensure performance in extreme low temperatures.
High-temperature actuators deliver reliable performance from -20 to 100 ºC, ideal for hotter environments.
Our actuator locking device guarantees that your system remains securely locked during maintenance, mimicking the actuator's fault position for added safety.
Further enhance your actuator system with accessories like position transmitters, manual mechanisms, and maximum/minimum adjustable mechanical limits.
Expand control capabilities with additional accessories such as positioners, pressure reducing valves, solenoid valves, limit switches, lock valves, boosters, amplifiers, and pneumatic valves, facilitating a comprehensive control circuit.
