Actuator Features

Service Life

1. The diaphragm cover is made of premium stamped steel, with a cutting-edge galvanized and painted finish that fuses durability with corrosion resistance. This resilient coating remains robust and unyielding over time. The actuator's bracket, crafted from either cast or forged steel, guarantees unmatched structural integrity and reliability.

2. The diaphragm is constructed from high-quality neoprene rubber, delivering superior resilience against aging and chemical exposures, while maintaining its integrity and form under continuous operational pressure.

3. The push rod is made of AISI420, boasting a nickel-plated surface that exudes exceptional smoothness and formidable resistance against corrosion.

4. The guide bushing is made from high-grade aluminum bronze, providing exceptional guidance and minimal deformation even at low temperatures, ensuring optimal sealing of the air chamber.

5. For the sealing, an innovative A-type sealing ring is employed below the connection of the push rod and bracket, effectively defending against penetration by oil, sand, or dirt.

Application Flexibility

1. All direct-acting and reverse-acting parts are universally crafted to ensure seamless interchangeability, enhancing operational convenience.

2. The adaptable spring installation position can be fine-tuned according to the stroke. The integrally cast aluminum tray boasts dual installation positions - high and low - simplifying the installation process. Moreover, 3, 4, or 6 springs can be strategically configured to offer varied spring ranges, tailored to meet specific operational needs.

3. Each actuator specification is accompanied by diverse spring options, supporting a vast array of valve sizes, thereby enhancing its versatile application.

4. There exist two distinct handwheel mechanism options: top-mounted and side-mounted. The side-mounted handwheel, in particular, offers the convenience of being completely detachable from the actuator, streamlining the installation process.

5. The connection between the actuator and valve employs a sophisticated compression plate and sleeve structure, facilitating effortless installation and on-site packing replacement.
