Actuator Features

Service Life: Durability and Reliability Redefined

1. The diaphragm cover, a marvelin design, is meticulously crafted fromstamped steel, featuring a galvanized and beautifully paintedsurface that excels in resisting corrosion. The paint is formulated for outstanding durability, ensuring it remains intact. The actuator bracket, constructed from cast or forged steel, offers an exceptionally robust and reliable structure.

2. The diaphragm is ingeniouslycrafted using high-grade neoprene rubber, embodying unparalleled resistance to aging and chemical corrosion, whilemaintaining structural integrity even under continuous stress.

3. The pushrod, a pillar ofstrength, is engineeredfrom AISI420, embellished with a nickel-plated surface that providessuperior smoothness and ultimate corrosion resistance.

4. The guide bushing, a hallmarkof precision, is expertly made from aluminum bronze, ensuringexceptional guidance with minimal deformation at low temperatures, thus maintainingoptimal air chamber sealing.

5. For sealing prowess, an A-typesealing ring is astutely placed belowthe connection point ofthe push rod and bracket, ingeniously preventing oil, sand, or dirt intrusion.

Application Flexibility: Adaptability at Its Best

1. Universality is key as all direct-acting and reverse-acting components are crafted forseamless interchangeability.

2. The spring installation is adjustable to fit any stroke, with an integrally cast aluminum tray offering dual installation positions: high and low, ensuring utmost installation convenience. Meanwhile, choose from 3, 4, or 6 spring configurations to tailor the spring range to your exact needs.

3. Every actuator specification is paired with multiple spring options, accommodating a vast array of valve sizes for unparalleled versatility.

4. Handwheel mechanisms are offered in two innovative types: top-mounted and side-mounted. The side-mounted handwheel can be entirely detached, revolutionizing installation ease.

5. The actuator-to-valve connection uses a clever compression plate and sleeve structure, streamlining installation and facilitating effortless on-site packing replacement.
