The 1-X250 series linear stroke pneumatic diaphragm actuator is an engineering marvel that utilizes a sophisticated single-spring structure. This innovative design primarily caters to long-stroke applications, boasting an impressive maximum stroke capacity of up to 250mm. When juxtaposed with the 1-X280 series, the 1-X250 series excels in delivering enhanced control for extended strokes, making it an ideal choice for demanding operational settings. In comparison with traditional pneumatic piston actuators, this model stands out with its exceptional regulation precision and remarkably lightweight profile. Such attributes make it a superior alternative, providing not only high-performance control but also ease of use.Furthermore, it is adeptly designed to be utilized in cut-off applications. When paired with pneumatic control valves, boosters, and quick exhaust valves, it achieves unprecedented cut-off times as short as a mere 1 second, marking its excellence in rapid response scenarios.

Service Life
1. The diaphragm cover is made of stamped steel with a galvanized and painted surface for corrosion resistance. The paint is designed to be durable and not easily peel off. The actuator bracket is made from cast or forged steel, ensuring a robust and reliable structure.
2. The diaphragm is constructed from neoprene rubber, offering excellent resistance to aging, chemical corrosion, and maintaining its shape under continuous stress.
3. The push rod is made of AISI420 with a nickel-plated surface, providing high smoothness and corrosion resistance.
4. The guide bushing is made from aluminum bronze, ensuring good guidance and minimal deformation at low temperatures, which maintains good air chamber sealing.
5. For the sealing, an A-type sealing ring is used below the connection point of the push rod and bracket to prevent oil, sand, or dirt from penetrating.
Application Flexibility
1. All direct-acting and reverse-acting parts are universal to ensure interchangeability.
2. The spring installation position can be adjusted according to the stroke. The integrally cast aluminum tray offers two installation positions: high and low, making installation convenient. Meanwhile, 3, 4, or 6 springs can be configured to achieve different spring ranges.
3. Each specification of the actuator comes with various spring options, accommodating a wide range of valve sizes.
4. There are two types of handwheel mechanisms: top-mounted and side-mounted. The side-mounted handwheel, in particular, can be completely detached from the actuator, making installation very convenient.
5. The connection between the actuator and the valve uses a compression plate and sleeve structure, facilitating easy installation and convenient on-site replacement of packing.
