●ISO5211 Flange Standard: This standard adopts a combination of ISO5211 international standard and industry standard for flange dimensions, allowing for direct installation on the top of various valves.
●Namur Standard Connection: The accessory connection dimensions are designed according to the Namur standard and can be directly connected to control accessories such as solenoid valves and limit switches.
●Diverse Drive Shaft Kits: The introduction of detachable drive shaft kit technology enables direct adaptation to various types of valve drive rods.
●Low friction coefficient and long service life: The design with oil-filled bearings and polyethylene bearing guidance reduces the friction coefficient and ensures smooth operation and extended lifespan.
●Reversible gas loss opening and closing adjustment: With a symmetrical design, users can quickly and conveniently switch between gas loss closing and gas loss opening at the site.
●Torque Range: The spring return torque range is between 17 and 1850 Nm, and the maximum pneumatic torque can reach 3500 Nm.
●Working Pressure: The working pressure can be selected within the range of 1.0 bar to 6.2 bar (15 - 90 PSI).
●Working Medium: The working medium is gas, water, and mineral-based hydraulic fluids.
●Travel Adjustment: Equipped with a bidirectional adjustable limit device, it can be adjusted within < ±5° at the fully open or fully closed position.
●Mechanical Locking: In the event of spring failure, the actuator can be mechanically locked to ensure safety.
●Corrosion Resistance: The exterior is coated with UV-resistant polyester, all fasteners are made of stainless steel, and a polytetrafluoroethylene coating is optional to enhance corrosion resistance.
●Lubricant-free Maintenance: Lubrication treatment has been done before leaving the factory. The mechanical rotating parts use oil-filled bearings, and no further lubrication is required during use.
