●Product Features of Pneumatic Centerline Butterfly Valve

1. The pneumatic actuator uses an extruded high-strength aluminum cylinder body, with a finely ground and polished inner surface and hard anodizing treatment, resulting in a low friction coefficient, long service life, and strong corrosion resistance; double-piston rack and pinion design, compact structure, symmetrical installation position, convenient change of output shaft direction, long service life, and quick action; high-precision gears and racks, with small meshing clearance and high precision, providing high output power; fully compliant with the latest international standards: output shaft slots and screw holes; top mounting hole dimensions comply with NAMUR standards; air source interface dimensions comply with NAMUR standards; bottom mounting hole dimensions comply with ISO5211 and DIN3337 standards, facilitating the installation of accessories such as solenoid valves and limit switches.

2. Installation of a double-acting pneumatic actuator and a two-position five-way solenoid directional valve can control the opening and closing of the valve; installation of a single-acting pneumatic actuator and a two-position three-way solenoid directional valve not only controls the opening and closing of the valve but also ensures that in the event of an air source failure, the valve automatically stops at a preset safe position, either open or closed.
