S pneumatic actuator
Product performance:
Stainless steel actuator with electrolytic polishing on the surface, smooth and beautiful, strong corrosion resistance, suitable for engineering environments with extremely high corrosion resistance requirements.
The double piston toothed gear rack design has a compact structure, symmetrical installation position, convenient change of output shaft rotation, long service life, and fast action.
The back of the piston rack is equipped with composite bearings and guide rings, which have accurate movement, low friction coefficient, and extended service life.
Combined pre loaded coated spring with long service life and strong corrosion resistance.
High precision gears and racks, with small meshing clearance, high accuracy, and high output power.
Stainless steel fasteners, safe and aesthetically pleasing, with strong corrosion resistance.
Adopting international standard dimensions: output shaft groove, screw hole; The size of the top mounting hole complies with NAMUR standards; The size of the air source interface meets the NAMUR standard

SIMMEL Three position actuator provide an operation of 0°, 45°, 90°or 0°, 90°, 180°, The midway position is achieved by a mechanical stop of movement on the 2 auxiliary pistons. This midway stop positions adjustable. Example:
90°actuator can provide 20°, 30°, 40°, 50°, 70°etc.

Valve air unit essential to provide clean and dry supply air to valve positioners, solenoid valves and pneumatic actuators.
Simmel's Type 50 & Type 100 Filter Regulators are reliable precision units designed for instrumentation and general purpose use in both standard environments (Type 50), and corrosive environments (Type 100).

The SIMMEL 512 series declutch override gear box were specially designed used for butterfly valve, ball valve and plug valve together with pneumatic actuators.
This device allows for manual operation during installation, system testing and in the event of supply air-failure.
The SIMMEL 512 Series mount directly to many of the most popular rack and pinion style actuators on the market, and does not require a bracket between the pneumatic actuator and declutch override.
The units come complete with a coupler that connect the pneumatic actuator to the valve.

The Simmel pneumatic valve clutch is applied in the installation, debugging, and manual operation of pneumatic ball valves, butterfly valves, and plug valves when the system loses air or power.
Designed according to the ISO5211 standard, with a reasonable structure and reliable performance, it is an indispensable working component in the pneumatic valve control system.
