Features:
Optimum corrosion resistance is achieved with anodized housing, zinc plated/chromated pinion, powder coated end caps, chromated pistons and stainless steel fasteners.
Equipped with O-ring seals, low-friction piston and pinion bearing materials and grease for a low maintenance and trouble-free cycle life.
Dual travel stops allow for fine adjustment of the open and closed positions.
The nominal rotation (90 degrees) has an adjustable range of +5 and -5 degrees at each end of travel.
Optional end cap stroke limiter available.
Springs are specially designed for a long cycle life.
Spring cartridges allow safe and quick conversion of spring sets to match your torque and pressure requirements.
Double rack and pinion design nullifies side loads on the pinion shaft, minimizing bearing wear and extending life.
Bearings are designed for lower bearing forces and a longer cycle life.
Complies with the latest European directives like ATEX (2014/34/EU), and PED (2014/68/EU) for use in a wide range of industrial applications.
Flexible and cost effective valve mounting is achieved by fitting the valve flange with 2x ISO drilling patterns and fits the pinion with a Star Drive for both ISO5211 and DIN3337 installations.
Standard NAMUR (VDI/VDE3845) equipment can be mounted to the solenoid and top accessory flanges.
