Feature
option to change spring range w/o extra parts
-diaphragm actuator mounted on the columns
- wide range of the available forces
- linear relationship between rod displacement and control pressure as a result of using membranes with constant active area
- various ranges of spring pressures due to changeability of spring number and /or dislocation of distance fencers
- capability of the diaphragm actuator to incorporate side-mounted handwheel, pneumatic or electro-pneumatic positioners, limit switches, air sets, three-way pneumatic solenoid valves, lockup valves, position transducers,
-possibility to equip with accessories allowing to decrease or increase distortion time
- high strength of diaphragms, springs and packings
- small size and weight
