Actuator

Economic advantage

Use of monobloc casting of piston-rack assembly results in reduced housing 

by 10% to 15%, and saves air consumption for valve actuation

Extended service life with monobloc casting of two pistons and a gear-rack

Threads of a gear-rack is positioned in the center of actuator housing, and two 

pistons are cast in intergration with gear-rack as one-piece unit. This helps to keep piston position in parallel during actuator travel. 

Light and compact housing 

Employment of diecast aluminum for housings and piston-rack assemblies has reduced the actuator weight by 20% to 40% for better torque-to-weight ratio

Conformity to international standards 

NAMUR VDI/VDE 3845 designs are used for tubeless mounting of solenoid valve and switchbox on actuator housing besides the conformity to ISO 5211 requirements for valve mounting flanges. The stem top design also conforms to NAMUR dimensions.

Optional adptors to the valves on the bottom of actuators can be provided for wide mountong variations
