The outer surface of the actuator is specially designed and has a smooth surface (special design on demand) for typical pharma application - hence cleaning becomes very simple.


• Ball valves / Butterfly valves of required sizes & materials and can be coupled with pneumatic actuator (single acting, spring return or   double acting) and solenoid valves.
• Dom type position indicator for on-off indication can also be provided with above assembly.
• Above valves can also be provided with Pneumatic / Electro-Pneumatic Positioned with input supply of 3-15 PSI/ electrical signal of 4 to   20 mamps for percentage opening of the valves.

Technical Specifications:
• Double acting / single acting spring return actuators
• Degree of rotation: 90 Deg (Up to 360 deg on request)
• Rack & pinion mechanism
• High torque & durability.
