Pneumatically Actuated Valves

Electropneumatic-Pneumatic-Positioner.png

Electropneumatic Pneumatic Positioner
Valve positioning is achieved by Electropneumatic / Pneumatic positioner

Limit-Switch

Limit Switch
Limit switch helps in confirming the position of the valve by showing visually as well as through feedback from micro / proximity switches.

Soleniod-Valve

Soleniod Valve
Solenoid valave helps to regulate the direction of flow of air into the actutaor. Namur solenoid valves directly fit the actutaor. Non Namur design valves can be fitted with SS tubing. Design ensures that 5/2 solenoid valves can be converted to 3/2 at site if needed.

Electrically Actuated valves

Electrically-Actuated-valves

Single Phase Electrical Actuator

These actuators are compact, lightweight and direct mount part turn-actuators. These actuators prove to be cost effective solution for automation of small valves & dampers. They are useful in Ball valve, Butterfly valve, Plug valve, Multi louver damper, Butterfly damper, Inlet Guide Vane
Three Phase Electrical Actuator

These actuators offer cutting edge actuation technology for the automation of final control elements, used extensively in process industries like power, steel, cement, chemical & petrochemical, pharmaceutical, paper, food & beverages, water treatment etc
These actuators are rugged, robust and designed to automate a variety of multi turn loads when mounted directly and for part turn loads when coupled with reduction gerabox.
Linear Single Phase Electrical Actuators

These units are most suitable for control / regulating duty application of various types of valves such as Globe, V-notch ball, butterfly, diaphragm and single ? multi louver dampers.
The actuators are supplied with various types of accessories & can directly work on the control signal of 4-20 mA & also give feed back signal 4-20 mA with respect to actual mechanical position of the final control
