• The Actuator will be electrical quarter turn (or) pneumatic spring return type (or) 3 Position Mechanical Stopper Pneumatic Actuator.
• The operation sequences fixed from full open, partial open to full close.
• Infinite intermediate positions are possible with the limit switch.
• It can be fine tuned to the application easily.
• The settings can be changed at site with ease, by simply adjusting the third cam provided for limit switch.

Tamper proof manual valves are manual valves fitted with supervisory / limit switches to provide the position of the valve to the control system / logic.These valves are used in critical fire water circulation systems, where the manual valve has to be kept open continuously. The limit switches (SPDT) mounted on top of the manual valve gets in contact with the valve shaft / handle or hand wheel gear box and provide NO / NC feedback to the control system stating the position of the valve.
If anyone tampers the position of the valve, the same provided as the feedback to the control system that the valve is in open / close position.
The typical usage of the tamper proof manual valves is in a fire water circulation system in Building management system (BMS).

Limit Switch / Tamper Proof Switch Types:

• 1 NO + 1 NC SPDT Switches
• 2 NO + 2 NC DPDT Switches
• Proximity Sensors ( NO / NC)

Application: Fire Water Circulation Systems in BMS and Critical application where the valve to be in either open / close position unaltered during operation.

Automated valves can be customized for special application with respect to customer logic circuits and system requirements. Any type of valves, gates and dampers

Actuator Types:

• Pneumatic Rotary & Linear
• Electrical Rotary & Linear

Application: Any application as per customer system requirements.

Example: Batching Control System, Inching Application, Remote Control Valves, Wireless Switching Valves, Scada Control Valves, etc..

Retrofitting valves with new actuators and/or manual valves to automate them presents numerous advantages:

• Recalibrating muscle/actuation to ensure actuator operation, in line with changing valve torques
• Additional diagnostics to monitor the health of the valve
• Reduced operational / maintenance costs
• Increased safety and visibility on the health of the actuator
