Remote Battery Powered Actuators

Actuators for Buried Valves

The 3S Series of battery powered actuated valves are an excellent solution for remote operation of valves in underground infrastructure networks. Using cellular communications, the 300D model (45 ft/lbs and 90 ft/lbs) is ideal for small diameter butterfly, ball and gate valves due to the compact size and minimal installation depth.  The 500D model (peak torque of 400 ft/lbs) is the ideal multi-turn actuator for geared ball and butterfly valves, gate valves with reduction gear, and gate valves without reduction gear up to DN400.  The actuators are waterproof and can be installed directly into the ground beneath a standard street cap or a manhole cover. Retrofitting of existing buried valves is also economically feasible.
Remote battery powered actuators are ideal for:

• Monitoring and servicing hard to access valves;
• Critical burst mitigation;
• Automated rezoning of system;
• Critical asset operation;
• Remote valve condition and position monitoring;
• Integration into SCADA and GIS platforms.

Critical burst mitigation
Remote battery powered actuators can provide automatic shut-off based on sensor data or by instruction from the control centre, reducing water loss.

Automated draw off/Syphon
Actuators can be placed on draw off/ Syphon points linked to a level sensor ensuring optimized water collection in line with environmental requirements.  ​

Active DMA's
Actuators can be programmed to rezone DMA's or to provide day/night DMA pressures (in conjunction with needle valves) at a specific time each day. 

Flood defence 
Automation of flood mitigation assets (penstocks and tilting weirs) divert water from control centre in response to flooding or flood warnings ​

Automated rezoning
Actuators can be placed in optimum positions to enable automated rezoning in the result of loss of an asset (reservoir or pumping station) or a burst

Hard to access valves 
If a valve is in a location which is difficult to access a remote battery powered actuator can be installed enabling remote operation of the asset.

Aqueduct control 
One 3S actuator can replace a standard 400V actuator, Backup battery supply and associated civil works. Significant cost savings can be realised with this approach

Critical asset operation 
When response time is a key concern automating valves means control is available within minutes rather than waiting for operatives to travel to the asset

Remote sites with 230V power 
Many reservoir and remote sites have 230V power but no 400V power making traditional actuation very costly.  3S actuators can run from a rechargeable battery which can trickle charge from a 230V supply making actuation easy
