with capacitor return will auto return close upon electrical power failure (Option failsafe Open or 1 wire control or UPVC ball valve). This particular ABV model comes with IP67 protection with a strong ABS housing with duty cycle exceeding 70,000 open/close cycles, E2 fully open and fully closed volt free position feed back switches, manual over ride and is supplied with either 11/4", 11/2 or 2" BSP or NPT threaded stainless steel full flow ball valve with WRAS PTFE seals offering a pressure range 0 to 10 bar and a maximum media temperature of +100ºC. This ABV actuator utilizes a slightly more powerful 22 watt electric motor offering a torque output of 20 Nm to cope with these larger ball valves and requires only 10 seconds to fully open or 10 seconds fully close. Available voltages include 12v-24vDC, 24vAC or 110-240 AC/DC 50/60Hz. Each actuator will work within each specified voltage range chosen which is especially helpful if running from 12 or 24 volt such as a camper van, boat, motor-home power supply which can vary according to battery charge status. Any 110-240 volt actuator will work from any applied AC voltage from 110 volts through to 240 volts 50/60Hz. This particular model is supplied complete with visual position indicator and E2 position feed back switches.

Most electrically actuated or motorised ball valves in the market today are larger heavy cumbersome power to open, power to close with no power no valve movement. In some applications it is helpful to have a fail safe position closed auto return electric actuated ball valve so that when electrical power is removed or power supply fails the actuator will automatically return back to its original position i.e. failsafe close, which offers a much higher level of safety, energy saving and simplified valve set-up, installation and control.
Typically this has been achieved with either an additional costly, heavy, large rechargeable industrial battery back up or has been achieved with a strong internal spring return mechanism requiring a heavier duty more powerful electric motor but both these offer disadvantages in either terms of cost, size, wiring and or reliability.
A normally closed motorized ball valve is also known as a N/C ball valve, spring return closed actuated ball valve, failsafe position closed valve.
A normally open motorised ball valve is also known as a N/O ball valve, spring return open electrically actuated valve, failsafe position open valve.
The ABVM miniature 5 watt series electrically actuated ball valve standard series with the new auto return electric actuator offers a compact, guaranteed fail-safe valve actuator return from an integral power backup supply, simple 2 wire control power open fail safe close, patented floating valve seal design, low power consumption can br controlled by either any 9-24AC/DC signal or 110 to 240 volt AC 50/60Hz power supply. The ABVM (Actuated Ball Valve Miniature) are mounted to a full flow (full bore) 304 stainless steel ball valve with PTFE seals with a pressure rating from vacuum to 10 Bar and a maximum media temperature of +100ºC. The combination makes this an attractive, low cost, compact solution for many fluid and gas applications such as HVAC systems, waste water treatment, chemical processing and dosing, motor home waste water, caravan water systems, boat hot - cold - waste water, diesel fuel line safety control, vegetable oil systems, rainwater recovery, underfloor and central heating systems, building management systems, retirement home water control, prison water isolation systems and just about any thick liquid or corrosive gas contaminated, particles debris which are suited to 304 stainless and PTFE.
With technical advances and reliability in reduced electric motor power consumption and electrical components it is now possible to offer a two wire electrically actuated miniature ball valve with integral capacitor energy storage that will offer fail-safe operation for over 70000 cycles that consumes less than 5 watts when moving, under 1 watt after reaching full position in powered state.
The miniature ABVM WRAS approved compact actuated ball valve on the left offers quick 3 to 5 second actuation time with 2 Nm torque optional 3/8", 1/2", 3/4" and 1" full flow stainless steel 10 bar rated ball valve with IP67 ingress protection, media up to +100ºC available control voltages 9 to 24vAC/DC (any 9 to 24 volt AC or DC supply) or 110 to 240 volt AC 50/60Hz (i.e. any 110vAc through to 240v AC supply).
When power is applied this ABVM-AR (Auto Return) normally closed compact actuator will quickly actuate the ball valve into the open position (3 to 5 seconds) and will quickly recharging the internal capacitor (typically maximum 6 to 10 seconds required after each use). When in the fully open position and recharged the actuator stops taking power and the valve stays in the open position. When electrical power is removed the actuator detects the power loss and draws power from the internal capacitor (electrical storage) which enables the ball valve to automatically return to the closed position without the need for any additional signal or electrical power. The capacitor is quickly recharged during the next power open cycle and will draw any additional charge if required until power is removed.
An initial 10 to 15 second (New Out of the Box) charge is only required when initially installed to fully charge the capacitor, there after only requiring a 6 to 10 seconds recharging period.

One of the major benefits of this type of actuated ball valve is not only the full uninhibited flow normally associated with a solenoid valves in, up, over, down and round flow path but also benefits from being unaffected by debris, back flow typically found in rainwater systems but also requires a much lower power demand size for size and greatly reduced heat build up making this design of control valve ideally suited for hard water, BMS building and Zone valves, gravity fed waste water systems from motor caravans, motor homes, boats, yachts but also diesel, biogas and petrol fuel lines, compressed air, mains water, RO water and most other even thick liquids and corrosive gases that are suited to stainless steel and PTFE.

Auto return actuated ball valve 11/4", 11/2" or 2" BSP type ABV-AR.
The ABV standard WRAS approved motorised ISO5211 ball valve with fail-safe close also known as normally closed actuated ball valve Working on the same self closing or fail-safe actuator circuit the actuator will detect electrical power loss and then will draw energy from the internal capacitor to automatically power the motor to move the ball valve. An initial charge of 60 seconds is required when first installed which happens during the first power open sequence and from this point forward the valve will always maintain its own back up power supply.
ABV-AR auto return actuator (Normally closed or normally open) and 3 wire control ABV quarter turn actuator (Power Open - Power close) can be mounted to UPVC 2 way 3 pc 10 Bar +100C rated ball valve (EPDM sealing option FPM sealing), for port sizes 1/2 to 2" thread or weld / cement end. These are ideal for very aggressive fluids and gases and especially sea water and swimming pool water applications. The ABVP PVC actuated ball valve is supplied complete with visual position indicator, and is 100% duty rated to 50,000 open/close cycles has a low power 22 watt low power fast acting 15 motor and typically supplied with volt free open and closed position feed back switches. |
