• What is a Way Electric PVC Ball Valve?

  A two way electric UPVC ball valve is constructed of UV Stabalised PVC (known commonly as UPVC). It has an IP67 electric actuator fixed to the valve by the way of an aluminium bracket and drive dog which conducts its 90 degree turn (open/close). This kind of ball valve design makes it easy to remove from the line as you do not need to unscrew its ends from the pipework to maintain the valve. It is also very easy to change the valve seats as you can access them directly when the ends are removed making them ideal for applications where the seat is worn regularly. They have teflon (PTFE) seats and the choice of either EPDM or FKM seals (choose depending upon your usage case). The end pieces have a choice of either threaded or solvent weld and can be interchanged very easily. The actuator comes with extra limit switches for voltage free end of stroke open/close feedback and a visual indicator.

• How does a PVC Electric Valve work?

  These UPVC electrically actuated ball valves work the same as any normal two way ball valve whereby the ball is rotated 90 degrees within the body of the valve which will either open or close the valve. The ball itself has a hole at either end which the media will flow through when it is open. When the valve is closed these holes are blocked off to the flow effectively isolating the media either side of the valve. The ball is turned by an electric actuator which is connected to a shaft which in turn is mated to the ball by a female slot. When the actuator is operated by an external relay it will take anywhere from 8 to 20 seconds for a cycle depending upon the actuator size (it generally gets longer as the actuator size increases with required torque). Once it rotates its required 90 degrees a microswitch on a cam is triggered and power to the motor is shut off. It will then wait for the relay to be switched and the valve will do the same thing in the other direction.

• How long will my Two Way Electrically Actuated PVC Ball Valve last?

  Like any valve this depends upon the usage case of your ball valve, its environment, media and how many times it is cycled. For instance if it is on a clean media, in a clean environment and not cycled regularly the life will be decades or more. If it is on a corrosive media and in a dry application with a high cycle rate the life will be much shorter. It is relatively easy to change the seats out when they wear which is the main perishable in the valve. These are available as spare parts in a repair kit. The actuator's life will depend upon how clean the environment is, its correct installation, its duty cycle and electrical supply. Being CE certified they have been tested to 6,000 life cycles for general purpose applications but can last much longer. One common mistake we see is an incorrectly rated cable gland being installed. Our actuators are IP67 which gives you great water ingress protection but it will only be as good as the cable gland installation. You need to bear in mind the duty cycle of the actuator model you are using and do not exceed that eg. (if it is 75% you can use the actuator for 75 seconds with a 25 second down time out of 100 seconds). If you do it can lead to premature failure of the actuator.

• How do I install a PVC Electric Ball Valve?

  As this is a 2 way valve it will need to be fitted between either two threaded or two solvent weld connections (the valve has two female ends). The electric actuator must be wired in accordance with the wiring diagram which is on the front of the actuator and also inside the housing. This varies between models and voltages so if there is any doubt please consult us.

• What are typical uses of a PVC Electrically Actuated Ball Valve?

  These electrically actuated PVC ball valves are mainly used in water treatment or chemical dosing applications due to their chemical resistance. They however can really be used in any application where the medi, temperature and pressure are compatible with the valve.

• How long will my product take to get to me? 

  This depends upon where you are based and the freight method chosen. If the express freight option is selected it is usually next day delivery to metropolitan areas in Australia for under 5kg. If free freight has been selected it will go by road freight which can be anywhere from 1 to 10 days depending upon your location. It usually averages 3 days.

• What warranty do I get?

  All of our products come standard with a 12 month warranty. The good news is we have very strict quality controls and all valves leave our warehouse tested (full material and testing certificates to API598 are available) and inspected so there are rarely any issues. Also once your valve is in and operating it will most likely continue to do so for a very long time.
