3 way UV stabilised Electric PVC true union ball valve available in both L port and T port configurations. Comes with PTFE (Teflon) seats and our unique double stem seal system (standard in EPDM but also available in Viton). Also features a chem lock insert In the end so the true union can be removed for service work and the ball will not leak when in the closed position. Great PVC ball valve for corrosive or chemical media where traditional material such as brass and stainless steel are not suitable. Commonly used in the aquaculture industry (sea water), chemical dosing, water treatment and pool filtration. Choose between Solvent Weld (ANSI Standard designed to fit Schedule 40 & 80 pipe) and BSP threaded ends (Threads conform to ISO 7.1 Sealing Threads.).
Change the 'L' to 'T' for T port. Change the 'B' to 'S' for Solvent Weld. Change the 'E' to 'V' for FKM.

What is a 3 Way PVC Electric Ball Valve?
A three way UPVC electric ball valve operates on the same principle as a two way electric ball valve but instead of a complete isolation or completely open (2 states, closed or open) it will have one line open and one line closed. It is important to note that during its 90 degree turn from one line to another there is a point where all lines are partially open to each other even though this is for a limited period of time (the time for one cycle is around 12 seconds depending upon the actuator size). The 3 way ball valve itself is made of UV stabalised PVC with a mounted IP67 electric actuator. The size of the actuator will get bigger with the size of the valves as the torque required increases. We match all of our actuators with at least a 30% safety margin in torque.. There is a choice of a L or T port configuration in the ball valve and threaded or solvent weld ends. They all have PTFE (teflon) seats with either EPDM or FKM seals.

How does a 3 Way PVC Electric Ball Valve work?
The 3 way ball valve will work by the electric actuator rotating the ball 90 degrees in the valve. This will be in a clockwise or anticlockwise direction depending upon the actuator involved (ours usually open anti clockwise). The actuator itself is controlled by an external relay that you wire in upon installation (eg. a switch). This will then turn the ball 90 degrees as the actuator is mated to the shaft of the ball valve, switching the ports to the other configuration. It is important to note that if power is lost during its cycle the actuator will remain in that position as it has no power to continue (similar to a double acting pneumatic actuator). The actuator itself has a visual indicator as well as an extra set of limit switches for end of position voltage free feedback. Power to the electric motor is cut once the valve does a 90 degree turn (1 cycle) by a switch which is fixed by a cam to the shaft inside the actuator.

How long will my 3 Way UPVC Electric Ball Valve last?
This depends upon the usage case of your valve, its environment, media, supply air cleanliness 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. If it is on a corrosive media and in a dry application with a high cycle rate the life will be much shorter. 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 3 Way PVC Electric Ball Valve?
Before installation the line should be isolated and pressure removed. The valve can be installed in any orientation so choose the best for ease of access for maintenance. The end connections will depend upon whether you have chosen threaded or solvent weld. The 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 so if in doubt please consult us.

What are typical uses of a Three Way Electric PVC ball valve?
These three way PVC double acting ball valves are used mainly on water treatment or chemical dosing/sampling applications. The common theme though is where either a diversion (switching from one line to another) or isolation of one line to change over to another is used. Being power open/power close they are not typically used on fail safe applications however you can get a spring return electric actuator however these are quite rare in application due to the pricing.

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.
