Actuation Capacitor Return Low voltage
The BAP series electrically actuated ball valves automatically returns the valve to its original position when de-energised. The compact design works in the same way as a solenoid valve and can be considered ‘fail safe’ once the storage capacitor has charged up (approx 30 seconds). Unlike a solenoid valve the BAP can take full pressure in either direction, eliminating the need for a check valve. The BAP series has a wide range of industry applications namely; dirty or contaminated fluids, viscous fluids, some corrosive fluids (check compatibility), gravity feed applications, anti water hammer slow close function, IP67 corrosive resistant enclosure, low power/solar/battery operated circuits (9-24v AC/DC). Threads conform to ISO 7.1 Sealing Threads.

What is an Auto Return Electric PVC Ball Valve?
An auto return electric PVC ball valve is constructed of PVC with a direct mounted IP67 capacitor return electric actuator fixed to the valve which conducts its 90 degree turn (open & close). They have teflon (PTFE) seats with FKM seals. The valve is what we call a two wire operation (for instance similar to a solenoid valve) where as long as power has been continuously supplied to the unit for 30 seconds it will close by drawing from the capacitor when the power is removed from the unit (power turned off or power failure). This gives the advantage of a solenoid valve without the disadvantages in situations where the media is dirty and would clog a solenoid valve (although its cycle time is slower).

How does a Capacitor Return PVC Ball Valve work?
The ball valve itself works 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 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 a capacitor return electric actuator which is connected to a shaft which in turn is mated to the ball by a female slot. The electric actuator needs 30 seconds to charge before the capacitor has enough capacity to close the valve when power is removed. There are only two wires going to the actuator so it effectively has two states; on or off. The unit has a manual override on the top of the actuator to manual operate the valve.

How long will my Electrically Actuated Auto Return 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.

How do I install a Capacitor Return PVC Ball Valve?
Before installation the line must be isolated and pressure removed. The valve itself has female parallel BSP threaded ends so it is best to put a male tapered BSP fitting into the valve ends. Thread tape or a sealant should be used to help the seal and also if dissimilar metals are used it will reduce dissimilar metal corrosion. The electric actuator has only two wires leading to it so effectively only has two states which are on or off.

What are typical uses of an Auto Return PVC Ball Valve?
These are really used in applications where a solenoid valve would be used but the media does not allow this such as where there are too many suspended solids and would clog the bleed holes in a solenoid valve. The two wire application allows a normally closed or normally open function (capacitor return to that position) although it can not be considered fail safe as if it has not had enough charge time (roughly 30 seconds) it will not fully return. Being PVC they are quite often used on corrosive media or environments such as salt water.

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.
