These installation tips are specially meant for electric ball valves from the BW series of JP Fluid Control. Before starting the installation, please read the safety instructions carefully and verify that the electric ball valve is suitable and safe for the application. Check if the valve specifications on the type label on the actuator match with the application requirements. The image below shows an example of a label with an explanation of the various parameters.
Pipe system
The actuators of the AW series are splash proof, but not resistant to severe weather conditions. It is therefore advisable to install electric ball valves in a dry, sheltered spot.
Make sure that the piping is not under pressure and cooled down before you start.
Check the pipes for dirt and clean the pipes if necessary. Ball valves are less sensitive to dirt than solenoid valves, but it is still advisable to avoid dirt if possible. Dirt may increase the wear of the valve. Optionally you can install a pipe filter on the inlet side of the valve.
Use thread sealant such as Teflon tape or Loxeal for the pipe thread. Avoid entry of the sealant into the valve as this may lead to blockage.
Use the correct fittings between the valve and the pipes. While tightening, only excert force at designated areas on the valve, never exert force on the actuator. Avoid stresses in the piping and fix the pipe securely to the wall or frame to avoid vibrations in the pipes.
Positioning of the electric ball valve
The valve must be securely fastened to the pipes using the right type of fittings. Use a wrench for both the valve and the pipe while tightening. Prevent unnecessary stress in the system.
It is recommended to install the valve with the actuator facing upward with a maximum deviation of 90 degrees (see picture). This reduces the risk of collecting moisture in the actuator.
Set the ball to the correct angular position, for example with a wrench. The 2-way ball valves are closed in their standard position. The 3-way ball valves can be set up in two different ways by rotating the ball 180°. The following diagram shows how the 2-way and 3-way valves can be used.
Make sure that the position of the ball in the valve is properly adjusted, so the actuator fits on the valve. Tighten the nut of the actuator by hand.
Wiring diagram
Check the actuator type and use the correct wiring diagram. Improper connection of the wires or using a wrong voltage can cause permanent damage to the actuator!
The rotational direction of the actuator can not be changed by reversing the polarity of the control wires.
The actuators are equipped with two internal end switches. Therefore, energy is only consumed during opening or closing.
The AW1 actuator (JP Fluid Control) opens and closes electrically. There is no spring in the actuator.
Ensure that drops cannot slip along the cable and enter the actuator.

Solenoid Valves:
The valve is actuated with an electric current through the solenoid (electromagnet).
Switches directly.
From 1/8 inch up to 2 inch.
Normally Closed or Normally Open.
Only for clean media.
Uses energy as long as electrically energized.
(Semi-)direct operated: from 0 bar pressure differential.
Indirect operated: from ±0.5 bar pressure diff.
Only one direction of pressure.
Brass, Stainless Steel or Plastic housing.
EPDM, FKM, NBR of PTFE seals.
Electric Ball Valves:
The flow is controlled with a drilled sphere (ball) which rotates around its axis, perpendicular to
the bore.
The ball rotates with the help of an electric motor.
NC = Normally Closed (most chosen): The valve is closed when the coil is not
electrically
energized.
NO = Normally Open: The valve is open when the coil is not electrically energized.
Indirect operated solenoid valves need a pressure differential over the inlet and outlet port for
proper
operation. If the pressure differential is too low (f.e. a gravity fed system or a closed circuit),
only
(semi-)direct operated solenoid valves can be used. These operate from a zero bar pressure
differential.
The type of medium defines the material choice of the valve body and seals. By selecting 'Other',
you can
choose the material for the valve body and seals.
3-Way Solenoid Valve (orifice <3mm):For small flow rate, such as actuation of a
cylinder,
a
(small) fuel system, a test setup, etc. 3-Weg Electric Ball Valve (bore >8mm):For
larger
flow rates, such as central heating, irrigation, compressed air etc.
Choose the right circuit function. The upper diagram shows the flow when the coil is not powered.
The lower
diagram shows the flow when the coil is powered.
personAwesome job. Other than the error on your web page showing the wrong picture of the product, (which has been corrected.) Your customer service is outstanding and has taken care of my needs quite well. you have gone above and beyond to exceed my expectations. Your shipping methods were speedy and your products are very nice. I recommend you to all my friends. Thank You.

personWe just found Tameson online, a good source for solenoid valves. Website very easy to navigate, found what I needed in minutes. Parts arrived 2 or 3 days after ordered online. We will definitely do business with Tameson again.
