Electrical Ball Valve BW3 3/4'' 3-way 24V AC 3-point
3 way electrical ball valve with 3/4 inch female threads (BSP) and energy efficient 24V AC actuator. Suitable for liquids and gases (max 110°C) and a pressure from 0-10 bar. Suitable as zone valve in heating systems. The valve has a brass housing with chromed ball and PTFE valve seats. The nominal diameter is 12.5 mm, the Kv value is 8.6 m3/h (143.3 l/min at dP=1 bar, water). 3-wire connection (3-point): neutral wire and 2 control wires (to open/close). The valve opens in 16s.

Description
Very energy efficient and robust 3 way JP Fluid Control electric ball valve to open or close pipes electrically. The valve has 3/4 inch threads (female thread BSPP) and a 24V AC actuator (IP54). This valve is suitable for liquids and gases (-10 to 110°C) and is often used in heating systems. A ball valve is less sensitive to dirt than a solenoid valve. It is however recommended to install a filter before the valve. The valve body is made of brass, the ball is chrome plated and the seal is PTFE (Teflon). The orifice is 12.5 mm, the Kv-value is 8.6 (143.3 l/min at dP=1 bar). The time for opening or closing is approximately 16 seconds. This 3/2-way ball valve is best used to change flow direction from one output to the other, not stop the flow.
Installation
The actuator has a 3-wire connection, and must be connected as shown in the diagram below. The actuator is supplied with a cable. The actuator has 3-point control. One wire is permanently connected to the neutral. The other two wires are control wires to rotate the ball in both directions (connect to the phase). Please note: never connect the two control wires at the same time, this could damage the actuator! The actuators can be supplied with an integrated relay (On-Off control), in that case only one control wire is needed. The actuator includes limit switches, energy is only consumed during opening or closing of the valve.
The 3-way valves can be connected in two different ways as shown in the schematic below.
Important
- Please observe the color coding of the wires. Never connect the two control wires at the same time, the actuator will be damaged.
- Suitable for clean gases and liquids, including cold & hot water.
- Make sure that the valve is suitable for the application and that the materials are suitable for the medium and the temperature.
Note: this valve is not suited for dry gases such as unlubricated compressed air.
