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 12V DC 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 13 mm, the Kv-value is 10 (166.7 l/min at dP=1 bar). The time for opening or closing is approximately 6 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 On/Off control. This means that two wires are permanently connected to the power supply. Powering the control wire opens the valve electrically, disconnecting the control wire will close the valve electrically. 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.
  • 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.
