This strong and energy efficient 2-way electrical ball valve from JP Fluid Control can be used to automatically shut of pipes with gas or fluids. The valve has 1-1/4 inch pipe threads (internal thread, BSPP). The housing of the valve is made of brass with a hard chrome plated brass ball and PTFE (teflon) seat rings. The actuator is suitable for both 24 volt AC 50/60Hz (alternating current) and 24 volt DC (direct current). With switches on the circuit board, the actuator can be set for AC or DC. The factory default setting is direct current (DC). It is very imortant to set the actuator to AC, before using a 24V AC power supply. The actuator has a robust aluminium housing (IP67, provided that an appropriate cable is connected) and delivers maximally 20 Nm torque. The valve rotates from 0 to 90 degrees in 4 seconds. When the ball reaches an end position, the electric motor is turned off and no energy is consumed. The actuator is equipped with two additional limit switches for position-feedback. The limit switches are positioned at 0 and 90 degrees. If required, the angular position of the switches can be adjusted by the user. A mechanical position indicator on the top of the actuator shows the valve position. The actuator is equipped with a manual override.

This valve can be used in combination with gases and fluids. Some examples of compatible media are water, (compressed) air, vacuum (max -0.9 bar), oils and fuels. The brass housing is not suitable for chloride solutions (like seawater, swimming pools) or demineralized water. The maximum pressure at room temperature is 32 bar, at higher temperatures the maximum allowed temperature decreases (see figure below). The direction of pressure is not important, the direction of flow may be in any direction. The temperature range of the medium lies between -20°C and 130°C. At high temperatures, it is recommended to install the valve in a ventilated area. It is allowed to install the valve in a humid environment provided that all parts, like an appropriate electrical cable, are correctly fixed. Ball valves can be used with light contaminated fluids. Some examples of applications for this valve are HVAC, irrigation, industrial automation, water management.

The actuator works with 24 volt DC and 24 volt AC (50/60Hz). On the PCB are two small switches to set the actuator to AC or DC. The default setting is DC. Before using AC power supply, the switches on the PCB need to be adjusted first. Only use the correct power supply to prevent damage to the actuator. The actuator draws 0.2A nominally, and 1.2A at maximum torque. The actuator has 3 point control. Terminal 1 (minus) and 2 (plus) are permanently connected. Terminal 3 and 4 are control wires. Connecting one of the control wires to the minus, opens or closes the valve. Never connect both control wires at the same time to prevent short circuit and damage to the actuator. To connect the wiring to the actuator, the cover needs to be removed with four bolts. The acatuator has two internal limit switches. As soon as the end position is reached (0 or 90 degrees), the motor is switched off and no energy is consumed. Furthermore, the actuator has two extra limit switches that can be used for position feedback. If required, the angular position can be adjusted. Always connect to the ground, don't use the piping as earthing.

Make sure that the position of the ball and the actuator are properly set before assembly. The actuator is provided with two adapters to connect the actuator to the valve shaft. Mount the actuator to the valve with the provided bolts. There should be no play between both flanges. Use fittings for the connection between the pipe and the valve.
