This strong and energy efficient 3-way (L-port) electrical ball valve from Tameson can be used to automatically shut of pipes with gas or fluids. The valve has 3/8 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)/NBR sealing. The actuator is suitable for both 12 volt AC 50/60Hz (alternating current) and 12 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 an 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.

Bore and circuit function
The ball has a L-port. By rotating the ball 90 degrees, can be switches between two circuits. The ports overlap during rotation.
