This strong and energy efficient 2-way electrical ball valve from Tameson can be used to automatically shut of pipes with gas or fluids. The valve has 2-1/2 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)/FKM sealing. The actuator is suitable for both 24 volt DC (direct current) and 24 volt AC 50/60Hz (alternating current). With switches on the circuit board, the actuator can be set for AC or DC. The factory default setting is direct current (DC). The actuator has a robust aluminium housing (IP67, provided that an appropriate cable is connected) and delivers maximally 40 Nm torque. The valve rotates from 0 to 90 degrees in 8 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.
