Inner thread 3 way electric ball valve
Product introduction
COVNA electric 3 way ball valve according to the structure can be divided into L-type and T-type, and T-type has four kinds of directions, L-type has one type direction, can be come true: Reversing, shunt, combined, mixed flow effect. Match with electric actuator and pneumatic actuator can realize automatic control. 3 way ball valve seat material has: PTFE, PPL, hard steel, suitable for temperature range of 180-380 degrees. Please kindly note the 3 way flow directions when order.
