There are T-shaped (Q45F) and L-shaped (Q44F) three-way flange ball valves, including pneumatic three-way flange ball valves and electric three-way flange ball valves. T-shaped can connect three orthogonal pipelines and cut off the third channel, playing a role in diversion and merging. L-type can only connect two pipes that are orthogonal to each other, and cannot maintain the interconnection of the third pipe at the same time. It only plays a role in distribution.
Product features of three-way ball valve
1. The three-way ball valve adopts an integrated structure in terms of structure, with a sealing type of 4-sided valve seats, few flange connections, high reliability, and lightweight design
2. The three-way ball core is divided into T-shaped and L-shaped, with a long service life, high flow capacity, and low resistance
3. Ball valves are divided into two types: single acting and double acting. The characteristic of single acting is that once the power source fails, the ball valve will be in the state required by the control system.
