Q44F, Q45F three-way four-seal ball valve
The Q44F/Q45F three-way ball valve is available in T-type and L-type. The T-type valve allows three orthogonal pipes to connect and disconnect a third channel, serving as a flow divider or merging valve. The L-type valve can only connect two orthogonal pipes and cannot simultaneously maintain the connection of a third pipe; it only serves a distribution function.

Q44F, Q45F three-way four-seal ball valve Product Features
1. The three-way ball valve features an integrated structure with a four-sided seat sealing design, reducing flange connections, increasing reliability, and achieving lightweight design.
2. The three-way ball core is available in T-type and L-type, offering long service life, high flow capacity, and low resistance.
3. Ball valves are classified into single-acting and double-acting types. The single-acting type ensures that in the event of a power source failure, the ball valve will remain in the state required by the control system.
