Q44H, Q44Y, Q45H, Q45Y hard seal three-way ball valves

Hard-seal three-way ball valve type code: Q indicates ball valve; Connection type code: 4 indicates flanged type; Structural type code: 4 indicates L-shaped tee, 5 indicates T-shaped tee; Sealing surface material code: H indicates stainless steel, F indicates fluoroplastic; Valve body pressure code: 16 indicates 16 kg; Valve body material code: C indicates carbon steel, P indicates 304 stainless steel, R indicates 316 stainless steel; Related models of Q44/Q45 three-way ball valves: Q44F-16C, Q44F-16P, Q44H-16C, Q44H-16P, Q44H-16R, Q45H-16C, Q45H-16P, Q45H-16R, Q45F-16C, Q45F-16P

Q44H, Q44Y, Q45H, Q45Y hard seal three-way ball valves

The Q44H/Y and Q45H/Y hard-seal three-way ball valves are 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.
