Q44H, Q44Y, Q45H, Valvole a sfera a tre vie Q45Y a tenuta rigida
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.
