Control vaves DN 25 to 150, PN 16 to 160, Kvs 1,6 to 250 m3/h

Description
Control valves type RV504 are three-way valves with mixing or diverting function. Due to the pressure unbalanced execution, it is necessary to take into account a max. differential pressure for a given size. Flow characteristics, Kvs values and leakage rates correspond to international standards.
The valves can be delivered with flanges or weld ends having faces acc. to the customer´s requirements and demands. In case of a service or replacement of bottom seat of a valve with weld ends execution it is always necessary to cut out a valve from a pipeline and weld up back.
