Ball valve VS series

electricmixingfor water

VS series 3-way mixing valves with bypass are available in DN15, DN20, and DN25 sizes, for use in compact zone valve applications. VS_F series is available in DN15, DN20, and DN25 size, with external pipe thread, flat seal, and four pipe connections for maximum piping flexibility. Two pipe connections on the B-port allows for both supply and return pipes to be piped in parallel. An impressive range of KVS values are available, to suit a wide range of applications. 2.5mm stroke valves are available for 2-P on/off control, as well as 6.5mm stroke versions for modulating control. Valves are used with compact thermo-electric and electric actuators for a compact assembly. Flow characteristic for 6.5mm stroke valves is equal percentage on the A-port, and linear on the B-port (with one size smaller KVS value for optimum control). Valve action: A-port is open with the stem in its bottom position.
