Mixing valves for evaporation purposes

Bronkhorst® mixing valves are usually supplied as an integral part of a Control Evaporator Mixer (CEM). They may also be supplied separately as a replacement part or for a particular set-up that does not require a heating chamber for complete evaporation of the liquid which is injected the carrier gas flow.
Mixing valve models W-001/W-002/W-003 have a pressure capability of 100 bar (1500 psi) and a purge connection for easy elimination of air or gas. They are directly operated by a magnetic coil with IP65 (weatherproof) housing and are closed when de-energized (Normally Closed).
