OPERATION: Therm-Omega-Tech's STVM valve uses unique vortex technology for silent operation. During operation, cold water enters the mixing valve and forms an inner vortex that moves from the inside out, while incoming steam forms an opposing outer vortex that moves from the outside in. Mixing occurs as the two vortices collide, thoroughly mixing and heating the water to the desired temperature. What's especially remarkable about vortex technology is what you don't hear - the banging, popping, and crackling noises that come from ordinary mixing valves. That means there's none of the racket that can add stress to the work environment, and none of the cavitation that can cause premature wear.

ADVANTAGES: Because of the unique vortex flow characteristics inside the STVM valve, it is capable of mixing steam and water without the usual noise and vibration associated with other types of mixers. As a safety feature, the thermal actuator in the valve outlet is designed to turn off the steam flow into the valve if the cold water flow into the valve is interrupted. The entire internal operating mechanism (AKA cartridge) of the STVM valve can be quickly and easily removed as a single assembly by simply unscrewing the valve cap. This allows easy cleaning and service without removing the valve from the line. The Unique flow characteristics of the vortices inside the valve create a scouring action that together with special coatings on the cartridge element minimize the effects of mineral deposits on valve operation, assuring increased service life even under adverse conditions.

TYPICAL APPLICATIONS: Hot water supply for: •Process hot water •Batch fill operations •Spray cleaning systems for vessels •Commercial laundry hot water •Boiler water preheating, deaerating •Other direct steam injection heating
