STVM® Valve

Operation

During operation, cold water enters the mixing valve and moves from the inside out, while incoming steam moves from the outside in. Mixing occurs as the two flows collide, thoroughly mixing and heating the water to the desired temperature with minimal noise and vibration. Because of the unique mixing 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, eliminating operator stress, and making it ideal for workplace environments.

The unique flow characteristics of the vortices inside the valve create a scouring action that minimizes the effects of mineral deposits on valve operation, assuring increased service life even under adverse conditions. 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 (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.
