STEAM CONDITIONING VALVE HCVAC1
25 - 300
HCVAC1 steam conditioning valve combines pressure and temperature control in a single valve and is commonly used in process steam systems.
HCVAC1 is straightway valve. It incorporates a spraywater manifold and atomizing steam implementation downstream of its pressure reduction stage. Its pressure-reducing device (steam sparger) is regulatory valve with perforated plug (with a stem driven through guide bushing) and slip-in seat fixed by construction cage. A medium undergoes multistep expansion. Firstly, the expansion occurs on the perforated plug itself. Next steps are up to throttling plates fixed at the valve’s outlet. Their number coincides with the given work characteristics of the valve. Water injection follows the complete steam expansion. Drilled stem feeds the atomizer with steam entering pressure-reducing portion of the valve. The occurrence of smaller droplets permits the water to remain suspended and its almost immediate absorption by the steam’s stream. Any control of coolant’s flow demands an implementation of additional injection valve.
