RTK MV 5351-5451 / PV 6351-6451

Electric or pneumatic actuated steam converting valves

Steam-converting valves reducing the pressure while simultaneously cooling the steam. The steam pressure is reduced by a low noise perforated cone. The water is injected into the perforated cone from below and, depending on the valve stroke, the perforated cone blocks the outlet holes of the water injection pipe. This way the injected water is atomised effectively and independent of load. Available are electric (MV) and pneumatic (PV) actuated versions to achieve the neccessary operating force and speed.
