Blowdown Valves :

Angle Pattern Single Stage and Multi stage design
The ACT x 83 Three Stage Angle Pattern Valve is Suitable for High Pressure Drain and Blow Down Service. Typical applications for this valve are Boiler Drum Continuous Blow Down and Turbine Drain Lines. These valves are designed for pressure drops as high as 200 bar.The Multistage Valve design integrates the advantages of a High Pressure Stop Valve Design and the Reliability of a High Pressure Reduction Valve. The Valve has a replaceable seat bush with stellite deposition at the seat. Slots in the seat bush and control plug are designed such that the spindle is guided throughout its travel by the seat bush eliminating the harmful effects of vibration. Velocities are restricted to 2-3 ms inside the valve when used on hot water services. The valve yoke is provided with a roller thrust bearing for ease of operation. High density pure graphite rings and roller burnishing of spindle and stuffing box bore, eliminate leakage through gland packing. Valve operation can be done by a hand wheel or with an electrical actuator without major modification to the yoke.
