KRS Feed Water Heater By-pass Valves(Sales No.:1421)
Feed Water Heater By-pass Valves(Sales No.:1421)FEATURES & BENEFITS These PV DBS Series Feed Water Heater Isolation Systems valves are designed to bypass high pressure feed water around a group of heaters in the event of high water level in the shell caused by a defective tube, weld or drain system. The time available to give protection to a turbine in modern feed systems is short but these valves can operate in approximately 5 seconds in a 300mm bore pipe system with the minimum of hydraulic shock. Protection is achieved in the system by installing fast closing tee and changeover valves in the pipe-work around a heater or group of heaters. These valves are equally applicable in new or established stations. The motive power employed is the feed-water pressureand the system is designed to “fail safe” in that the heaters will be by-passedif either electric or pneumatic supplies fail. ...
