Pistons - Import export

Jet Flow multi orifice desuperheater regulates the amount of injected water by varying the number of orifices during operation. The ensures that the spray water pressure remains constant at all loads and an excellent and almost uniform spray quality is achieved over the full operating range, thereby minimising the tendency of spray water to accumulate in the steam line. Opening of the orifices is regulated by the positioning of a piston operated actuator directly mounted on the desuperheater. This compact and simple design ensures no separate spray water Injection control valve is required.

Turbine bypass valves play a very major role in Power Plant applications. Within a short period of twenty four hours, a power plant may be required to operate at minimum load, increase to maximum capacity for major part of the day, immediately lower back to minimum load and then back to maximum capacity. Bypass System permit unit start up and shutdown in a lifesaving manner for critical heavy components in boiler and turbines. Jet Flow Bypass valves are supplied with hydraulic, electric or pneumatic actuators as per the process requirements alongwith complete control systems as an option.
