Fisher Controls Boiler Feedwater Startup Valves Simple Type: Boiler Feedwater Startup Valve
In the normal range of plant operation, the boiler feedwater regulator experiences high flow rates with low differential pressure. However, during startup, this valve experiences low flow rates with very high differential pressure, which can cause severe cavitation damage. Some feedwater systems are designed using one valve to handle startup and normal operating conditions. Others are designed using a separate small startup valve to handle low flow, cavitating conditions and a second larger valve to handle high flow rates required for normal operation. Fisher feedwater startup and regulator valves are engineered to eliminate cavitation during initial operation and provide the rangeability required for smooth transition from startup through full load operation.

Features
- Advanced sealing technology provides tight shutoff and extends service life.
- Characterized cage provides low-flow cavitation protection during initial operation and necessary flow as pressure rises.
- High turndown handles extreme flow rates.
- One valve solution: offers anti-cavitation protection during low flow, high pressure drop startup, and unrestricted high flow during low pressure drop, full load conditions.
- Optional trim allows passing of 19 mm (.75 inch) particulate.
- Pneumatic piston actuator provides highly accurate step positioning and stable valve response.
- Two valve solution: offers a dedicated startup valve to handle cavitating conditions in parallel with a larger standard trim valve, handling full load conditions.
