Severe service valves Boiler Feedpump Recirculation Valve

China Steam Pressure Reducer, China Steam Pressure

The severe service steam pressure reducing valve reduces the high pressure steam, while the desuperheater reduces the overall temperature of the steam. Temperature reduction is essentially a matter of heat transfer, where the cooling water is placed in direct contact with steam and receives the necessary heat for evaporation.

BOILER FEEDPUMP RECIRCULATION - UECcontrol

2013-6-19 · Therefore, the boiler feedpump recirculation valve will be in the closed position for 90% to 95% of the time in most power plants. This valve will also have the highest differential pressure across the seat of any other valve in the plant. This makes the recirculation valve one of the most severe duty valves in a generating plant.

Limiphon - 1-9000 - Valve by Parcol S.p.A.

Specifically studied for severe service applications, LIMIPHON valves were designed and built by Parcol in 1971. Based on the concept of multi-path and multi-stage labyrinths (velocity controlled trim), LIMIPHON trim divides flow into many streams to minimize the energy levels and it is the ideal solution for all those applications where high pressure drops are the main cause of noise
