A válvula globo de aço fundido é projetada de acordo com a BS 1873 e normalmente é usada onde são necessárias operações frequentes de abertura e fechamento, bem como controles de fluxo em qualquer grau desejado. As válvulas globo de aço fundido são caracterizadas principalmente pelo formato globo do seu corpo.

BS 1873 cast steel globe valve is the most appropriate manual valve and used in flow control when it is necessary to control the flow or pressure of a certain type of fluid, but cast steel globe valve is not a bi-directional valve, cast steel globe valve allow an efficient regulation of the fluid, with minimal erosion wear, both in the seat and in the plug, in contrast, they offer high pressure loss due to the sudden change of direction imposed on the fluid.

SPECIFICATION:
● Size: 2”~24”
● Classificação de pressão: Classe 150~2500LB
● Main Materials: WCB, WCC, WC6, LCB, CF8, CF8M, CF3, CF3M, 4A etc.

FEATURE:
•Manufacturing acc.to API 600,BS 1873
•Straight Patterns, Angle Patterns
•OS&Y, Outside Stem & Yoke, Bolted Bonnet, Pressure Seal Bonnet
•End flange to ASME B16.5 (2” to 24”) ASME B16.47 (26” & up) Butt-Weld End Dimension ANSI/ASME B16.25
•Forged Steel, Cast Steel, Stainless Steel, Alloy Steel, Bronze, Duplex, Super Duplex Steel , etc.
•Back seat facilities provide easy replacement of gland packing under pressure.
•Extra deep stuffing box ensures fluid tightness, long packing life and low emissions.
•Suitable for thermal fluid temperature up to 425º c
•Check valves for two-port valves (entry and exit of fluid).
•Inspection & Testing: API598

ADVANTAGE:
– Allow partial flow control;
– Opening and closing faster than gate valves;
– The constructive characteristics of the seat-shutter assembly allow total tightness;
– Maintenance favored by easy access to the internal components of the valve, without removing it from the line.

DISADVANTAGE:
– Do not admit flows in both directions;
– High head loss.
