BS1873 GLOBE VALVE 8inch 600lb WCB BODY GEAR TRIM WCB+Stellite RF FLANGE
Design Features:
Designed for least possible obstruction to free flow by providing
curvature turns in the body thereby minimising stresses &
turbulence. The plug & seat-ring are machined and lapped very
precisely to get a very tight sealing when valve is closed.
Designed and manufactured to the highest standards of quality and,
durability.
Applications:
Petroleum, Power Generation, Chemicals, Fertilizers, Steel
Industry, Natural Gas/Fuel Oil Control, Steam Control and Feed
Water Control.
Operators: Handwheel, Chainwheel, Gear Electrical Actuator, Pneumatic/Hydraulic, Actuator Operated.
Special Features: Pressure Sealed Joints/Double Block and Bleed/Cryogenic Service to BS 6364/Nace Specifications (MR-01-75), Regulating Discs for Throttling Service, Double Disc, Bypass Arrangement.

| Globe Valve | Precision Finish Seat & Surface
• Fire Safe Design • Rotating Tip • Linear or Equal • % Characteristic • Back Seat Arrangement • Pressure Seal Bonnet • Low Torque Quick Opening | • Good shut-off capability
• Moderate to good throttling capability • Shorter stroke (compared to a gate valve) • Easy to machine or resurface the seats • With disc not attached to the stem, valve can be used as a stop-check valve. | • Fuel oil system where flow is
regulated and leak tightness is of importance. • High-point vents and low-point drains when leak tightness and safety are major considerations. • Boiler vents and drains, main steam vents and drains, and heater drains. |
