Casted & Forged Globe Valves
Precision throttling and flow regulating valves conforming to BS 1873 (Casted) and API 602 / BS 5352 (Forged Steel). Designed with parabolic plug discs, outside screw & yoke (OS&Y), renewable Stellite hard-faced seats, and bolted or pressure-seal bonnets rated from Class 150 up to Class 2500.
Engineered for Accurate Flow Throttling, High Velocity & Extreme Temperature Service
ENGIPRO SOLUTIONS LLP manufactures precision Casted Globe Valves (BS 1873 / ASME B16.34) and Forged Steel Globe Valves (API 602 / BS 5352 / ISO 15761) engineered to deliver superior throttling and positive shut-off in critical process pipelines. Designed with linear globe body geometry and finely contoured parabolic plug discs, these valves provide predictable flow regulation with excellent resistance to cavitation, wire drawing, and high-velocity erosion.
Our Casted Globe Valves (2" to 24") feature heavy wall sections in ASTM A216 WCB, A352 LCB/LCC, and stainless alloys, fitted with renewable Stellite hard-faced seat rings and precision-guided disc stems. Forged Globe Valves (1/2" to 2" in Class 800/1500/2500) provide exceptional metallurgical strength in ASTM A105, A350 LF2, chrome-moly F11/F22, and duplex alloys, equipped with bolted, welded, or pressure-seal bonnets.
Widely installed across power plant boiler feedwater systems, superheated steam extraction, chemical reactors, refining bypass manifolds, and oil & gas terminals. Every valve is 100% hydrostatically and pneumatically tested in accordance with API 598 and BS EN 12266-1.
Special Features & Engineering Construction
Engineered to comply with BS 1873, API 602, and ASME B16.34 requirements for throttling accuracy and high-pressure steam integrity.
Plug Type Regulating Disc
Contoured parabolic plug disc provides wide seating contact and linear throttling characteristics, resisting wire drawing under high differential pressures.
OS & Y Rising Stem
Outside screw and yoke keeps actuator threads isolated from the hot process stream, with visual position indication via the rising stem.
Renewable Stellite Trim
Hard-faced with Cobalt-base Stellite Gr. 6 (API Trim 5 / 8 / 12) for extreme erosion resistance against high-velocity superheated steam.
Pressure Seal Bonnets
Offered in both Bolted Bonnet and Pressure Seal Bonnet construction where higher internal pressure wedges the gasket tighter for Class 900 to 2500.
Integral Backseat Design
Precision-machined backseat collar seals the stuffing box when fully open, reducing stem packing pressure and enabling safe online maintenance.
Versatile End Connections
Available in Flanged Raised Face (RF), Ring Type Joint (RTJ), Butt Weld (BW), Socket Weld (SW), and Screwed (NPT/BSPT) pipe connections.
NACE MR0175 Compliance
Heat-treated metallurgy, controlled base hardness, and NACE-certified packing and gasket materials designed specifically for sour gas and oil services.
Linear & Rotary Actuation
Compatible with standard handwheels, bevel gears, linear pneumatic diaphragm actuators, and electric modulating multi-turn control drives.
