"Our ASME B16.34 valves are the backbone of high-pressure fluid control systems. Designed with optimized wall thickness and premium heat-treated materials, they ensure maximum safety and durability.

• Precision Engineering: Compliant with ASME B16.34 for pressure-temperature ratings and B16.10 for face-to-face dimensions.

• Leak-Proof Performance: Available with Stellite-faced metal seats for abrasive steam service or PTFE soft seats for chemical resistance.

• Global Compliance: Suitable for projects requiring CE/PED, API, and ISO certifications.

• Versatile Media: Whether you are handling high-temperature steam or corrosive hydrocarbons, our range of ASTM A216 WCB and A351 CF8M bodies provides the perfect solution."

• Steam (High Temp): Cast Steel Body + Metal Seat (Stellite).

• Corrosive Acids: SS316L (CF3M) Body + PTFE Seat.

• Crude Oil/Gas: WCB Body + 13% Cr Trim (Trim 8).

Our API 6D Certified Ball Valves are engineered for the most demanding midstream and downstream environments.

• Reliability: Built with a Blow-out Proof Stem and Anti-Static design as standard.

• Sealing: Choose from high-grade RPTFE for general service or Tungsten Carbide Coating (TCC) for abrasive media.

• Configurations: Available in 2-Piece or 3-Piece Bolted Body, Side Entry or Top Entry designs.

• Compliance: Fully compliant with ASME B16.34 (Pressure-Temp) and ASME B16.10 (Face-to-Face)

• Export-Ready: We provide comprehensive documentation including Hydro-test reports, NDT reports (Radiography/UT), and material traceability

Our A105 Forged Steel Globe Valves are precision-engineered for applications requiring frequent throttling and positive shut-off.

• Forged Strength: Unlike cast valves, the forged body provides a dense grain structure, making it perfect for high-vibration and high-thermal-shock environments.

• Hardfaced Trim: Standard supply includes API Trim 8 (13% Cr + Stellite), ensuring resistance to erosion and 'wire-drawing' in steam service.

• Bonnet Options: Available in Bolted Bonnet for easy maintenance or Welded Bonnet for high-integrity leak prevention.

• Global Standards: Manufactured to comply with ASME B16.34 and tested to API 598 standards.

• Export Markets: We regularly supply to EPC contractors in the Middle East, Africa, and Southeast Asia.

Our industrial valves are designed to meet the rigorous demands of global piping systems. Every unit undergoes strict Hydrostatic and Pneumatic testing as per API 598 standards to ensure bubble-tight shut-off.

• Durability: Heavy-duty body construction in ASTM A216 WCB for standard service or ASTM A351 CF8M for corrosive chemical media.

•  Versatility: From Class 150 for general utilities to Class 2500 for high-pressure power plants

• Seat Integrity: We offer Renewable Seat Rings and Stellite-faced seating surfaces for abrasive media and steam service.

•  Compliance: Designed as per ASME B16.34 with face-to-face dimensions according to ASME B16.10.

• Media: Water/Oil 

• Seat: Buna-N / EPDM (Temp < 120°C)

•  Media: Chemicals/Acids Seat: PTFE / Teflon (Excellent Resistance)

• Media: Steam / High Temp 

•  Seat: Metal-to-Metal (Stellite) (Temp > 250°C)

Our Triple Eccentric Butterfly Valves are the ultimate solution for critical isolation and throttling.

•  Zero-Friction Design: The 3rd offset (conical sealing) ensures the disc only contacts the seat at the final point of closure, eliminating wear and reducing torque.

• High-Temperature Reliability: Unlike soft-seated valves, our Metal-to-Metal Stellite seats can handle up to 600°C and are ideal for high-pressure steam and refineries.

• Bi-Directional Sealing: Provides bubble-tight shut-off in both flow directions.

• Compact & Lightweight: Half the weight of a Gate Valve, reducing pipeline stress and installation costs.

• Certifications: Supplied with API 607 Fire Safe certificate and MTC 3.1 traceability.

Our Duplex and Super Duplex Stainless Steel valves are the definitive solution for aggressive chloride environments where standard 316L fails.

• Superior Metallurgy: Featuring a balanced 50/50 austenitic-ferritic microstructure for maximum tensile strength and stress-corrosion cracking (SCC) resistance.

• Extreme Reliability: Every valve is API 598 tested. Our Super Duplex 2507 range is ideal for high-pressure applications up to Class 2500.

   

• Global Standards: We supply as per ASTM A890 and ASTM A182 specifications.

•  Applications: Trusted by EPC contractors worldwide for Marine Engineering, Chemical Processing, and RO (Reverse Osmosis) Desalination units."
