What Are Valves?
Per ASME B16.34 and API 600/602, industrial valves control the flow, pressure, and direction of fluids in piping systems. They perform three functions: isolation (on/off), throttling (flow regulation), and non-return (backflow prevention). Bodies are cast (API 600, 2" and above) or forged (API 602, up to 4"). Pressure classes span 150# to 2500# per ASME B16.34. We supply gate, globe, ball, check, and butterfly valves for industrial and oil & gas service.
- Gate valves: Full-bore isolation, minimal pressure drop (API 600/602)
- Globe valves: Precision throttling and flow regulation (API 623)
- Ball valves: Quarter-turn operation, bubble-tight shutoff (API 608)
- Check valves: Automatic non-return to prevent backflow (API 594)

Applicable Standards & Specifications
How To Order
- Specify valve type (gate/globe/ball/check/butterfly), size (NPS), pressure class, and material.
- Indicate end connection — flanged (RF/RTJ), butt-weld, socket-weld, or threaded.
- State actuation requirement — handwheel, gear-operated, pneumatic, or electric actuator.
- Approve quotation and PO — we dispatch from Kanpur stockyard or coordinate mill supply.
Frequently Asked Questions
What is the difference between gate and globe valves?
Gate valves provide full-bore isolation with minimal pressure drop when fully open — they are either fully open or fully closed and should not be used for throttling. Globe valves have a disc-and-seat design that allows precise flow regulation and throttling. Use gate valves for on/off isolation and globe valves when you need to control flow rate.
What pressure classes are available?
Industrial valves are available in ASME B16.34 pressure classes: 150#, 300#, 600#, 900#, 1500#, and 2500#. The required class is determined by the system design pressure and temperature. 150# covers most utility and water applications, while 600# and above are common in refinery and high-pressure oil & gas service.
Do you supply actuated valves?
Yes, we supply valves with pneumatic, electric, and hydraulic actuators for remote or automated operation. We work with leading actuator manufacturers to provide complete valve-actuator assemblies tested and ready for installation. Manual options include handwheel and gear operators for larger sizes.
