A 2-piece flanged ball valve provides reliable on/off isolation on flanged process plant piping. Furthermore, the flanged end connection allows the valve to be removed from the pipeline for maintenance or replacement by unbolting the flange joints — no cutting of welds required. Consequently, it is the standard specification for industrial process plant ball valves in chemical, HVAC, water treatment, and general industrial flanged piping systems.


2-Piece vs 3-Piece Flanged Ball Valve — When to Specify Each

Feature2-Piece Flanged Ball Valve3-Piece Flanged Ball Valve
Body ConstructionTwo body halves — one body joint — seat accessible by removing end pieceThree sections — centre body removable with both end connections remaining in pipeline
In-Line MaintenanceValve must be partially removed from pipeline for seat replacement — downstream flange joint broken✅ Centre body slides out — seat and ball replaced in-line — both flanges remain bolted to pipeline
Cost✅ Lower — fewer body components — standard for general process plant serviceHigher — in-line maintenance premium — justified for critical service lines with frequent maintenance
Specify When✅ General process plant isolation — non-critical service — infrequent maintenance — most Indian industrial and HVAC flanged ball valve applicationsCritical process lines where in-line seat replacement without pipeline disturbance is required — chemical plant critical service

Body Material Selection

Body MaterialStandardSpecify ForNot For
WCB (Carbon Steel)ASTM A216 WCB✅ Industrial process — steam, oil, gas, non-corrosive process — most economical flanged ball valve for standard Indian process plant service — Class 150 and 300Corrosive chemical, DM water, seawater — CS corrodes in these services
SS304 (CF8)ASTM A351 CF8DM water, mild chemical, food non-chloride, pharma non-GMP utility — corrosion resistant — no iron contamination — lower cost than SS316Chloride-rich service, seawater, aggressively treated water — specify SS316
SS316 (CF8M)ASTM A351 CF8M✅ Corrosive chemical, chloride service, pharma process, food GMP, seawater, coastal industrial — 2–3% Mo provides chloride pitting resistance — standard SS flanged ball valve for Indian chemical and pharma projectsGMP pharma welded piping requiring sensitisation-free material — specify SS316L CF3M

Applications in Indian Industries

Water Treatment Plants and HVAC

WCB body Class 150 flanged DN50–DN200. Chilled water, condenser water, and hot water pipeline isolation in HVAC systems. Furthermore, raw water and treated water pipeline block valves in ETP, STP, and municipal water treatment plants. Full bore design maintains pipe bore and allows pigging on water treatment plant main lines.

Chemical and Petrochemical Plants

SS316 CF8M body Class 150 and 300 flanged DN25–DN150. Corrosive chemical process line isolation — chloride-containing media, acid, alkali, solvent service. Moreover, SS316 body resists corrosive attack that WCB body cannot handle in chemical plant service. Class 300 for higher pressure chemical process lines above 20 bar operating pressure.

Oil and Gas Pipelines

WCB body Class 150 and 300 flanged DN50–DN200. Pipeline block valves, pump isolation, tank farm manifold valves. Full bore design allows pipeline inspection tools (PIGs) to pass through without restriction. Furthermore, gear operated for large bore DN150–DN200 where manual lever torque is too high for comfortable operation.

Fire Fighting Systems

WCB body Class 150 flanged DN65–DN200. Fire hydrant main supply isolation, sprinkler zone valves, deluge system isolation. Lug type available for dead-end service at fire hydrant termination. OS&Y (outside screw and yoke) version available for fire fighting applications where open/closed position must be visually confirmed from a distance.

Frequently Asked Questions

1. What is the difference between 2-piece and 3-piece flanged ball valve?

A 2-piece ball valve has one body joint — the end piece is removed for seat access, which requires breaking the downstream flange joint. A 3-piece ball valve has three sections — the centre body slides out for in-line seat replacement while both flanged end connections remain bolted to the pipeline. Specify 2-piece for general process plant service where in-line maintenance is not required. Specify 3-piece for critical process lines where seat replacement must be done without pipeline disturbance.

2. What pressure class should I specify — Class 150 or Class 300?

Class 150 (approximately 20 bar at ambient for WCB, 19 bar for SS316) covers the majority of Indian industrial process plant and HVAC flanged ball valve applications. Specify Class 300 (approximately 51 bar at ambient) when operating pressure plus test pressure exceeds Class 150 rating, or when the project piping class explicitly specifies Class 300. Always confirm from the project piping class document before ordering.

3. What flange facing is standard?

Raised face (RF) is the standard for ASME B16.5 Class 150 and 300 flanged ball valves. RF concentrates bolt load on the raised ring and provides reliable sealing with a spiral wound or ring gasket. Flat face (FF) is required only when connecting to cast iron flanges — specify FF only if the mating flange is cast iron.

4. What is the MOQ?

MOQ is 10 Nos. Project and plant orders — 10 to 500+ Nos across sizes and body materials — with API 598 test certificate, MTC for SS grades, and GST invoice. WhatsApp body material, size list, pressure class, and quantity for project pricing within 2 hours.
