A Forged Ball Valve Class 800# is the standard small bore high-pressure isolation valve for Indian oil and gas, refinery, petrochemical, CGD network, power plant, and chemical plant piping. The forged body — manufactured by compressing a solid steel billet under high mechanical force — eliminates the porosity and micro-defects common in cast construction, delivering superior tensile strength, fatigue resistance, and pressure integrity at Class 800# and above.
Krishna Industries, trading as KELOR Valves, supplies Forged Ball Valves Class 800# from Ahmedabad, Gujarat — ASTM A105 (carbon steel), A182 F304 (SS304), and A182 F316 (SS316) body — BSP screwed / NPT screwed / socket weld (SW) end connections — 3-piece full bore and reduced bore — PTFE and RPTFE seat — API 602 / ASME B16.34 / BS 5351 design — API 598 tested — blowout-proof stem — antistatic feature — GST invoice — MOQ 10 Nos — Pan India dispatch.
Critical note: ASME B16.34 Table 2 mandates forged body construction for Class 800# and above — a cast body valve cannot be pressure-rated at Class 800# per the code. When your project specification calls for Class 800# SW or screwed ball valves, forged body is not a choice — it is a code requirement.

Forged vs Cast Ball Valve — Why Class 800# Must Be Forged
| Parameter | Forged Body (Class 800# — This Page) | Cast Body (Class 150–600 — General Service) |
|---|---|---|
| ASME B16.34 Table | ✅ Table 2 — Forged body — mandatory for Class 800# SW / screwed / BW end connections — code requirement, not an option | Table 1 — Cast body — Class 150 to 600 flanged process plant — adequate for general service |
| Manufacturing | Solid steel billet compressed under high force — grain structure refined and aligned — near-zero porosity | Molten steel poured into mould — coarser grain — potential micro-voids during solidification |
| Tensile Strength | ✅ 125 ksi (860 MPa) for A105 ≤2½” — 15–20% stronger than equivalent cast grade | Lower tensile strength for same nominal material grade |
| Porosity | ✅ Near zero — forging closes micro-defects — mandatory for high pressure service where porosity is a safety risk | Possible micro-voids — acceptable for Class 150–600 where operating stress is lower |
| End Connection | ✅ BSP screwed / NPT screwed / Socket Weld (SW) / Butt Weld (BW) — small bore high pressure connections | Flanged ASME B16.5 — standard for process plant piping DN50 and above |
| Specify When | ✅ Any project specification citing Class 800# SW or screwed ball valve — oil and gas, CGD, refinery, power plant, chemical plant small bore high pressure isolation | Class 150–600 flanged process plant piping — general industrial service |
End Connection Selection — BSP vs NPT vs Socket Weld
| End Connection | Thread Standard | Specify When | Note |
|---|---|---|---|
| BSP Screwed | BS 21 (BSPT) | ✅ Most common in Indian industrial utility and instrument piping — matches BSP threaded pipe fittings used on majority of Indian site fabricated small bore piping | BSP and NPT are NOT interchangeable — BSP has a different thread angle (55°) from NPT (60°) — confirm thread standard before ordering |
| NPT Screwed | ASME B1.20.1 | When project piping specification explicitly calls for NPT — common on projects following American standards (ASME B31.3 with NPT fittings), instrument connections on American-designed process units | Do not mix BSP and NPT threaded components — thread forms are incompatible and will leak |
| Socket Weld (SW) | ASME B16.11 | ✅ Critical process lines where leak-free permanent welded connection is required — oil and gas wellhead, CGD metering station, refinery high pressure utility — SW eliminates threaded joint leak risk in flammable fluid service | SW is a permanent welded joint — specify 3-piece body for SW connections in critical lines where in-line seat replacement without rewelding may be required during plant life |

Key Technical Features
- READY STOCK 15mm–50mm A105 — dispatch within 2–3 working days — most competitors are 3–6 weeks make-to-order
- 3-Piece body — in-line maintenance — centre body slides out for seat and ball replacement while both end connections stay in pipeline — mandatory for SW connections in critical lines
- Blowout-proof stem — SS316 stem retained by body shoulder per API 602 and BS 5351 — prevents stem ejection under high pressure
- Full bore option — pipeline bore maintained through valve — no pressure drop — allows pipeline inspection tools (PIGs) to pass
- PTFE Class VI seat — zero leakage shut-off — critical for flammable fluid isolation in oil and gas and chemical plant service
- Antistatic feature — standard — carbon-filled PTFE seat and graphite packing ensure electrical continuity — prevents static discharge in flammable fluid service
- Fire safe design — metal-to-metal seat backup — prevents downstream leakage when PTFE seat burns away in fire conditions
- ASME B16.34 Table 2 compliant — forged body mandatory for Class 800# — not a cast body with Class 800# rating stamp — genuine forged construction

Frequently Asked Questions
Why must Class 800# ball valves have a forged body — can a cast body be Class 800#?
No — ASME B16.34 Table 2 specifically lists pressure-temperature ratings for forged bodies at Class 800# and above. A cast body valve cannot be pressure-rated at Class 800# per this code. When a project piping class or procurement specification calls for Class 800# socket weld or screwed ball valves, the forged body is not optional — it is a code requirement. Any supplier offering a “Class 800# cast ball valve” is either misrepresenting the rating or supplying a non-code-compliant valve. Always verify the body is genuinely forged — request the MTC (material test certificate) confirming ASTM A105 forged grade.
What is the difference between BSP and NPT threaded forged ball valves?
BSP (British Standard Pipe — BS 21) and NPT (National Pipe Taper — ASME B1.20.1) are two different thread standards. BSP has a 55° thread flank angle while NPT has a 60° thread flank angle — they are NOT interchangeable. A BSP valve screwed into an NPT fitting will appear to thread but will not seal — the threads cross and leak under pressure. In India, BSP is the most common standard for general industrial and utility small bore piping. NPT is specified on projects following American standards (ASME B31.3 with NPT fittings) or on American-designed process units. Always confirm the thread standard from your project piping specification before ordering. When in doubt, WhatsApp a photograph of your existing pipe end or fitting for confirmation.
When should I specify socket weld instead of screwed end?
Specify socket weld (SW) when the valve is on a critical process line carrying flammable, toxic, or high-pressure fluid where a threaded joint leak is unacceptable. Socket weld is a permanent welded joint — the pipe end is inserted into the valve socket and fillet-welded around the outside — creating a leak-free metallic joint. Screwed (BSP/NPT) ends are suitable for utility lines, instrument connections, and service lines where the valve may need to be removed for maintenance and where a small amount of thread compound leakage is acceptable. For CGD metering stations, refinery critical process lines, and oil and gas wellhead piping, SW is typically the mandatory end connection per the project piping class.
What is the advantage of 3-piece body over 2-piece for a Class 800# ball valve?
In a 3-piece forged ball valve, the centre body with ball and seats slides out while both end connections remain in the pipeline. For socket weld connections — which are permanent welds — removing the valve from a 2-piece body requires cutting the weld, welding in a new valve, performing NDT on the new weld, and PWHT if required. This is expensive and time-consuming. A 3-piece body allows seat and ball replacement in-line without cutting any weld — the two welded end sockets stay in the pipeline while the centre body is serviced. This is the primary reason 3-piece forged ball valves are the standard specification for critical SW connections in refineries, gas plants, and chemical plants where the valve will need seat maintenance during the plant’s operating life.
What does ready stock mean — what sizes and grades are immediately available?

EN 10204 3.2 MTC (third party witnessed by TUV / BV / Lloyd’s) is available at buyer’s cost for export orders and EPC project documentation requiring independent material certification. For NACE MR0175 sour service applications, restricted hardness certificates are available — specify at order stage.
What is the MOQ?
MOQ is 10 Nos per size per end connection per grade. Mixed orders across sizes (½” + ¾” + 1″ + 1½” + 2″), end connections (BSP + SW), and grades (A105 + F316) are welcome in a single purchase order with one GST invoice and documentation package.
