As oil & gas transmission, fine chemical, hydraulic energy industries raise higher standards for high-pressure shut-off valves, cast ball valves are gradually phased out due to poor pressure resistance and leakage risks. Forged steel 3-piece ball valves become mainstream for industrial pipelines with high-strength body and detachable maintainable design. Founded in 2009, J-VALVES owns standardized forging & machining workshop, fully self-produces 3-piece ball valves, strictly controlling pressure resistance, sealing and service life from raw materials.
1. Self-owned forging workshop eliminates casting defects
Equipped with CNC forging presses & medium-frequency heating lines, we forge valve bodies with A105, LF2, CF8M, WCB forged steel as one-piece blank. Split 3-piece body components are precision forged with uniform metal density, suitable for Class150~Class250 high pressure and cryogenic service without body cracking. All finished valves in our workshop adopt uniform black anti-corrosion coating, with blue plastic protection on threaded & welded ends for consistent dimensional accuracy in mass production.
2. CNC precision machining meets API 6D sealing standard
Full set of CNC lathes and ball grinding machines inside workshop deliver mirror polished ball with Ra≤0.2μm finish. Multiple seat materials including PTFE, RPTFE and metal hard seal are available. All valves pass hydrostatic & air leakage test before delivery with test records reserved, complying with API 6D for global oil & gas projects.
3. Modular flexible workshop for bulk stock & custom orders
Our workshop is divided into forging, machining, assembly testing and finished goods storage zones. Standard NPT threaded forged 3-piece ball valves (DN6-DN100) are always in stock. Custom solutions like extended handles, anti-static structure, lockable lever, long weld ends & cryogenic alloy bodies are supported. Bulk overseas orders can be finished within 7-15 days for global contractors & valve distributors.
4. Full in-house anti-corrosion treatment for export shipping
All forged bodies receive phosphating & black oxide coating inside workshop, galvanized carbon steel handles, full blue thread caps and independent pearl cotton packaging, avoiding rust & damage during long sea transportation, solving export valve loss problems.
1. Central Asia Natural Gas Transmission Pipeline Project
Requirement: Low temperature high pressure threaded 3-piece ball valves with H2S resistance, 1200 units bulk order.
J-VALVES Workshop Solution: LF2 cryogenic forged steel body, metal hard seal, anti-static explosion-proof design. Mass production finished within 45 days with third-party pressure certification, leak-free operation for over 5 years on site.
2. Southeast Asia Coal Chemical Fine Chemical Plant
Requirement: CF8M stainless steel 3-piece weld ball valves for strong acid & alkali medium, 860 units.
Workshop Delivery Advantage: Self-owned stainless steel forging line, corrosion resistant metal sealing body, on-site detachable maintenance without full valve replacement, cutting customer after-operation cost greatly.
3. Long-term Supply for European & American Hydraulic Distributors
Overseas valve resellers purchase A105 threaded 3-piece ball valves monthly. Our workshop stable monthly output reaches 5000 stock units with standardized export packing, separate shipment available, over 90% repurchase rate in 14-year cooperation.
Most valve traders outsource cast blanks for assembly with unstable quality. Since 2009, J-VALVES operates closed-loop forging & machining workshop, controlling every step from raw material inspection to finished valve testing. We supply full material certificates, test reports & API certification documents for global engineering, machinery OEM & export distribution.
