Equipment and spare partsBrowse manufacturers Search by manufacturerDirect factory export of heavy-duty industrial valves manufactured by Zhejiang Led Valve Co., LTD (Wenzhou, China). Turnkey fluid control packages for oil & gas, petrochemical, power generation, and marine industries: API 600 / DIN / GOST wedge gate valves, API 6D trunnion and floating ball valves, BS 1873 globe valves, API 594 non-return check valves, API 609 triple offset metal-seated butterfly valves, ASME B16.34 pipeline strainers, and API 602 high-pressure forged steel valves.
CNLD wedge gate valves provide robust, bi-directional isolation for critical oil, gas, chemical, and steam pipelines. Featuring an outside screw and yoke (OS&Y) design, flexible wedge disc with Stellite hardfaced seats, and bolted bonnet or pressure seal bonnet construction. Available from DN50 to DN1200 (2" to 48") with ASME pressure classes 150 through 2500. Cryogenic versions with extended bonnets operate reliably down to -196 deg C.
CNLD API 6D ball valves are engineered in split-body 2-piece/3-piece trunnion-mounted designs for pipeline duty and compact floating designs for plant piping. Incorporating true Double Block & Bleed (DBB) cavity relief, spring-energized seats with soft (PTFE, PEEK, Devlon) or tungsten carbide coated metal-to-metal seating. Engineered to withstand sour gas (NACE MR0175), hydrocarbon transport, and cryogenic LNG service.
CNLD globe valves are precision-crafted for throttling, regulating, and bubble-tight isolation of steam, thermal oil, gases, and corrosive chemicals. The portfolio features standard straight-pattern bolted bonnet valves, high-pressure pressure seal bonnets, low-pressure-drop Y-pattern configurations, and zero-emission bellow seal valves engineered to contain hazardous and toxic process media.
CNLD non-return check valves provide automatic backflow prevention and water hammer protection for pumps, compressors, and pipeline networks. The comprehensive line includes full-bore swing check valves, vertical lift check valves, rapid-closing non-slam tilting disc check valves, compact dual-plate wafer check valves, and counterweight hydraulic cushioned swing models.
CNLD triple offset butterfly valves deliver premium zero-leakage, bi-directional shut-off as a lightweight, cost-effective replacement for gate and ball valves in large-bore piping. The triple eccentric geometry eliminates seat friction during stroke, ensuring ISO 5208 Rate A seal integrity across temperatures from -196 deg C to +550 deg C. Available in wafer, lug, double-flanged, and butt-weld body patterns.
CNLD pipeline strainers effectively capture solid contaminants, scale, welding debris, and particulate matter, shielding downstream pumps, meters, control valves, and turbines. The line includes compact Y-type strainers for horizontal/vertical piping, T-type strainers for compact footprints, and high-capacity basket strainers featuring quick-opening covers for rapid basket extraction and cleaning.
CNLD forged steel small-bore valves are drop-forged from homogeneous steel billets, ensuring dense microstructure, superior tensile integrity, and resistance to thermal shock and mechanical vibration. The API 602 lineup comprises compact gate, globe, and piston/ball lift check valves engineered for high-pressure steam headers, instrumentation bypasses, boiler drains, and sampling lines.
To achieve seamless distributed process automation and remote SCADA control, CNLD supplies factory-tested automated valve packages with ISO 5211 direct-mount adaptation. Options include explosion-proof multi-turn and quarter-turn electric actuators (ATEX / IECEx certified), pneumatic rack-and-pinion and scotch-yoke actuators with 4-20mA smart electro-pneumatic positioners, and heavy-duty enclosed manual gearboxes.
Our valve application engineers perform comprehensive flow coefficient (Cv/Kv) sizing, cavitation analysis, and aerodynamic noise calculations for complex fluid pipelines. We match exact metallurgy to process severity: carbon steel WCB, low-temperature LCC/LF2, austenitic stainless CF8M/CF3M, Duplex 2205/2507, nickel superalloys (Inconel, Monel, Hastelloy), and aluminum bronze C95800 for offshore seawater service.
CNLD valves are field-proven across global upstream gathering, high-pressure natural gas transmission, petrochemical refining, thermal power stations, and chemical plants. CNLD gate, ball, and globe valves deliver long-term bubble-tight sealing under severe thermal cycling, steam service, and abrasive slurry conditions.
Zhejiang Led Valve Co., LTD operates an advanced in-house casting foundry, ensuring strict spectroscopic melt control and defect-free body castings. Valve components undergo precision CNC machining, radiographic/ultrasonic NDT inspection, and 100% pressure testing in accordance with API 598, ASME B16.34, and ISO 5208 standards.
All CNLD industrial valves are exported directly from the Wenzhou manufacturing complex in rugged seaworthy wooden crates, complete with EN 10204 3.1 material test reports and hydrostatic test logs. We provide full 12-month manufacturer warranty, lifetime spare parts supply (gaskets, stems, seal kits), and integrated global logistics.
