Qingdao Judberd Machinery Co.,Ltd.
About
Qingdao Judberd Machinery Co., Ltd. (brand: JUDBERD) is a Chinese ductile iron pipe fitting and valve manufacturer with over 30 years of experience, operating from Qingdao with a primary foundry and a second facility (Gaomi Judberd Pipe Fitting Co., Ltd., established 2020). The company maintains in-house casting, polishing, machining, coating, and assembly workshops and is a qualified vendor for international brands including Hawle and Saint Gobain. Judberd's product range spans ductile iron pipe fittings compliant with EN 545, EN 598, ISO 2531, and AS/NZS 2280; pipe joints including dismantling joints (with mild steel variants featuring penetration-tested welds and epoxy glass flake or rubber-lined options for seawater service), flexible couplings (including mechanical couplings for HDPE), flange adaptors, saddle clamps, and gibault joints; and a comprehensive valve lineup covering resilient and metal-seated gate valves (NRS and OS&Y configurations), check valves (ball, swing, silent, wafer, tilting disc, foot), butterfly valves (wafer, lug, flanged), air release valves, pressure reducing valves, and knife gate valves. Supplementary products include Y strainers, basket strainers, flow straighteners, flap valves, surface boxes, repair clamps, tapping sleeves, and rubber expansion joints. The company holds ISO 9001, WRAS, ACS, DVGW, NSF, UL/FM, and CE certifications and offers both OEM and ODM services.
Key Products
Cast iron fittings for water and wastewater pipeline connections compliant with European and international standards.
Adjustable pipeline connectors that allow for easy installation and removal of valves and fittings in water mains.
Flexible connectors that accommodate angular deflection and pipe movement in water and sewer pipelines.
Transition connectors that join plain-end pipes to flanged valves or fittings in pipeline systems.
Branch connection fittings that allow tapping into existing water mains for service line connections.
Mechanical joints for connecting plain-end ductile iron pipes in water distribution networks.
Shut-off valves with rubber-coated wedges for bubble-tight sealing in water supply pipelines.
Gate valves with metal-to-metal seating for high-temperature or abrasive fluid service conditions.
Non-return valves using a ball mechanism to prevent backflow in pumping stations and pipelines.
Non-return valves with a hinged disc that swings open with forward flow and closes to prevent reverse flow.
Non-return valves with spring-loaded discs that close quickly to eliminate water hammer in pump discharge lines.
Compact non-return valves designed for installation between flanges in tight-pipeline spaces.
Non-return valves with a tilted disc design that reduces slam and water hammer in large-diameter pipelines.
Non-return valves installed at the inlet of suction pipes to maintain pump prime in water supply systems.
Quarter-turn shut-off valves with a disc that rotates between flanges for flow control in pipelines.
Butterfly valves with threaded lugs for dead-end service and bi-directional shutoff capability.
Flanged butterfly valves for installation in pipeline systems with flanged connections.
Pipeline strainers that remove debris and particles from fluid flow to protect downstream equipment.
Large-capacity strainers with a basket element that captures debris in pipeline flows.
Devices installed upstream of meters and valves to eliminate turbulence and ensure accurate flow measurement.
One-way valves used at the discharge end of stormwater and sewage outfalls to prevent backflow.
Automatic valves that vent trapped air from pressurized water pipelines to prevent air locks and flow restrictions.
Valves that automatically reduce and maintain downstream pressure in water distribution networks.
Cast iron access boxes installed at grade level to provide access to buried valves and fittings in water networks.
Emergency repair fittings that seal leaks and breaks on existing pipelines without requiring pipe removal.
Fittings that allow hot-tapping into pressurized water mains to create new service connections.
Flexible connectors that absorb thermal expansion, vibration, and misalignment in pipeline systems.
