| Params | Product Name: ISO 5675 Ball Valve Agricultural Quick Couplings Manufacturer: JINGYE Fittings (Ningbo Jingye Fluid Fittings Co., Ltd.) Series: JY-AG-BV; ISO 5675:2021 agricultural hydraulic quick coupling family. Construction: Carbon steel male tips and female sockets with spring-loaded ball-check shutoff, manual sliding-sleeve locking and double isolation. 1. Series Identification and Nominal Sizes JINGYE Series: JY-AG-BV. Published ball-valve coupling sets cover 1/4"–1" NPT/BSP ports. Standard reference body sizes: 1/4" (DN6.3), 3/8" (DN10), 1/2" (DN12.5), 3/4" (DN20) and 1" (DN25). Order male tip, female socket or matching set; body/interface size and rear hydraulic port size are specified independently. 2. ISO 5675 Agricultural Mating Interface Reference: ISO 5675:2021 general-purpose agricultural hydraulic coupling interface. Control plug nose, tip diameter, retaining groove, socket entry and ball-lock alignment. The widely used 1/2" universal tractor tip supports selected Pioneer-style replacement applications. ISO 5675 agricultural geometry is distinct from ISO 5676 trailer-brake interfaces and is not universally interchangeable with ISO 7241-A or B. 3. Spring-Loaded Ball-Check Valve Construction A spherical steel valve element is pressed by a return spring against a precision-machined conical seat in each half. On coupling, the mating elements unseat to permit hydraulic flow; on separation, both ball checks close to retain hydraulic oil. Ball-to-seat sealing and valve travel determine leakage. This ball-check construction is not a hand-operated quarter-turn pipeline ball valve or a conical poppet design. 4. Sliding Sleeve and Ball-Locking Operation A manually retracted female sleeve allows the male agricultural tip to enter; hardened radial locking balls engage its groove when the sleeve returns. Control ball retention, sleeve travel, return-spring force, plug profile and full insertion. Standard manual-sleeve coupling is separate from push-pull, bracketed breakaway or specialized connect-under-pressure versions. Relieve pressure before coupling and uncoupling. 5. Working Pressure and Burst Strength JINGYE published ball-valve size references: 1/4" 345 bar (5,000 psi); 3/8" 276 bar (4,000 psi); 1/2", 3/4" and 1" 207 bar (3,000 psi). Comparable EH-68 ball-type designs instead publish 207 bar for 1/4"–1/2", 170 bar for 3/4" and 150 bar for 1", with corresponding minimum burst levels 828/680/600 bar. These are separate series, not combined JY-AG-BV ratings. 6. Rated Flow and Hydraulic Pressure Drop Published JINGYE ball-valve references by body size: 1/4" 3 US gpm (11.4 L/min); 3/8" 6 gpm (22.7 L/min); 1/2" 12 gpm (45.4 L/min); 3/4" 28 gpm (106 L/min); 1" 50 gpm (189.3 L/min). Pressure loss depends on spherical valve lift, passage size, oil viscosity, temperature and connected pair. Distinguish rated flow from maximum flow and evaluate the whole hose circuit. 7. Materials, Seals and Surface Finish Precision CNC-machined carbon steel bodies, sleeves and plugs combine with hardened ball-check valve elements, machined seats, locking balls and steel return springs. NBR (Buna-N) seals suit compatible mineral hydraulic oils; FKM or selected EPDM alternatives depend on fluid and temperature. Carbon steel surface protection: trivalent chromium zinc plating, typically 8–12 μm, with enhanced zinc-nickel options. Selected international references use metal-to-metal ball-seat contact. 8. Ports and Dimensional Reference Hydraulic port options: BSPP (G), NPT/NPTF, selected BSPT and SAE ORB as specified. JINGYE ball-valve female socket reference length/OD by 1/4"–1": 53.5/27.6, 63.0/34.0, 66.3/38.6, 82.5/48.2 and 96.5/56.0 mm. Corresponding male tip lengths: 36.0, 40.0, 43.5, 53.5 and 63.0 mm. Connected lengths: 72.2, 82.6, 87.8, 107.8 and 126.8 mm. Dimensions depend on chosen port and series. 9. Inspection, Qualification and Service Conditions Quality Management: ISO 9001:2015. Inspect ISO mating profile, ball-check seats, spherical valve hardness, sleeve/groove engagement, port gauges, springs, seal installation, coating thickness and cleanliness. Agreed verification includes male/female interchange, coupled and uncoupled leakage, rated-flow pressure drop, proof/burst pressure, impulse endurance and repeated connection cycles. NBR service temperature reference: -20°C to +100°C, depending on compound. 10. Agricultural Applications and OEM Procurement Applications: tractor rear remote outlets, farm implements, balers, planters, sprayers, loaders, harvesters, agricultural hose assemblies and rural machinery maintenance. Supply choices: male ball-valve tips, female couplers, matching pairs, BSP/NPT/SAE ports, seals, caps, product marking and private-label packaging. JINGYE Fittings supports dimensional matching, samples, mixed-SKU orders, OEM manufacturing, replacement procurement and second-source supply. | Material | Body Materials: Precision CNC-machined carbon steel (C20/C45 options by component) for ISO 5675 agricultural male tips, female sockets and sliding sleeves.
