Product Description Product DescriptionI. Product Positioning and Core FunctionsThe JIS cast iron straight-through globe valve is a manual shut-off valve compliant with Japanese Industrial Standards (JIS). It uses a handwheel to drive the stem upward/downward, bringing the disc into tight contact with the seat to shut off or throttle media (liquid/gas). With a straight-through flow path + metal-to-metal seal, it suits medium-low pressure, low-corrosion applications, widely used in marine pipelines and industrial auxiliary systems. Core values: reliable sealing + JIS compliance.II. Core Structure and Design Details1. Main StructureFlow Path: Straight-through (media flows along the seat centerline, with less turbulence but higher resistance than gate valves). Discs are flat or conical, forming line/face contact with the metal seat for reliable sealing.Actuation System: Handwheel (cast iron/phenolic plastic) drives the stem (T-thread) via screw transmission. The stem connects rigidly (or hingedly) to the disc, requiring multiple rotations to open/close (e.g., DN50 needs ~10-15 turns).Sealing Pair: Metal-to-metal sealing (cast iron/bronze) between disc and seat. Some models add soft seals (e.g., PTFE) for mild corrosion. Complies with JIS F7307 leakage standards (bubble test, no visible leakage at low pressure).2. Connection and InstallationConnection: Flanged (mainstream), with dimensions per JIS B2220. Two types:Marine (JIS F7307): Flanges with locating bosses (for ship pipelines).Industrial (JIS F7309): Flat-weld flanges (for general industrial use).Flow Direction: Unidirectional-install per the arrow ("low inlet, high outlet") to use media pressure for sealing (reverse installation causes leakage).III.

Standards and CertificationsManufacturing Standards:Marine: JIS F7307 (Marine Cast Iron Globe Valves) (flanges with bosses).Industrial: JIS F7309 (General-Purpose Cast Iron Globe Valves) (flat flanges).Pressure Tests: Per JIS B2003-Shell test: 1.5×PN; Seat test: 1.1×PN.VI. Application Scenarios and AdvantagesCore ApplicationsMarine Systems: Main engine fuel supply (shut-off fuel), fresh water cooling (control flow), bilge/ballast lines (manual on/off).Industrial Auxiliaries: Low-pressure steam (≤100oC, e.g., heating), machine tool lube lines, small boiler feedwater (shut-off water).AdvantagesReliable Sealing: Metal-to-metal sealing ensures tight shut-off in medium-low pressure (e.g., fuel leak prevention).JIS Compatibility: Dimensions/pressure ratings match JIS, compatible with Japanese/Southeast Asian equipment (e.g., Mitsubishi, Kawasaki).Easy Maintenance: Simple disassembly; replace discs/seats individually (no need to replace the entire valve).VII. Limitations and PrecautionsLimitations High Flow Resistance: Local resistance coefficient is 5-10× higher than butterfly valves-unsuitable for high-flow, energy-sensitive lines.Material Constraints: Cast iron resists neither strong corrosion (acids/alkalis) nor high temps (>150oC)-prone to body rust or seal failure.Slow Operation: Requires multiple rotations to open/close-unsuitable for emergency quick shut-off. Precautions Flow Direction: Strictly install per the "low inlet, high outlet" arrow-reverse installation causes insufficient sealing pressure and leakage.Media Cleanliness: Install filters for particle-containing media to avoid seat scratching (metal seats leak rapidly if damaged).Long-Term Storage: Loosen the stem by rotating the handwheel before operation (prevents rust jamming), then actuate slowly.
