Marine Globe Valve - Definition & FunctionA marine globe valve is a linear-motion valve designed for precise flow regulation in shipboard piping systems. Unlike simple on/off valves (e.g., gate valves), it allows fine-tuned throttling of liquids/gases (e.g., seawater, fuel, steam) while maintaining reliable shutoff.Key Features of Marine Globe Valves1. Design & Working PrincipleSpherical body with an internal baffle (partition) forcing flow to change direction, increasing resistance for better control.Movable disc/plug presses against a stationary seat to regulate flow (screwed via a handwheel or actuator).Stem operation: Raises/lowers the disc linearly (unlike rotary ball/gate valves).2. Why Ships Use Globe ValvesAccurate flow adjustment: Critical for cooling systems, fuel dosing, or steam lines.Positive sealing: Prevents leaks when fully closed (e.g., high-pressure steam isolation).Corrosion-resistant materials: Bronze, stainless steel, or duplex alloys for seawater/chemical resistance.3. Common Marine ApplicationsEngine cooling water controlFuel oil supply regulationSteam system throttling (e.g., boiler feed lines)Hydraulic system pressure managementGlobe Valve vs. Other Marine ValvesValve TypePrimary FunctionBest for Marine Use When...Globe ValveThrottling/flow controlPrecise adjustment needed (e.g., cooling systems)Gate ValveFull on/off (low resistance)Main seawater intake (minimal pressure drop)Ball ValveQuick on/off operationFuel tank isolation (fast shutoff)Check ValvePrevent backflowBilge pumps, overboard dischargesPros & Cons in Marine Environments Pros:Excellent for frequent flow adjustments.Tight shutoff (less leakage than gate valves).Repairable without removing from pipeline.Cons:Higher pressure drop than gate/ball valves (not ideal for high-flow, low-resistance systems).Heavier and bulkier than ball valves.Need help selecting a globe valve for a specific ship system? Ask me about materials, pressure ratings, or installation tips! JIS F7307 is a Japanese Industrial Standard (JIS) specification for marine cast iron globe valves, specifically those rated for 10K (10 kilograms-force per square centimeter, or approximately 1 MPa) pressure. These valves are commonly used in various marine applications for controlling the flow of fluids like water, oil, and steam. Key features of JIS F7307 valves include:Material: Cast iron (FC-200 is a common material grade). Pressure Rating: 10K (10 kgf/cm2, or approximately 1 MPa). Type: Globe valves, including straight and angle types, with and without screw-down non-return (SDNR) functionality. Connection: Flanged (FF, or flat face) connections are common. Applications: Typically used for controlling the flow of fluids like water, oil, and steam in marine environments. Standards: Referenced alongside other JIS standards like F7305 and F7309. Size Range: Available in various sizes, typically from DN15 to DN300. The standard also specifies details regarding valve design, materials, testing procedures (including hydrostatic testing), and dimensions. For example, one document specifies the test pressure for the body (2.1 MPa for sizes up to 200mm and 1.5 MPa for larger sizes). Similarly, the seat test pressure is 1.5 MPa for sizes up to 200mm and 1.1 MPa for larger sizes. 1.JIS F7307 MARINE CAST IRON 5K 10K 16K Globe VALVES:10K50/65/80/100/125/150/200/250/3002.Standard:JIS F7305,F7307,F73093.Pressure:5K,10K,16K4.Size:DN15-DN3005.Material:cast iron,cast steel,forged steel,brass,bronze6.Type:globe valve,angle valve,SDNR globe valve,SDNR angle globe valve7.Media: Water,Oil,SteamSIZE TABLE(7307)DNdLDCNO.htHD2505022015512041920285160656527017514041922310200808030018515081922320200100100350210175819243702501251254202502108232442028015015049028024082326470315200200570330290122326555355250250740400355122530680450300300840445400162532770500MAME OF PARTMATERIALS TABLE CLASS BCLASS ABODYFC200BONNETFC200DISCBC6SUS420VALVE SEAT BC6SUS420STEMC3771BD OR BE SUS420GLAND PACKING BC6GASKETNON-ASBESTOSHANDWHEELFC200Company Qingdao Hongfeng Xianglong Valve Manufacturing Co., Ltd. is a professional marine valve manufacturing enterprise located in Mingcun Town, Pingdu City, Qingdao, China.
