Gate Valve Bronze JIS 5K - F7367

Bronze Gate Valve JIS 5K F7367

Flanged bronze gate valve for low-pressure marine piping systems, designed in accordance with JIS F 7367-1996. Intended for line isolation with handwheel operation and rising stem. Not suitable for throttling or intermediate position service.

Technical Specifications

• Nominal Pressure: JIS 5K
• Test Standard: JIS F 7400-1996
• Body Hydrostatic Test: 1.05 MPa
• Seat Test: 0.7 MPa
• Sizes: DN15 to DN40
• Connection: Flanged
• Operation: Handwheel FC200
• Gasket: Non-asbestos

Construction Materials

Body, bonnet, and wedge are BC6 bronze. Stem is C3771BD or BE. Bronze alloys provide compatibility with seawater and freshwater, suitable for marine environments.

Typical Applications

• Seawater cooling lines
• Shipboard freshwater systems
• Auxiliary engine room systems
• Isolation on pumps and manifolds
• Marine installations with JIS 5K flanges

Selection Criteria

Gate valves are selected for low flow resistance in fully open position and positive shut-off. For frequent throttling or flow control, globe or control valves are recommended.

Maintenance and Leakage

Maintenance includes inspection of seat, bonnet gasket, and stem area. Seat test at 0.7 MPa should be verified during commissioning or replacement in marine piping.

FAQ

Is it suitable for flow regulation?
No. Gate valves are primarily for full open or full close service.

Which standard covers the design?
Design is per JIS F 7367-1996.

Are actuator options available?
This version is handwheel operated. For automation, verify stem, torque, and installation space compatibility separately.
