Storm Valve Angle Cast Steel JIS 10K - F3060

JIS 10K F3060 Cast Steel Angle Storm Valve

The F3060 JIS 10K is a flanged angle storm valve constructed from cast steel, designed for marine discharge lines terminating at the ship side. This product is specified as an angle flow valve, with flanged connections and a nominal pressure rating of 10K.

Standards and Construction

• Type: JIS F3060 angle storm valve
• Flanges: JIS B2220 – 10K
• Inspection / Construction: JIS F7400
• Typical DN: 50 to 200
• Body: cast steel SC49
• Seat: NBR
• Disc: bronze BC6
• Shaft: stainless steel SUS403

Angle Pattern Arrangement

The angle pattern changes flow direction by 90°, used where the discharge line must connect directly to the ship’s side outlet. Compared to the straight F3059 type, it eliminates the need for a separate elbow but requires precise flange alignment and minimization of piping-induced mechanical loads.

Operation

The valve permits discharge from the system and restricts seawater ingress under external backpressure (wave or water level). The F3060 variant is angle type with manual closing device for mechanical isolation during operation or inspection.

Typical Applications

• Sanitary discharge lines
• Scupper and drain lines
• Grey water discharge
• Overboard discharge piping
• Bilge discharge (if specified)

Selection and Maintenance Considerations

Selection should confirm DN, flange class JIS 10K, flow direction, installation position, closing device type, and NBR compatibility with the process medium. Maintenance includes seat cleanliness, free disc movement, NBR wear, and cast steel body corrosion inspection.
