Key Features and Technical Specifications
- Robust Cast Steel Construction – The valve body and bonnet are made of high-grade cast steel (WCB grade), providing excellent strength and resistance to thermal stress, corrosion, and erosion in steam service.
- JIS F7312 Standard Design – Conforms to Japanese Industrial Standards (JIS) for marine globe valves, ensuring interchangeability and compatibility with existing JIS piping systems.
- DN50 (2-inch) Size with 10K Pressure Rating – Suitable for medium-pressure steam systems up to approximately 1.0 MPa (145 psi). The 10K rating offers a balance between safety and cost-effectiveness.
- Flanged End Connections – Equipped with flanges per JIS B2220, allowing easy installation and maintenance. Flange facing and drilling patterns are standardized for marine applications.
- LR (Lloyd's Register) Type Approval – This valve has been independently tested and certified by Lloyd's Register, a globally recognized marine classification society, ensuring compliance with stringent safety and quality requirements for shipboard use.
- Steam-Optimized Trim Design – The disc and seat are designed for throttling and shut-off of steam, with materials and geometry that minimize wire drawing and erosion under high-temperature and high-pressure conditions.
- Flexible Applications – While primarily intended for steam, the valve can also handle hot water, compressed air, and non-aggressive gases. Optional seat materials (e.g., Stellite) are available for more severe conditions.
- Compliance with ISO9001 Quality Management – Manufactured under a certified quality system, with traceability of materials and dimensional inspections at every stage.

Why Choose This Globe Valve?
- Marine-Grade Reliability – LR approval means the valve has passed rigorous testing for shipboard use, including fire test, hydrostatic test, and leakage test. It meets the requirements of major shipbuilders and offshore operators.
- Superior Flow Control – The globe valve design provides precise throttling capability, making it ideal for regulating steam flow in heating systems, auxiliary boilers, and steam trace applications.
- Durable Construction – Cast steel body with reinforced walls ensures resistance to water hammer and thermal shock. The flanged ends provide a leak-proof joint even after repeated cycling.
- Low Maintenance – Renewable seat and disc design allow for easy replacement of trim components without removing the valve from the pipeline. Bonnet gasket can be replaced with standard off-the-shelf parts.
- Global Compatibility – Compliant with JIS F7312, widely accepted in Asian and international maritime fleets. Flange dimensions match both JIS and ISO standards.

Frequently Asked Questions (FAQ)
-
Q: What does “10K” mean for this valve?
A: “10K” is a Japanese pressure rating equivalent to approximately 1.0 MPa (145 psi) at ambient temperature. For steam service, the allowable pressure may decrease with temperature; please refer to the pressure-temperature chart available upon request. -
Q: Can this valve be used for superheated steam?
A: Yes, with proper material selection. The standard trim can handle saturated steam. For superheated steam above 300°C, we recommend upgrading the seat/disc material (e.g., Stellite). Please consult our engineers. -
Q: Is the LR approval valid for all classification societies?
A: LR approval specifically satisfies Lloyd's Register requirements. It may also be accepted by other societies (e.g., DNV, ABS) after review. We can provide additional certifications upon request. -
Q: What is the standard delivery time?
A: For DN50 10K globe valves in standard material, lead time is typically 15-30 working days after order confirmation. Urgent orders can be expedited. -
Q: Does the valve come with mounting brackets for an actuator?
A: The standard valve is handwheel-operated. For automation, we offer an optional ISO 5211 mounting pad and can supply pneumatic or electric actuators. -
Q: Are spare parts available?
A: Yes, we supply spare trim sets (disc, seat, stem, and packing) for field maintenance. Please provide the valve serial number for exact matching. -
Q: How should I store the valve before installation?
A: Keep indoors in a dry environment, with end covers in place. Avoid direct exposure to rain or corrosive atmosphere. For long-term storage, apply anti-rust oil on exposed metal surfaces. -
Q: What is the warranty period?
A: We offer a standard 12-month warranty from the date of shipment, covering defects in material and workmanship. Extended warranty options are available.
