Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, presents the JIS F7312 16K Cast Steel Globe Valve with Stellite Seats – a robust solution designed for demanding industrial flow control. Manufactured under strict ISO9001 quality management, this valve combines Japanese industrial standard JIS F7312 with European pressure vessel design code BS EN 12516, ensuring global compatibility and reliable performance. With an annual export value of US$1–1.5 million, we serve markets across North America, South America, Europe, Asia, Africa, and Oceania, delivering valves that meet the highest engineering expectations.
The 150mm nominal diameter globe valve features a durable cast steel body, Stellite alloy seats for superior wear and corrosion resistance, and a 16K pressure rating suitable for high-pressure steam, water, oil, and gas applications. Its straight pattern design minimizes flow resistance while providing excellent throttling and shut-off capabilities. Every valve is fully compliant with BS EN 12516 for wall thickness and pressure design, ensuring safety and longevity in critical systems.
Key features and benefits include:
- Durable Construction: Cast steel body withstands high pressure and temperature, ideal for power plants, refineries, and chemical industries.
- Stellite Seats: Heat- and wear-resistant cobalt‑based alloy guarantees tight shut-off, even after repeated cycles.
- JIS F7312 Compliance: Conforms to Japanese industrial standard for interchangeability and reliability.
- BS EN 12516 Design: European pressure vessel design ensures consistent wall thickness and safety margin.
- Flanged Connection: Easy installation and maintenance; compatible with JIS B2220 flanges.
- Manual Handwheel Operation: Precise control with rising stem and position indicator.
- Wide Applicability: Suitable for water, steam, oil, and non-corrosive gases up to 425°C.

Frequently Asked Questions
Q1: What is the difference between 16K and other pressure ratings like 150LB?
A1: 16K is a Japanese pressure rating equivalent to approximately PN2.0 MPa (290 psi). It is similar to Class 150 in ANSI but with slight dimensional differences. Our valve is designed per JIS F7312, which specifies pressure-temperature ratings.
Q2: Can this valve be used for steam service?
A2: Yes, it is suitable for saturated and superheated steam up to 425°C, depending on the pressure. The Stellite seats provide excellent erosion resistance in steam applications.
Q3: What flange standard does it match?
A3: The valve comes with flanges matching JIS B2220 (10K/16K). If you need other standards (e.g., ANSI, DIN, BS), please inquire – we offer customization.
Q4: Is the valve bidirectional?
A4: Globe valves are typically unidirectional, meaning they should be installed with flow direction as indicated (usually flow below the disc). This design ensures proper sealing and minimal wear.
Q5: What is the expected service life of Stellite seats?
A5: Stellite is a cobalt-based alloy with high hardness and wear resistance. Under normal operating conditions (clean fluids, moderate cycling), seats can last many years. Actual life depends on media, temperature, and frequency of operation.
Q6: Do you provide a test certificate?
A6: Yes, each valve undergoes hydrostatic and shell testing. We can provide a Material Test Certificate (MTC) and a Pressure Test Certificate upon request.
Q7: Can I get a sample before bulk order?
A7: Absolutely. We accept sample orders for evaluation, with lead time typically 2–3 weeks.
Q8: What is the minimum order quantity (MOQ)?
A8: For standard sizes, MOQ is 1 piece. For customized specifications, MOQ may vary; please contact our sales team.
