Shanghai Zhibang Valve Manufacture Co., Ltd. presents our premium JIS F7312 Forged Steel Globe Valve – a robust solution designed for demanding marine and high-pressure industrial applications. Since 2016, we have been dedicated to delivering valves that combine precision engineering with reliable performance. This globe valve, available in sizes DN15 to DN50 with 16K/20K pressure ratings, offers both threaded and flanged end connections for versatile installation. Its forged steel construction ensures exceptional strength and corrosion resistance, making it a trusted choice for shipbuilders, offshore platforms, and high-pressure fluid systems worldwide.
Key Features & Technical Specifications
- Material Excellence: Manufactured from high-quality forged steel (A105 or equivalent), ensuring durability under extreme pressure and temperature conditions.
- Standards Compliance: Designed and tested per JIS F7312 (Japanese Industrial Standards for marine valves), guaranteeing compatibility with international maritime requirements.
- Pressure & Size Range: Rated for 16K and 20K (approx. 1.6 MPa to 2.0 MPa), with nominal diameters from DN15 (1/2”) to DN50 (2”).
- Dual Connection Options: Available with threaded ends (BSP, NPT, or JIS threads) and flanged ends (FF, RF, or RTJ facing), allowing seamless integration into existing piping networks.
- Flow Control Performance: The globe valve design provides precise throttling and positive shut-off, with a linear flow characteristic ideal for regulation and isolation.
- Marine-Grade Protection: Surface treatment options include anti-corrosion coating (e.g., epoxy or zinc plating) to resist saline environments.
- Easy Operation: Manual handwheel with rising stem indicator – suitable for both on/off and modulating service. Actuator mounting pad available upon request.

Frequently Asked Questions (FAQ)
-
Q: What is the main difference between 16K and 20K pressure rating?
A: 16K corresponds to 1.6 MPa, while 20K corresponds to 2.0 MPa. Both are suitable for high-pressure marine systems; choose based on your system's maximum operating pressure. -
Q: Can this valve be used for steam service?
A: Yes, the forged steel globe valve is suitable for steam, water, oil, and gas within the specified pressure and temperature limits. For high-temperature steam, we recommend Stellite trim. -
Q: Are threaded and flanged connections available on the same valve?
A: No, each valve comes with either threaded ends or flanged ends. However, we can supply both types for mixed connection requirements in the same order. -
Q: What thread standards are available?
A: Standard threads are BSP (JIS) or NPT. Please specify your preferred thread type when ordering. -
Q: Do you provide actuators or gearboxes?
A: Yes, we offer optional pneumatic, electric, or hydraulic actuators, as well as gear-operated units. Please inquire for details. -
Q: What is the typical lead time?
A: For standard sizes DN15-DN50 with common materials, lead time is 7–15 working days. Custom orders may require 20–30 working days. -
Q: How do you ensure quality?
A: Each valve is tested according to JIS B2003 and ISO 5208. We perform 100% hydrostatic testing, and random seat leakage tests. ISO9001 certified. -
Q: Can I get a sample before bulk order?
A: Yes, sample orders are accepted. We can arrange a sample with your logo for qualification.
