From Shanghai Zhibang Valve Manufacture Co., Ltd. — a professional manufacturer established in 2016 with annual export value of US$1–1.5 million — we proudly present the JIS F7312 Marine Globe Valve in sizes DN25 to DN300, with pressure ratings of 10K and 16K. This valve features a durable cast steel body and flanged ends, and is certified by both CCS (China Classification Society) and BV (Bureau Veritas), ensuring reliable performance for demanding marine applications. Designed for fluid control in shipboard piping systems, it combines robust construction with precise throttling capability, making it an essential component for ballast, cooling, and fuel oil systems.
Our JIS F7312 globe valve is manufactured under strict ISO9001 quality management, guaranteeing consistent dimensional accuracy and pressure integrity. The cast steel body offers excellent resistance to seawater corrosion and mechanical stress, while the flanged ends simplify installation and maintenance. With availability across a wide size range and two common pressure classes, this valve meets the diverse needs of shipbuilders, offshore platforms, and port facilities.
Key Features & Technical Specifications
- Material: Cast Steel (WCB or equivalent) – high strength and corrosion resistance.
- Pressure Ratings: 10K (1.0 MPa) and 16K (1.6 MPa) – suitable for various marine system pressures.
- Size Range: DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300 – full coverage for main pipelines.

FAQ – Frequently Asked Questions
-
Q: What is the difference between 10K and 16K pressure ratings?
A: 10K corresponds to 1.0 MPa (approx. 145 psi), while 16K corresponds to 1.6 MPa (approx. 232 psi). Choose based on your system design pressure. Both are common in marine applications. -
Q: Are these valves suitable for seawater?
A: Yes, the cast steel body with optional stainless steel overlay is designed for marine environments. However, for longer life in high-chloride conditions, we recommend consulting our technical team for material upgrades like duplex stainless steel. -
Q: What size range is available?
A: We offer DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, and DN300. Custom intermediate sizes may be available on request. -
Q: Do you provide CCS and BV certificates with each order?
A: Yes, we provide traceable certificates from CCS and BV for each valve. Additional certification from other societies (e.g., DNV, ABS) can be arranged at extra cost. -
Q: What is the typical delivery time?
A: For standard sizes (DN25–DN150) and 10K/16K, delivery is usually 15–30 days after order confirmation. Larger sizes or special requirements may take 30–45 days. Please check with our sales. -
Q: Can the handwheel be replaced with an actuator?
A: Yes, the top flange can be adapted for electric, pneumatic, or hydraulic actuators. Please provide actuator specification for a quotation. -
Q: Is the valve tested before shipment?
A: Absolutely. Each valve undergoes hydrostatic shell test (1.5x rated pressure) and seat leakage test (1.1x rated pressure) per JIS standard. Test reports are available. -
Q: What payment terms do you accept?
A: We accept T/T, L/C, and other negotiable terms. Minimum order quantity is 1 piece for sample testing, and bulk orders enjoy volume discounts.
