As an experienced manufacturer with ISO9001 certification since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd proudly presents the JIS F7312 Globe Valve for Oil. Designed specifically for demanding oil media applications, this valve combines a sturdy carbon steel body, a durable 304 stainless steel stem, and a reliable PTFE seat to deliver exceptional sealing performance and long service life. With pressure ratings of 150LB and 300LB, and a size range from DN15 to DN250, it offers flexible solutions for various piping systems in the oil industry.
Our globe valve is manufactured strictly according to JIS F7312 standard, ensuring compatibility with Japanese industrial piping systems and high dimensional accuracy. Whether you need to control the flow of crude oil, lubricating oil, or other petroleum-based fluids, this valve provides precise throttling and positive shut-off. The carbon steel body offers robust mechanical strength to withstand high pressures, while the 304SS stem resists corrosion and galling. The PTFE seat ensures a tight seal even in harsh conditions, reducing leakage and maintenance costs.
Product Features & Benefits
- High-Quality Materials: Carbon steel body (ASTM A216 WCB or equivalent) provides excellent strength and durability for oil service. 304 stainless steel stem offers superior corrosion resistance and wear life. PTFE seat ensures low friction and leak-tight sealing.
- Versatile Pressure & Size Options: Available in 150LB and 300LB pressure classes, covering nominal diameters from DN15 to DN250, suitable for a wide range of flow rates and system pressures.
- JIS Compliance: Manufactured under JIS F7312 standard, this valve guarantees interchangeability and reliable performance in JIS-based piping systems.
- Precise Flow Control: The globe valve design allows for linear flow characteristics, ideal for throttling and regulating oil media flow with high accuracy.
- Leak-Proof Design: The combination of PTFE seat and 304SS disc ensures bubble-tight shut-off, meeting stringent leakage requirements.
- Easy Maintenance: The bolted bonnet design allows for quick internal inspection and seat/parts replacement without removing the valve from the pipeline.
- Wide Application: Apart from oil media, this valve can also handle water, gas, and other non-aggressive fluids (please confirm compatibility with our sales team).

Frequently Asked Questions (FAQ)
-
Q: Can this valve be used for high-viscosity oil?
A: Yes, the PTFE seat and full bore design provide smooth flow for high-viscosity media. However, for extremely thick oils, we recommend consulting our engineers for specific viscosity limits. -
Q: What is the standard connection? Are other flange standards available?
A: The standard connection is JIS 10K/20K flanged. We can also customize to ANSI, DIN, or other flange standards upon request. -
Q: What is the maximum working temperature for PTFE seat?
A: PTFE seat is suitable up to 200°C. For higher temperature requirements, alternative seat materials like PEEK or metal-seated options are available. -
Q: Is this valve suitable for steam service?
A: No, this valve is primarily designed for oil media. For steam, we recommend a different seat material. Please contact us for steam-rated valves. -
Q: What pressure tests do you perform?
A: Each valve undergoes hydrostatic shell test at 1.5 times the rated pressure, and a seat leakage test at 1.1 times rated pressure per JIS B2003. -
Q: Can I get a pneumatic or electric actuator installed?
A: Yes, we can provide actuated versions with suitable pneumatic or electric actuators. Please specify mounting requirements. -
Q: What is the typical lead time?
A: For standard sizes and pressure ratings, lead time is 15–25 working days. Custom orders may require 30–45 days. -
Q: Do you offer warranty?
A: Yes, we provide a standard 12-month warranty against manufacturing defects from the date of shipment.
