Whether you need to regulate water, oil, or gas in industrial piping systems, our angle valve offers exceptional flow characteristics and long service life, backed by our ISO9001 certified manufacturing process and over 8 years of export experience to global markets.
The following detailed information will help you understand the features, technical specifications, and advantages of this product, along with the trust you can place in Shanghai Zhibang as your partner.
Product Features & Benefits
- Ductile Iron Body: Provides higher strength and impact resistance compared to gray iron, reducing the risk of cracking under pressure or temperature variations.
- Epoxy Coating (Standard): Applied internally and externally to prevent corrosion, extend service life, and meet hygiene requirements for water applications. Coating thickness typically 250–350 microns.
- JIS F7306 Compliant Design: Ensures interchangeability and compatibility with existing JIS piping systems, including face-to-face dimensions, flange drilling pattern, and stem design.
- 5K Pressure Class (0.5 MPa ~ 0.7 MPa): Suitable for low to medium pressure systems, commonly used in shipbuilding, water treatment, and industrial utilities.
- DN80 (3-inch) Flanged Connections: Easy to install and maintain, with reliable sealing using gaskets per JIS B2220.
- Handwheel Operation: Ergonomically designed handwheel for smooth open/close actions, with optional locking device for safety.
- Versatile Application: Compatible with water, seawater, air, steam (with appropriate seals), and many non-aggressive fluids.
- Optional Seat Materials: Available in stainless steel, bronze, or PTFE-lined for corrosive media.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a JIS F7306 angle valve and a standard globe valve?
A: The angle valve has a 90-degree flow path, which reduces pressure loss and allows installation in confined spaces. It is often used in place of a globe valve with an elbow fitting. -
Q: Can this valve be used for steam?
A: Yes, with appropriate seal material (e.g., EPDM or Viton) and within the temperature limits. For steam above 120°C, we recommend a metal-seated option. -
Q: Is the epoxy coating food-grade?
A: Standard epoxy is industrial grade. Food-grade (FDA compliant) coating is available as an option upon request. -
Q: What flange standard does this valve match?
A: It matches JIS B2220 5K flange dimensions. It can also be adapted to ANSI or DIN flanges with custom machining (contact us for details). -
Q: How do I operate the handwheel if the valve is installed in high position?
A: A chain-wheel attachment or a gearbox can be provided for remote operation. Please specify when ordering. -
Q: What is the lead time for a DN80 angle valve?
A: Usually 7-15 days for standard models. Larger quantities or custom specifications may require 20-30 days. -
Q: Does the valve come with test certificates?
A: Yes, each valve is hydrostatically tested and a test certificate is included. Material certificates are available upon request. -
Q: Can you supply with a locking device?
A: Yes, a padlock handle or locking bracket is available as an option to prevent unauthorized operation.
