As a leading manufacturer with a strong commitment to quality and innovation, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our specialized Hard Seal Butterfly Valve, engineered specifically for the demanding environments of offshore platforms and high-temperature fluid control applications. Established in 2016 and backed by ISO9001 certification, we understand the critical need for reliability and durability in offshore operations. Our valve is designed to provide a robust, leak-tight seal under extreme thermal and pressure conditions, ensuring the safety and efficiency of your fluid handling systems. With an annual export value demonstrating our global reach, we deliver solutions trusted by industries from North America to Southeast Asia.
This valve is not just a component; it is a vital safeguard for your high-value assets and personnel. Its core value lies in its exceptional performance where standard soft-seal valves would fail, offering long-term operational stability and significantly reduced maintenance cycles in corrosive and high-heat offshore environments.
Detailed Product Features & Technical Specifications:
- Superior High-Temperature Performance: The hard metal-to-metal seat is engineered to withstand continuous operation at elevated temperatures where elastomeric seals would degrade, ensuring reliable shut-off in processes involving hot oil, steam, or other high-temperature media.
- Robust Construction for Offshore Use: Manufactured from premium materials like carbon steel, stainless steel, or duplex steel, the valve body and components are resistant to saltwater corrosion, atmospheric exposure, and other harsh offshore conditions.
- Bidirectional Sealing Capability: Provides a tight seal against pressure from both flow directions, a critical feature for complex piping systems on platforms where flow direction may vary.
- Low Torque Operation: Advanced disc and stem design minimizes operating torque, which is especially beneficial for larger valve sizes and extends the life of actuators.
- Fire-Safe Design: The metal-seated design inherently offers a degree of fire safety, as it does not rely on combustible polymer seals that can fail in a fire scenario.
- Versatile Actuation Options: Can be fitted with manual hand levers, gear operators, or automated actuators (pneumatic/electric) to suit your specific control and automation requirements.
The table below outlines key technical parameters for our standard range:
| Parameter | Specification |
| Size Range | 2" to 48" (DN50 to DN1200) |

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a hard seal over a soft seal butterfly valve for my application?
A: The primary advantage is superior temperature and abrasion resistance. Hard seal (metal-seated) valves maintain their integrity in high-temperature and abrasive media where soft (elastomer) seals would quickly wear out or melt, making them essential for offshore high-temperature fluid control. -
Q: Can this valve handle cryogenic services as well?
A: While optimized for high temperatures, specific material grades and designs can be configured for low-temperature services. Please consult with our engineering team for custom requirements. -
Q: What types of actuators are compatible with this valve?
A: The valve is designed for versatility. It can be paired with manual gear operators, pneumatic actuators for on/off or modulating control, or electric actuators. The mounting interface is standardized to accommodate major actuator brands. -
Q: How does the valve perform in highly corrosive offshore environments?
A: We offer body and trim materials specifically selected for corrosion resistance, such as 316 stainless steel or duplex stainless steels. These materials provide excellent protection against saltwater spray and other corrosive elements common on offshore platforms. -
Q: What is the typical delivery lead time for standard sizes?
A: Lead times vary based on size, material, and quantity. Standard configurations often have shorter lead times. We recommend contacting our sales team with your specific needs for an accurate delivery schedule. -
Q: Do you provide custom modifications or special coatings?
A: Yes, as a manufacturer, we offer customization options. This can include special trim materials, extended stems, locking devices, and protective coatings like epoxy or galvanizing to meet specific project specifications. -
Q: What maintenance is required for these hard seal valves?
A: They are designed for minimal maintenance. Periodic visual inspection for external corrosion and operational checks of the actuator (if equipped) are recommended. The hard seat typically offers a much longer service life than soft seats, reducing the frequency of internal maintenance.
