Fire Butterfly Valve
Product Description
Fire PTFE Seat Lug Type Butterfly Valve
Introduction
The Fire PTFE Seat Lug Type Butterfly Valve is a specialized valve designed to handle demanding applications where fire safety and durability are critical. It is commonly used in various industrial and municipal systems for controlling the flow of fluids, including water, chemicals, and gases. This type of valve is distinguished by its fire-resistant capabilities, PTFE (Polytetrafluoroethylene) seat material, and lug type design.
Key Features
1. Fire Safety Certification:
- The valve is certified for fire safety, complying with standards such as API 607, ISO 10497, and EN 559. This certification ensures that the valve can withstand high temperatures and maintain its integrity during a fire, preventing the spread of flames through the pipeline.
2. PTFE Seat Material:
- The seat of the valve is made from PTFE, a high-performance polymer known for its excellent chemical resistance, low friction properties, and high-temperature tolerance. PTFE ensures a reliable, leak-proof seal and enhances the valve’s lifespan under harsh operating conditions
3. Lug Type Design:
- The lug type design features threaded holes in the valve body, allowing the valve to be bolted between two flanges. This design simplifies installation and maintenance, as the valve can be easily removed or replaced without disturbing the pipeline connections.
4. Butterfly Valve Mechanism:
- The valve utilizes a disc-shaped closure element that pivots on a shaft to control the flow of fluid. The butterfly valve mechanism allows for quick, precise adjustments and provides a compact, efficient solution for flow regulation.
5. High Durability:
- Constructed from high-quality materials, the valve is designed to endure harsh conditions, including extreme temperatures, high pressures, and corrosive environments. This durability ensures a long service life and reliable performance.
6. Versatility:
- The Fire PTFE Seat Lug Type Butterfly Valve is suitable for a wide range of applications, including water treatment plants, chemical processing, HVAC systems, and fire protection systems. Its design allows for both on/off and throttling functions.
Technical Specifications
- Size Range: Typically available in sizes from 2 inches to 24 inches (50 mm to 600 mm) or larger, depending on the manufacturer.
- Pressure Rating: Can handle various pressure ratings, often up to ANSI Class 150 or higher, based on the valve’s design and application.
- Temperature Range: Capable of operating in temperatures ranging from -20°C to 200°C (-4°F to 392°F), depending on the PTFE seat and body material specifications.
- End Connections: Lug type connections allow for easy installation with standard flanges and are compatible with ANSI, DIN, and JIS standards.
