TUG High-Performance Double Eccentric Butterfly Valve, ACT130R, ACT80R, ACT40R, ACT200R, ACT300R, ACT500R, ACT850R Pneumatic High-Performance Double Eccentric Butterfly Valve

The TUG high-performance double eccentric butterfly valve features a unique structural design for the disc and seat, ensuring reliable sealing, excellent performance, and a long service life. The standard soft-seat design employs a flexible lip-seal ring structure that compensates for changes in temperature and pressure without the need for additional O-rings or metal gaskets to maintain sealing. Additionally, the valve is available with fire-safe soft seats and hard seats, making it suitable for a wide range of operating conditions.
Performance Characteristics of TUG High-Performance Double Eccentric Butterfly Valve
1. The valve provides bidirectional sealing, achieving bubble-tight leakage performance, making it suitable for bidirectional flow conditions. The sealing ring has a long service life and requires minimal maintenance. The valve is designed with fire-safe features, making it suitable for applications requiring fire protection.
2. The spherical surface of the TUG valve is polished to a mirror-like finish, reducing wear between the disc and seat.
3. The wafer-style connection saves space and reduces costs.
Product Advantages of TUG High-Performance Double Eccentric Butterfly Valve
1. Depending on the user's specific operating conditions, seats made of different materials and reinforced PTFE compositions can be selected to meet temperature requirements ranging from -40°C to +220°C.
2. The unique design of the offset shaft and eccentric disc ensures that the sealing ring does not contact the disc when the valve is open or in an intermediate position, eliminating wear points on the sealing ring. This results in low operating torque and a compact actuation mechanism.
