High performance double eccentric butterfly valve:

The HS40 series high-performance double eccentric butterfly valve designed by Fujian Bolei Company has a special floating seat design, which automatically adjusts the seat position according to the direction of the pressure source, achieving the effect of double-sided pressure holding of the valve and increasing the service life of the valve seat. In accordance with the requirements and experiments of the air separation market, the service life can reach over 500000 times. The valve shaft is specially designed to prevent fluid from entering the valve shaft and causing the valve shaft to become stuck, The model of butterfly valve can be stainless steel or other special alloy steel for use by the owner according to different working conditions. The valve seat is provided with PTFE, RTFE, PEEK, METAL, and other materials, which is suitable for most situations with different temperatures and pressures such as petrochemical, oil refining, air separation, and CDA.

The main characteristics of high-performance double eccentric butterfly valves are:

1. The valve shaft is specially designed for dust prevention

2. The entire series is equipped with a structure of electrostatic conductivity device

3. Patent for pressure ring structure

4. Selection of soft and metal valve seats

5. Provide jacket design for fluid crystallization caused by temperature changes.

6. Standard materials A216 WCB, A351 CF8, A351 CF8M. For other special materials, please consult our company separately

7. Bidirectional pressure holding design
