Description
DKV D373H high-performance butterfly valve is a high-performance butterfly valve developed to solve the problem that ordinary valves are difficult to adapt to high temperature, low temperature, high pressure, vacuum and other working conditions. It has a unique self-sealing and double eccentric structure. Through the choice of three sealing materials, high performance is ensured under a wide range of use conditions. It can be applied to ball valves, gas valves and other working conditions that cannot be closed due to corrosion and high-temperature steam, and has a wide range of fluids.
