Introduction

Three Eccentric Butterfly Valve is a metal hard seal butterfly valve. It is characterized by overlaying high-temperature and corrosion-resistant alloy materials on the sealing surface layer of its valve seat and fixing a multi-layer soft laminated seal ring on the butterfly plate. This process makes the tri eccentric butterfly valve more resistant to high-temperature and high-pressure environments and corrosion than traditional butterfly valve products. The product is widely used in the oil, natural gas, medicine, food, water treatment, and shipping industries.

Features

Because of the unique design of the triple eccentric, the valve of the Three Eccentric Butterfly Valve is very easy to operate, and there is no friction between the butterfly plate and the valve body when opening and closing. At the same time, when the valve is closed, the torque of the transmission mechanism increases to provide a compensation seal, which greatly improves the sealing performance of the valve and extends the service life of the butterfly valve. The application of alloy, stainless steel, composite graphite, and other materials greatly improves the corrosion resistance and wear resistance of the product, and makes it still have good sealing performance even under high-temperature conditions.
