Components:
The valve is composed of ductile iron body, stainless steel spindle, stainless steel body seat, ductile iron butterfly plate, ductile iron bottom cover, rubber sealing seat that meets WRAS certification and other valve parts. For surface protection, we will epoxy spray or paint the internal and external surfaces.
Working Principle:
The working principle of the double eccentric butterfly valve relies heavily on its eccentric design. In operation, the valve flap rotates through the stem, at first the flap does not contact the valve seat, as it rotates, the valve flap gradually opens or closes.
Certification:
EN593 is a European standard for metal valves that specifies technical requirements and test methods for butterfly valves for a wide range of fluids, including water, steam, gases and oils. It represents that the valves have reached an internationally recognized level in terms of quality, performance and safety. We can also cooperate with customers to carry out a variety of industrial grade product certification, if you have the need, you can contact us.
Advantages:
Double eccentric design:
The axis of rotation of the valve flap and stem is off the center of the valve seat, forming two eccentrics, reducing friction and prolonging service life.
Good sealing performance:
Due to the reduction of the contact between the valve flap and the sealing surface, the fluid can maintain good sealing under high pressure.
Low torque:
The double eccentric design makes the torque for opening and closing substantially reduced, making operation easier.
Short stroke:
The valve flap requires less rotation angle for opening and closing, and the response speed is fast, which is suitable for the requirement of fast switching.
Easy to install and maintain: Simple structure, easy to maintain.
Wide applicability:
Suitable for a wide range of fluids, including gases, liquids, slurries, etc., and suitable for high temperature and high pressure occasions.
