DDT373H Clamp type elastic metal hard seal butterfly valve

Dt643H Pneumatic hard seal butterfly valve - Product Description
Dt643H pneumatic hard seal butterfly valve is a three-eccentric hard seal butterfly valve series products, belongs to the long life, energy saving butterfly valve. The products conform to the national standard JB/T8527-97(metal seal butterfly valve), GB/T13927-92(general valve pressure test) standard and other related standards of the valve. This product is composed of valve body, butterfly plate, sealing ring, transmission mechanism and other main components. Its structure adopts the three-dimensional eccentric principle design, elastic seal and hard and soft multi-layer seal compatible with the new processing technology, so that the butterfly valve in the operation of the work, reduce its torque force, to achieve labor saving, energy saving function. So as to ensure the overall corrosion resistance. High temperature resistance. Reliability against breakage.
