Suitable for the condition
Petrochemical, chemical industry, electric power, metallurgy, etc
Working temperature changes frequently
Open and close frequently under high temperature, high pressure, and the opening and closing time is short, sealing pressure level can reach PN160, opening general pressure of PN1, operating temperature up to 600 ℃
Shut off the cleaning and dusty air and gas medium
Open the valve of the last stage of the initial stage and close the valve, the valve plate movement parallel to the valve seat, valve plate and valve seat to no friction between moving
Main connecting rod with articulated connecting rod almost isometric, under the condition of high temperature, linkage will not be stuck
Drive shaft near the centerline of the valve open and close the valve only need a small torque
Special link mechanism provided by the pressure in the center of the valve, sealing surface force uniform, good sealing
Choose materials according to different working conditions
Choose the coating according to different working conditions
Actuators in the form of electric, hydraulic, pneumatic, manual, etc
Nominal diameter is 5000 mm
Specific size and structure according to order
A, metal hard seal: attack sealing surface for carbide, valve plate seal face for wear resistant stainless steel.
B, soft seal, valve seat sealing surface of the metal, valve plate seal face for single rubber strip.
C, double soft seal, valve seat sealing surface of the metal, the valve plate seal face for double rubber strip.
D, metal and soft seal, valve seat sealing surface for carbide, valve plate seal face for wear resistant stainless steel with single rubber strip.
Connecting rod mechanism is the core of the connecting rod to cut off the butterfly valve components
A full set of friction pair German imports
High temperature resistant, friction resistance, corrosion resistance and other characteristics
The service life is long
Open valve, the valve plate seal face parallel to the valve seat sealing surface from a distance, and then sit reverse action.
Close the valve, the valve plate first as roll, nearly closed position, the valve plate seal face parallel to the valve seat sealing surface translation closed the distance.
Open and close the valve, sealing surface does not have any relative friction, so to ensure the use of performance and long service life of the valve.
Valve plate closed, due to high-speed fluid through the space between the sealing surface, make the sealing surface with a self-cleaning, not easy to adhere to foreign body or sealing surface.
