Electric Triple Offset Butterfly Valve The electric triple eccentric butterfly valve adopts a three-dimensional eccentric structure, and has the advantages of strong applicability, small torque force, less friction, and good sealing performance. When the electric triple eccentric butterfly valve is opened, the disc will instantly separates the sealing surface of the seat, which reduces friction and interference with the sealing surface, and greatly improves the service life of the butterfly valve. Moreover, the electric triple eccentric butterfly valve disc and the seat sealing surface are made of stainless steel, so that the butterfly valve has reliable guarantee of corrosion resistance, temperature resistance, pressure resistance and wear resistance, and is a high-performance energy-saving electric butterfly valve. Specification: Model: D943H, D973H Size: 2~48 Pressure Rating: Class150~600LB Main Materials: WCB, LCB, CF8, CF8M Seals: Soft Seal or Metal Seal Suitable Temperature:-40~450 Design and Manufacture: API 609 Face-to-Face: API609, ASME B16.10, ISO 5752 Ends Connection: Flange, Wafer, Lug, Butt-Welded Inspection & Testing: API 598, EN12266 Operation: Lever, Electric, Pneumatic, or Hydraulic etc. Actuator: Supply Power: AC220V, AC380V Acting Range: 0-90° Device: Explosion-proof, can be equipped with manual device Control Type: On-off, or intelligent adjustment (4-20mA analog signal control). Feature: The electric triple eccentric butterfly valve has the dual features of metal sealing and elastic sealing. Excellent sealing performance regardless of low temperature or high temperature. Mainly used in petroleum, chemical, electric power, metallurgy, steel, paper, medicine, food, textile, light industry, etc.

The valve body and disc is all adopted QT450-10 material, the ball rate is above grade 3, the mechanical performance is fully up to standard, the tensile strength is 450Mpa, and the elongation rate is more than 10%. It is not easy to crack or freeze. The valve body is solid body, the same caliber weight is heavier than others. Seat uses standard EPDM rubber, making the butterfly valve's resilience and tension super stable and reliable, opening and closing more than 10,000 times without leakage. The valve body uses an electrostatic powder thermal spraying process with a spray thickness of 250μm. The valve body is heated at 200°C for 3 hours, and the powder is cured at 180°C for 2 hours. After natural cooling, the surface adhesion is increased by 2 times than that of the ordinary powder, making it more environmentally friendly and weatherproof. Higher, to ensure that the valve body is not discolored for 36 months.

Sudhanafluid pneumatic valve series: butterfly valve The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis with a rotation angle of 0 �°~90 �°. When the rotation angle reaches 90 �°, the valve is fully open. The butterfly valve is simple in structure, small in volume and light in weight, and only consists of a few parts. Moreover, the valve can be quickly opened and closed only by rotating 90 �°, which is simple to operate. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate. The valve with metal seal is generally longer than the valve with elastic seal, but it is difficult to achieve complete sealing. The metal seal can adapt to higher working temperature, while the elastic seal has the defect of being limited by temperature. If the butterfly valve is required to be used for flow control, the main thing is to correctly select the size and type of the valve. The structure principle of butterfly valve is especially suitable for making large diameter valves. Butterfly valves are not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power plants. There are two kinds of butterfly valves commonly used: wafer type butterfly valve and flange type butterfly valve. Wafer type butterfly valve uses stud bolts to connect the valve between two pipe flanges. Flange type butterfly valve has flanges on the valve, and bolts are used to connect the flanges on both ends of the valve to the pipe flanges.
