Pneumatic clamp type hard seal butterfly valve D673H-Fornitore globale

D673HPneumatic clamp type hard seal butterfly valveUsed in industries such as petroleum, chemical, power, metallurgy, food, medicine, textile, paper, etc., it can be installed on industrial pipelines with temperatures ≤ 425 ℃ and media such as gas, air, steam, water, seawater, oil products, etc. for regulating flow and cutting off media.
The driving forms include manual, worm gear transmission, pneumatic, hydraulic, electric, electro-hydraulic linkage and other actuating mechanisms, which can achieve remote control and automated operation. Metal hard sealed butterfly valve series products, energy-saving butterfly valves. Its structure is designed using the three-dimensional core principle, and the valve seat adopts a multi-level structure compatible with hard and soft seals, with exquisite processing and advanced technology. This product consists of main components such as valve body, butterfly plate, multi-level valve seat, valve stem, and transmission mechanism. Applied to pipelines for corrosive media such as metallurgy, electricity, petroleum, chemical, air, gas, combustible gases, and water supply and drainage.

Product features of pneumatic clamp type hard seal butterfly valve
Due to the three-dimensional eccentric principle design used in this butterfly valve product, the spatial motion trajectory of the sealing surface is idealized, and there is no friction or interference between the sealing surfaces. In addition, the appropriate selection of sealing materials ensures the sealing, corrosion resistance, high temperature resistance, and wear resistance of the butterfly valve. Its main characteristics are as follows:

1. Small opening torque, flexible and convenient, labor-saving and energy-saving.
2. The three-dimensional core structure makes the butterfly plate tighter as it is closed, and its sealing performance is reliable, achieving no leakage.
3. High pressure resistance, corrosion resistance, wear resistance, etc.
