Product Overview
Pneumatic regulating butterfly valve series products, is a long life, energy saving butterfly valve. lts structure adopts the principle of three-dimensional braided design, the valve seat USES the hard and soft seal compatible multi-level structure, the technology is advanced, the processing is exquisite.Thisproduct is composed of valve body, butterfly plate, multi-level seat, stem, transmission mechanism and other main components.
Structural Characteristics
Because the butterfly valve of this product is designed based on the principle of three-dimensional eccentricity, the space movement track of the sealing surface is idealized, and there is no friction and interference between the sealing surfaces. In addition, the optimized configuration of the sealing materials makes the sealing performance, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve be reliably guaranteed.
Its main characteristics are as follows:
- Small opening torque, flexible and convenient, labor-saving and energy-saving.
- The three-dimensional core structure makes the butterfly plate closer and tighter. Its sealing performance is reliable and no leakage is achieved.
- High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
