I. Detailed Information on the Product [Wafer-Type Multi-Level Structure]:

Product Model: D673H

Product Name: Wafer-Type Multi-Level Pneumatic Wafer-Type Hard-Sealed Butterfly Valve

Product Features: Multi-level metal hard-sealed butterfly valve, multi-level sealed butterfly valve, metal hard-sealed butterfly valve

II. Product Structure:

The structure of the multi-level hard-sealed butterfly valve series adopts a three-eccentric principle design. The valve seat adopts a multi-level structure compatible with hard and soft seals, and is composed of main components such as the valve body, butterfly plate, multi-level valve seat, valve stem, and transmission mechanism.

III. Features:

Since the butterfly valve of this product adopts a three-eccentric principle design, the spatial motion trajectory of the sealing surface is idealized, and there is no friction or interference between the sealing pairs. In addition, the sealing material is properly selected, so that the sealing performance, corrosion resistance, high temperature resistance, wear resistance, etc. of the butterfly valve are reliably guaranteed.

Its main features are as follows:

1. Small opening torque, flexible and convenient, labor-saving and energy-saving;

2. The three-eccentric structure makes the butterfly plate tighter when closing, and its sealing performance is reliable, achieving zero leakage.

3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
