D673H Pneumatic Wafer Butterfly Valve

Pneumatic Wafer Butterfly Valve Product Overview

The company's D673H\D671X pneumatic wafer butterfly valve is the conventional butterfly valve preferred for pipelines, typically categorized into pneumatic wafer soft-sealed butterfly valves and pneumatic hard-sealed wafer butterfly valves. The pneumatic wafer butterfly valve features a simple structure, low flow resistance coefficient, linear flow characteristics, and does not trap debris. It is lightweight, easy to install, and requires low driving torque. The pneumatic wafer butterfly valve can be used both for cutting off media and for regulating media flow. The valve body can be equipped with components made of different materials and paired with sealing rings of various materials to adapt to different media and working conditions, achieving an optimal balance between cost and performance. The pneumatic wafer soft-sealed butterfly valve is suitable for temperatures ≤120°C or ≤150°C. The pneumatic hard-sealed wafer butterfly valve is suitable for temperatures ≥200°C or ≤450°C, with a nominal pressure ≤1.6MPa. It is widely used in industries such as water supply and drainage, sewage, food, heating, gas, shipping, hydropower, metallurgy, energy systems, and light textiles. It is particularly suitable for bidirectional sealing applications and environments where the valve body is prone to corrosion, serving to regulate flow and cut off media.

Pneumatic Wafer Butterfly Valve Product Features

(1) Compact and lightweight, easy to disassemble, maintain, and install in any position.
(2) Simple and compact structure, low operating torque, and quick 90° rotation opening.
(3) Linear flow characteristics, excellent regulating performance.
(4) The connection between the disc and the valve stem adopts a pinless structure, eliminating potential internal leakage points.
(5) The disc's outer circle features a spherical design, enhancing sealing performance and extending the valve's service life. It maintains zero leakage even after over 50,000 pressure cycles.
(6) The sealing components are replaceable and provide reliable bidirectional sealing.
(7) The disc can be coated with materials such as nylon or PTFE as per user requirements.
