Product Description

 

Product Description

Introduction:

The pneumatic wafer butterfly valve features a simple structure, low flow resistance coefficient, and a flow characteristic close to a linear curve, with no residue retention.

Product Advantages:

• Compact and lightweight, easy to disassemble and maintain, and can be installed in any position.
• Simple and compact structure, low operating torque, quick 90° rotation for fast opening.
• Flow characteristic tends to be linear, with good regulation performance.
• The connection between the butterfly plate and valve stem adopts a pinless structure, overcoming potential internal leakage points.
• The outer circle of the butterfly plate is designed with a spherical shape, improving sealing performance and extending the valve's service life. It can withstand over 50,000 pressurized open/close cycles while maintaining zero leakage.
• Sealing components are replaceable, ensuring reliable double-directional sealing.
• The butterfly plate can be coated with materials like nylon or PTFE, according to user requirements.
