✨ Key Product Features

Innovative Design: Features a novel, rational, and compact structure, ensuring quick opening and closing performance.
Excellent Sealing: Provides superior bi-directional zero leakage sealing due to the high-quality, reliable, and replaceable sealing components.
Low Operating Torque: Requires a low operating torque, making operation easy, convenient, and labor-saving.
Flow Characteristics: The flow characteristic curve tends toward a straight line, offering good throttling/regulation performance.
Installation Flexibility: Installation is convenient via the flanged ends. The valve can be installed in both vertical and horizontal positions.
Long Service Life: The sealing material (Elastomer/PTFE) is resistant to aging and corrosion, contributing to a long operational lifespan.
Pipe End Use: The valve can be reliably used at the end of a pipe run, such as an air vent valve.
