Swing Check Valve Introduction

This swing check valve features a one-piece body with a top-entry design, allowing for easy field servicing and convenient inline maintenance.
Engineered for reliable performance, the valve opens automatically with forward flow and closes with reverse flow, making it suitable for both horizontal and vertical (upward flow only) installations.
It offers a low pressure drop, making it ideal for high-velocity flow applications.
The body’s spherical shape with a large radius helps minimize stress, reduce turbulence, and lower flow resistance, enhancing overall system efficiency.
