Bolted Bonnet Swing Check Valve
Description
Overview
Bolted Bonnet Swing Valves are full ported, designed for fast check valve action and maximum service life.
- Reliable Operation – Valves are designed to close quickly with positive shutoff in either horizontal or vertical (flow up) pipe runs. The body seat ring is installed on a 3° or 5° angle. This allows our swing check valve to close completely even when installed in a horizontal pipe run with no flow.
- Easy Maintenance – Our bolted bonnet design is simple to disassemble, easy to maintain. For example, our threaded seat rings are easily accessible for repair or replacement.
- Long Life – Our rugged hinge pin/hinge and disc construction is designed to withstand the shock of quick closing and provides years of service. Anti-rotation lugs on discs extend service life in turbulent, high velocity services which can otherwise cause spinning and wear.
