Product Overview
The KOZO Class 2500 Pressure Seal Tilting Disc Check Valve is designed for high-pressure piping where fast non-return action, pressure-seal construction and butt-weld installation are required. The disc pivots through a shorter travel than a conventional swing check valve, helping reduce closing time.
Key Design Features
- Tilting-disc non-return mechanism.
- Pressure-seal bonnet for high-pressure service.
- Butt-weld ends for welded piping systems.
- WCB/WC9 material options by configuration.
- Automatic operation without an actuator.

Selection Notes
Check-valve dynamics depend on flow velocity, orientation, minimum flow, pressure drop and system transients. Valve sizing should consider the actual operating envelope rather than line size alone.
