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.
How to Specify This Valve
Please provide size, class, medium, design pressure, temperature, body/trim material, weld-end preparation and testing requirements.
