Product Overview
The KOZO Class 2500 Pressure Seal RTJ Gate Valve is intended for high-pressure steam, power and process isolation where a pressure-seal bonnet and ring-type-joint flange connection are required. The wedge gate provides full-bore isolation with low pressure drop when fully open.
Key Design Features
- Pressure-seal bonnet: Internal pressure increases the sealing load of the bonnet joint.
- RTJ flanged ends: Reference connection for high-pressure piping systems.
- Wedge gate: Straight-through isolation with low flow resistance when open.
- Hard-faced trim: Reference WC9 + Stellite wedge/seat treatment for demanding service.
