Product Overview
The KOZO Class 1500 Inverted Pressure Balanced Lubricated Plug Valve is intended for high-pressure oil, gas and process isolation where an inverted plug arrangement, pressure balancing and injected lubrication are required.
Key Design Features
- Inverted plug arrangement: Supports controlled sealing and maintenance in high-pressure service.
- Pressure-balanced design: Reduces hydraulic imbalance across the plug.
- Lubricated sealing system: Sealant supports sealing and reduces operating friction.
- RTJ ends: Reference configuration for Class 1500 piping.
- Worm-gear operation: Controlled manual operation for high torque.
