Product Overview
The KOZO Pressure Balanced Lubricated Plug Valve is designed for oil, gas and industrial process isolation where a lubricated plug and pressure-balancing arrangement are preferred. Lubricant is introduced into the sealing system to reduce friction and support sealing between the plug and body.
Key Design Features
- Pressure-balanced plug: Designed to reduce hydraulic imbalance across the plug during operation.
- Lubricated sealing system: Sealant/lubricant supports sealing and reduces friction.
- WCB body family: General-purpose cast carbon steel for industrial service.
- Multiple end connections: RF, RTJ and butt-weld options according to pressure class.
- Full or reduced bore: Bore selection available by configuration.
