The Full Port Lubricated Plug Valve is a quarter-turn isolation valve with a full-bore flow passage that minimizes internal flow restriction. Its lubricated plug construction supports low-friction operation and sealing performance for pipeline isolation under specified pressure, temperature, and service conditions.

Lubricated Sealing & Maintenance
Lubricant Replenishment
A grease port allows lubricant to be replenished without removing the valve from the pipeline. Lubricant type and replenishment requirements depend on the valve configuration and service conditions.
Lubricated Plug
Lubrication reduces friction between the plug and sealing surfaces during operation and supports the sealing interface. The lubricant can be specified according to the required temperature and medium conditions.
Typical Service Conditions
Oil & Hydrocarbon Pipelines
Crude oil and hydrocarbon transmission lines requiring full-port isolation.
Water Transmission Systems
Water transmission and municipal pipelines where a full-bore passage is preferred.
Chemical Process Lines
Chemical services compatible with the valve materials and operating limits.
Petrochemical Systems
Petrochemical process and transfer lines requiring lubricated plug isolation.
Configuration & Customization
Material Selection
Body and plug materials can be specified according to the process medium, temperature, pressure class, and project requirements.
Connection & Actuation
End connections and actuation can be specified according to the piping arrangement, valve size, operating torque, and control requirements.
Project Requirements
Customer drawings, dimensional requirements, actuator details, and other project-specific specifications can be reviewed before production.
Inspection & Documentation
Visual & Dimensional Inspection
Valve construction, key dimensions, end connections, and nameplate details are checked against drawings and applicable standards.
Pressure Testing
Shell and seat leakage tests are performed according to API 598 or API 6D, as applicable.
Operation & Lubrication Check
Plug operation, lubrication points, and lubricant injection function are checked before shipment.
Fire-Safe Verification
API 607 fire-safe requirements are applied where specified for the valve configuration.
Inspection Documentation:
Material certificates, pressure test records, dimensional inspection records, and other specified inspection documents can be supplied with the order.
FAQ
Q: What is the MOQ for Full Port Lubricated Plug Valves?
A: MOQ depends on valve size, material, pressure class, and order requirements. The applicable quantity is confirmed with the quotation.
