Oil and Gas Field
Oilfield extraction and transport
Used for pipeline opening and closing and flow control of crude oil, natural gas, liquefied gas, especially excellent in impurity-containing media (self-cleaning design reduces particle build-up).
Oil-sealed plug valves are suitable for high-pressure working conditions (up to 64 MPa) by forming an oil film through forced lubrication.
Oil refining equipment
Control diversion and shut-off of high temperature oil (≤340℃) in the refining process.
Chemical and corrosive media handling
Strong corrosive media control
Fluorine lined plug valves (PTFE/PFA lining) are suitable for corrosive fluids such as concentrated acid, alkali.
Containing particles or viscous fluids
Cemented carbide sealed plug valve can handle slurry, crystalline liquid and high viscosity media.
Industrial process control
Multi-channel media distribution
Three-way / four-way plug valve to achieve single-valve control of multi-channel flow (such as reactor feed switching).
High-temperature and high-pressure scenarios
Metal hard seal plug valve for steam system (≤ 425 ℃) and high temperature reaction device.
Utilities and environmental protection
Water treatment system
Municipal water supply, sewage treatment in the flow regulation and cut-off (DN15-DN500 calibre).
Fire fighting and HVAC
Rapid opening and closing of fire-fighting pipelines, heat medium distribution of HVAC system.
Special Scenario Applications
Aviation and Automobile
Aviation paraffin filling control, oil/coolant discharge in automobile maintenance.
Food & Pharmaceutical
Sanitary plug valves to meet the requirements of aseptic processes (need to comply with FDA standard materials).
