Plug Valve – Key Features & Advantages
Robust Design
The tapered or lubricated plug ensures bubble-tight sealing, even under extreme conditions.
Bidirectional Flow
Suitable for applications requiring flow reversal without performance loss.
Low Maintenance
Minimal moving parts and corrosion-resistant materials (stainless steel, alloy, or PTFE-lined) extend service life.
Multi-Port Options
Available in 2-way, 3-way, or multi-port configurations for diverting or mixing flows.
Fast Operation
Quarter-turn actuation enables quick on-off control.
Advantages Over Alternatives
Superior sealing performance in gritty or viscous fluids (e.g., slurries, oils).
Compact design ideal for space-constrained installations.
Higher pressure tolerance compared to many gate or ball valves.
Plug Valve: Reliable Flow Control for Demanding Applications
A plug valve is a quarter-turn rotary valve featuring a cylindrical or tapered plug with a hollow passage. By rotating the plug 90 degrees, the valve transitions between fully open and closed positions, aligning the passage with the pipeline to allow flow or blocking it completely for shut-off. Renowned for their simplicity, tight sealing, and durability, plug valves excel in handling high-pressure, high-temperature, and abrasive media.
Lift Type Plug Valve
As China Lift plug valve manufacturer, factory and supplier, Oilong supplies non-lubricated lift type plug valve, jacketed lift plug valve, metal seat lift plug valve.
Lift Plug Valve Specification & Features
Bolt bonnet OS & Y lifting-round plug. Opening and closing of the valve is carried out while the sealed surface is taken off, so it will not cause abrasion on the sealed surface, Bi-direction.
