Author : Middleeast Valve | Published On : 18 Jun 2026

Middle east Valve is one of the leading Lubricated Plug Valve Manufacturers in Saudi Arabia, supplying durable valves to industries in Ajman, Khor Fakkan, and Al Ain. These valves are designed for high-pressure, frequent operation in sectors such as oil & gas, water systems, and chemical processing.

Understanding Lubricated Plug Valves

A lubricated plug valve uses a cylindrical or tapered plug with a through-hole to regulate flow. Its unique feature is a lubricant injected between the plug and body, reducing friction, ensuring smooth rotation, and providing a tight seal. This makes them suitable for abrasive and corrosive applications.

Construction and Components

  • Body – Houses internal parts and connects to the pipeline.
  • Plug – Cylindrical/tapered element with grooves to hold lubricant.
  • Sealant Injection System – Supplies lubricant for smooth operation.
  • Stem – Connects plug to actuator or handle.
  • Seats – Seal between the plug and body.
  • Handle/Actuator – Provides manual or automatic control.

Functionality

  • Operation – A 90° turn aligns or blocks the bore for on/off control.
  • Lubrication – Injected sealant reduces torque and wear.
  • Sealing – Lubricant fills micro-gaps, preventing leakage.

Key Features and Advantages

  • Low operating torque
  • Bubble-tight sealing
  • Resistant to wear and corrosion
  • Suitable for gases, slurries, and viscous media
  • In-line lubrication for easy maintenance
  • Performs under high pressure and temperature
  • Handles bidirectional flow
