Middleeast Valve is the greatest Plug Valve Manufacturer in Saudi Arabia, supplying engineered plug valve solutions for oil & gas, petrochemical, water treatment, power and industrial process plants. Our Twin Seal Plug Valve range is built for tight shut-off, low torque operation and straightforward maintenance in demanding pipeline and process applications. Engineering, material selection and testing are applied to meet project specifications across Saudi Arabia.
What is a Plug Valve?
A plug valve is a rotary valve that uses a cylindrical or tapered plug to start, stop or divert flow. The plug contains a through-bore that aligns with the pipeline when open and turns to block flow when closed. Plug valves are valued for simple quarter-turn operation, compact footprint and rapid isolation. Design options lubricated, resilient-sleeve or metal-seated allow selection for different pressures, temperatures and media.
Twin Seal Plug Valve
The Twin Seal Plug Valve features a dual sealing arrangement that provides two independent barriers between the process and the atmosphere. Typically, this includes primary and secondary seats (resilient or metal) separated by a sealed cavity or lubrication chamber. The twin-seal layout improves leakage tolerance if one seat is compromised, the second seal limits leakage until maintenance can be scheduled. These valves are suited to pipeline isolation, emergency shut-off and services where low fugitive emission and enhanced seat life are required.
Key advantages of Twin Seal Plug Valves:
Dual-barrier sealing for enhanced leak containment.
Low operating torque, easing actuation and actuator sizing.
Serviceable seats and plugs for simplified maintenance.
Suitable for bi-directional flow and fast shut-off.
Options for metal-seated or resilient seats depending on media and temperature.
Types of Plug Valves We Supply
Twin Seal Plug Valve – Dual sealing for critical isolation.
Lubricated Plug Valve – Sleeve & lubrication chamber for improved sealing and reduced wear.
Non-Lubricated / Resilient-Sleeve Plug Valve – Low maintenance, elastomeric seating for general services.
Eccentric / Offset Plug Valve – Reduced seat friction for abrasive media.
Multi-Port Plug Valve – For diversion and complex flow routing.
