Dual Plate Lug Check Valve

Dual Plate Lug Check Valve Suppliers in UAE: Compact Solution for Backflow Prevention

Middle East Valve is a well known Dual Plate Lug Check valve suppliers in UAE. It is a check valve that is used to avoid backflow in a piping system. It consists of two spring-loaded plates (or discs) that close automatically in case of a reversal of flow. The lug-type body enables simple installation between flanges using bolts, making it ideal for close or limited-space systems.

 Components:

1. Valve Body (Lug Type) – made for simple bolting between pipe flanges
2. Dual Plates/Discs – swing open on forward flow and close on reverse flow
3. Spring Mechanism – provides fast and positive closing action
4. Seat – ensures leak-tight sealing
5. Stop Pin and Hinge – direct the plates’ movement

Working Mechanism:

When fluid moves in the proper direction, pressure opens the two plates. When flow ceases or reverses, the springs cause the plates to return to the closed position, thus avoiding backflow. The spring-aided construction provides quick response time and reduces water hammer and is thus suitable for use in variable flow conditions in systems.

Advantages:

• Lightweight, small in size, and easy to install
• Avoids backflow and safeguards pumps and equipment
• Lug design facilitates simple removal and maintenance
• Low pressure drop due to streamlined design
• Corrosion-resistant and appropriate for harsh environments
