Capacity: 1-2 ton Size: standard Brand: VE Color: brass Material: brass Customisation: Not Customised Nrv injection packers, also known as non-return valve injection packers, are a specific type of injection packer used in grouting applications. They differ from other packers in their unique feature of a built-in non-return valve, offering additional benefits in certain situations. Here's a breakdown of nrv injection packers: How They Work: Like other packers, they create a tight seal against the crack or void walls to allow for pressure injection of grout. The key difference lies in the non-return valve, which allows grout to flow into the crack but prevents it from flowing back out once injected. This ensures: Complete filling of the crack: No grout leaks back out, allowing for thorough and efficient crack filling. Reduced pressure release: Pressure remains within the crack, providing better bonding and crack stabilization. Cleanliness during removal: After injection, the valve prevents remaining grout from spilling out when the packer is removed. Benefits of Nrv Injection Packers: Improved grouting effectiveness: Ensures complete crack filling and optimal grout bonding within the crack. Reduced pressure loss: Maintains pressure for better crack stabilization and minimizes material waste. Cleaner work environment: Prevents grout leaks during packer removal, improving operator safety and jobsite cleanliness. Suitable for challenging applications: Ideal for situations with high water pressure or potential backflow. When to Use Nrv Injection Packers: Cracks under hydrostatic pressure: For cracks submerged in water or subject to groundwater pressure. Deep or inaccessible cracks: When complete filling and controlled pressure are crucial. Leak repair applications: Sealing leaks where preventing grout backflow is essential. Cleanroom or sensitive environments: Minimizing grout spills protects sensitive equipment or surfaces.
