Dry Disconnect Couplings for High-Viscosity Fluids
Resins, adhesives, syrups and other high-viscosity fluids pose significant challenges for manufacturers, but Control Devices’ Dry Link dry-disconnect couplings, which are drip free and lightweight, are designed to keep transfers of difficult media safe, clean and fast, with no spills and no downtime.
This blog highlights the features of these dry-disconnect couplings and how they optimize transfers of high-viscosity fluids.
Challenges of High-Viscosity Fluid Transfer
Transferring highly viscous fluids can be difficult because of the inherent resistance to flow and high pressure drops, which slow down workflows, decrease efficiency and cause mechanical failure of valves.
Key Features of Dry Link for Viscous Media
Control Devices’ Dry Link dry-disconnect couplings are engineered to overcome the challenges of transferring high-viscosity fluids. They offer:
Smooth Bore Design: Minimal internal components allow for high flow rates and the lowest pressure drop available.
Butterfly Valve Shutoff: Unlike poppet valves, which trap thick media and are subject to mechanical failure, a butterfly disc provides a direct flow path, preventing build up and “gunking,” which can cause mechanical failure.
Safety Interlock: This feature prevents accidental opening, ensuring safety and compliance even when transferring high-pressure, thick fluids.
Control Devices’ Dry Link Products for Highly Viscous Fluids
Control Devices offers the following Dry Link products for highly viscous fluids:
Standard Couplings (SS316 & Alloy 20): The primary solution for bulk transfer of viscous chemicals and oils; up to 50% lighter than competitors.
Sanitary Couplings: Feature 20 RA micro-inch mirror finishes, which are ideal for thick food ingredients or pharmaceutical gels where bacterial trapping must be avoided.
Hastelloy C Series: Specialized for corrosive high-viscosity fluids that require maximum chemical resistance.
Keyed Couplings: Ensure high-viscosity batch processes remain uncontaminated by preventing incorrect connections.
Optimize Your High-Viscosity Workflow
Dry Link dry-disconnect couplings are drip and spill free to protect employees and the environment and offer better flow, helping you conserve every drop of material and avoid costly cleanup to optimize fluid transfer operations.
No Drips: Dry Link couplings trap fluids so they don’t drip onto the ground. The flow shut-off mechanism resembles a butterfly valve with very low flow restriction, enhancing flow and reducing the risk of buildup that can lead to failure. A safety interlock prevents accidental opening and a unique sealing arrangement provide a drip-free dry disconnect. This helps eliminate costly cleanup and aids compliance with U.S. Environmental Protection Agency standards.
Efficient Transfers: Dry Link couplings are up to 50% lighter and more compact than comparable dry-disconnect couplings and use fewer internal components for maximum flow. The easy hose alignment and simple maintenance allow more efficient operations, while the enhanced flow speeds up the process.
