When you disconnect your couplers, you might discover that some of them spill. If this is the case, you'll need to replace them with dripless couplers. Regardless of the type of fluid you're using or the pressure, there are couplers that rely on poppet systems known as valving to stop dripping. They are completely flush with each other to stop dripping.
The Need for Couplers
When you're moving fluids from one location to another, such as when you are working with hydraulic systems, couplers are essential. They allow for two components to be connected so that fluids can flow from a hose or tube into another part of the hydraulic system, for example. However, when a fluid leaks out, this may cause issues both for the hydraulic system and also for the surrounding work environment.
How Dripless Couplers Work
A dripless, or non-spill, coupler is designed to reduce spilling from couplers to near zero. In some industries, a dripless coupler is an absolute requirement. In some industries, minimum air intrusion is essential to maintain accuracy. In other industries, non-dripping couplers are needed to ensure a high-quality product.
If your product relies on expensive electronics, it may also need dripless couplers. Non-spill connectors reduce fumes and air bubbles, which plays an important role in quality control, especially in the printing industry.
Sanitary Dripless Couplers
When choosing a coupler, make sure that it is sanitary. There are some designs that can trap liquids and will allow bacteria to form. There are other designs that create dead space between the two connections to make sure that they're airtight and don't allow any bacteria to enter.
The filler needs to have the right thickness because the wrong filler will cause the coupler to jam. The most sanitary couplers are those that use the the butterfly design. They can be easily drained and can be sanitized using steam. As a result, they can be used in food, pharmaceutical, cosmetic and semiconductor industries.
Non-Metallic Dripless Couplers
High pressure non-spill couplers are usually made out of metal because metal is often seen as the only material that can handle high-pressure situations. However, lower pressure applications can rely instead on plastics, which are less expensive and lighter.
They might be more practical under some circumstances. There has also been a gradual move from metal to engineered polymers. Therefore, if you have old non-spill couplers, you may want to replace them with newer non-metal versions. For more information, contact a supplier who offers couplers.
