Camlock-DC Couplings: A Specialized Cam-Lock Quick-Connect Solution for Liquid Transfer

Camlock-DC couplings represent a specific type of cam-lock quick-connect fitting, uniquely designed for liquid conveyance applications. Their core functionality lies in the cam-lock mechanism, which enables rapid connection and disconnection without the need for tools, significantly enhancing operational efficiency. These couplings are particularly well-suited for scenarios requiring frequent assembly and disassembly, such as equipment maintenance and temporary pipeline connections.

Material Composition and Corrosion Resistance

The main body of Camlock-DC couplings is crafted from either 304 or 316 stainless steel, both renowned for their exceptional corrosion resistance.

• 316 Stainless Steel: Enhanced with molybdenum, 316 stainless steel offers superior resistance to chloride corrosion, making it ideal for highly corrosive environments such as seawater and chemical media. It complies with FDA and USP sanitary standards, allowing direct use in the food and pharmaceutical industries.

• 304 Stainless Steel: With its strong versatility and relatively lower cost, 304 stainless steel is suitable for general industrial liquid transfer applications involving non-strongly corrosive media like water and oil products.

Performance Specifications

Working Pressure

• Conventional models of Camlock-DC couplings can withstand a maximum pressure of 250 psi for 1-1/2 inch and 2-inch sizes, while 3-inch and 4-inch models are rated at 150 psi. These pressure ratings meet the requirements of most low-pressure fluid transfer applications.

Temperature Range

• The couplings operate effectively across an extensive temperature spectrum, ranging from -101℃ to +260℃. This wide range allows them to handle extreme cold conditions as well as high-temperature steam applications.

Sealing Performance

• Equipped with sealing rings made from materials such as Nitrile Butadiene Rubber (NBR), Fluorocarbon Rubber (FKM), and Polytetrafluoroethylene (PTFE), Camlock-DC couplings can adapt to various media characteristics. This ensures long-term, leak-free performance, even under challenging conditions.

Interchangeability Standards

Camlock-DC couplings adhere to stringent interchangeability standards, including the US military standard A-A-59326 and the European standard DIN 2828/EN 14420-7. These standards guarantee compatibility with products from other brands, facilitating seamless integration into existing systems and enhancing operational flexibility.

In summary, Camlock-DC couplings offer a reliable, efficient, and versatile solution for liquid transfer applications. Their robust construction, wide performance range, and adherence to international standards make them an excellent choice for industries requiring frequent and reliable connections and disconnections.
