Fittings, Valves & Actuators

For many industrial and commercial applications, Dwyer fittings and valves play an essential role. They offer precision, durability, and reliable performance in control and fluid handling systems. Dwyer's ball valves, check valves, and needle valves are used in a variety of systems to regulate the flow of gases and liquids, including those in HVAC (heating, ventilation, and air conditioning), water treatment, and process automation.

Secure, leak-proof connections among pipes, tubes, and system components are a necessity in industrial applications. Dwyer has a complete line of fittings for just that purpose. Compression fittings and quick-connect fittings, for example, are two types of Dwyer that work very well to make connections safe and reliable. 

Dwyer's valves and fittings are known for their durability and reliability, whether they are being used for exact pressure control, flow regulation, or dependable connections in piping systems. They are vital to maintaining the efficiency and safety of many industrial processes, doing their jobs so well that they are used in a wide variety of applications across many, many industries.
