Types of Davis Valves
Knife Gate Valves
Knife gate valves are designed for on/off control of flow in applications involving slurries, viscous fluids, and solids. The design features a sharp-edged gate that slices through the material, providing effective sealing. These valves are extensively used in the pulp and paper industry, mining, and wastewater treatment facilities. They are available in sizes from 1/2″ to 36″ and can be made from various materials, including stainless steel and cast iron.
Wafer Check Valves
Wafer check valves prevent backflow in piping systems, ensuring that liquids only flow in one direction. They are compact and lightweight, making them ideal for installations with limited space. Common applications include oil and gas, petrochemical, and HVAC systems where backflow prevention is critical. Sizes range from 1″ to 12″, and they are typically constructed from cast iron or bronze.
Boiler Stop Check Valves
Davis Valve boasts the largest inventory of boiler stop check valves in the USA, making them a reliable choice for maintaining steam systems. These valves are designed to control the flow in boiler applications and comply with ASME Boiler and Pressure Vessel Code. They are available in various sizes and materials, including A-126B cast iron and WCB steel, ensuring durability and longevity.
Ball Valves
Ball valves are essential for providing reliable fluid control in a wide range of industrial applications. They are particularly favored for their ability to offer tight sealing with minimal pressure drop. Davis Valve’s ball valves come in various designs, including two-piece and three-piece configurations, and are available in sizes from 1″ to 36″. Materials such as carbon steel, stainless steel, and exotic alloys like Hastelloy ensure they can withstand harsh operating conditions.
Strainers
Strainers serve the critical function of filtering out particulates from liquids in pipelines. They help prolong the life of downstream equipment by preventing clogging and damage. Davis Valve offers strainers in sizes ranging from 1″ to 12″ and constructed from durable materials, including cast iron and stainless steel, making them suitable for water treatment and chemical processing applications.
Gate Valves
Gate valves are commonly used for on/off control of flow in various applications, including water supply and sewage treatment. Their design allows for minimal flow restriction when fully opened, making them ideal for high-flow applications. Available in sizes from 1″ to 36″, gate valves from Davis Valve can be constructed from cast iron or stainless steel, depending on the specific application requirements.
Globe Valves
Globe valves are primarily used to regulate flow in pipelines. Their unique design allows for precise control, making them suitable for applications such as HVAC systems and water supply. These valves come in sizes from 1″ to 24″ and are typically made from cast iron or bronze.
Swing Check Valves
Swing check valves allow flow in one direction while preventing backflow. They are commonly used in oil and gas applications and water treatment processes. Davis Valve offers swing check valves in sizes ranging from 1″ to 12″ and constructed from durable materials such as cast iron and stainless steel.
Plug Valves
Plug valves are utilized for on/off control with minimal pressure drop. They are especially useful in chemical processing and oil and gas applications. Davis Valve’s plug valves are available in sizes from 1″ to 6″ and are typically made from cast iron or stainless steel.
Butterfly Valves
Butterfly valves are used for regulating flow with quick shut-off capabilities. They are suitable for water supply and HVAC applications and come in sizes ranging from 2″ to 36″. Davis Valve’s butterfly valves can be constructed from cast iron or stainless steel, making them versatile for various industrial settings.
