Keckley Strainers are available in the materials required for most applications, including highly corrosive fluids. All castings are supplied in strict adherence to ASME and ASTM specifications. Cast iron is the least expensive and most often used material. Bronze is widely used for marine service in salt water. Carbon steel is used in the oil and petrochemical market, where greater strength and resistance to mechanical and thermal shock are important. Stainless steel strainers are used in the food, pharmaceutical and chemical industries, where high resistance to corrosion or contamination free conditions is necessary The screen or basket is the heart of the Keckley Strainer. The media flows into the open end of the screen or basket and is strained as it passes through the screen toward the outlet. All particles too large for screen or basket perforations are trapped inside. Screens are provided in perforated metal or wire mesh, depending on strainer size and/or material being strained.
Duplex strainers are used in continuous flow applications where the process can not be shut down for cleaning. Examples: lubrication systems, industrial or marine oil burners, chemical plants, cooling lines in power plants, compressors, condensers, and ink supply lines to printing presses. Duplex strainers are also specified for water lines to cooling towers and pumping stations where water is taken from lakes or rivers.
Keckley is the premier supplier of perforated and mesh replacement screens for Y, Basket, Duplex, Fabricated and Temporary Strainers. Screen material come in 304 stainless steel, 316 stainless steel, bronze, monel, and specail alloys.
Cast Iron, 316 Stainless Steel and Carbon Steel, Wafer Double Disc Check Valve, Wafer Silent Check Valve, Globe Silent Check Valve:Liquid or gas where protection from flow reversal in a pipeline is required.
Float valves and lever valves are designed to control the level of liquids through mechanically actuation. Float valves are actuated through the attached float ball, float rod, and lever assembly and do not require any external power source. Lever valves are actuated through the use of some external power source such as manual operation, float boxes/mechanisms, electric motors or other actuators, through external linkage to the lever of the valve.
