PLUG VALVES
The Flow Control Group supply a complete range of Plug Valves for a wide range of applications in the water, wastewater, oil and gas and industrial process sectors.
The specification and selection of a valve and its operating protocols is essential to the optimum performance of any valve. The Flow Control team have the knowledge and expertise to identify the correct valve for the desired application.
Eccentric Plug Valves can be used for either isolation / shutoff or throttling / control services. They are ideal for handling clean and dirty liquids, sludge, slurries and gases. Eccentric plug valves are available in sizes from 15-1800 mm with a temperature range of up to 150 degrees Celsius. They are available with resilient plug facings for drip tight bi-directional shutoff, or metal plugs that provide shutoff per ANSI/FCI 70-2 Class IV. The welded nickel seat provides the best protection against seat corrosion that can cause plug face damage and leakage. The raised seat provides an area for solids to be pushed away, ensuring positive closure. Cast iron valves are pressure rated to 175 psi CWP as standard in .5 to 12 inch sizes; cast iron valves 14 inch and larger are rated to 150 psi. Ductile iron valves are rated to 285 psi in sizes 12 inch and smaller; ductile iron valves 14 inch and larger are rated to 250 psi.
Eccentric Plug Valves have been used successfully to meet the application requirements of water and wastewater (sewage) treatment; pulp & paper; chemical and petrochemical; power; mining; steel; and other process industries.
Three-way and Four-Way Plug Valves are used for throttling and diverting applications. They are available in 3-16 inch sizes and are pressure rated to 125 psi CWP with temperatures up to 400 degrees Fahrenheit. The multiple-port design with the single or double tapered plug styles can be arranged into a variety of flow combinations. Resilient seated plugs are available for dead-tight shutoff with lever and double handwheel actuators. All metal plugs are available for high temperature applications that do not require dead-tight shut off. Standard body materials include cast iron, aluminum, carbon steel, and 316 stainless steel with higher alloys available on application. Three-Way and Four-Way valves handle clean, dirty, viscous, and corrosive liquids, as well as sludge, abrasive and fibrous slurries, and clean and dirty gases.
