Manufacturer of high quality valves for Process service; Pneumatic Conveying; Diverting of abrasive, erosive media and Boiler Blow Down. If you are repairing or replacing the installed valve more than once a year, this is the valve for your application.

ISO 9001 Certified

Rotating Disc Valves include hard metal sealing surfaces for handling abrasive, erosive slurries and dry powdered media. Open body allows free flowing media and fines to be displaced by moving parts, therefore no packing or jamming.

Everlasting Valves were developed for steam boiler blow down nearly 100 years ago for abrasive solids. The packaged steam boiler industry has standardized on the everlasting valve rotating flat disc boiler blow off valve. This boiler blow down valve is available in quick opening, slow opening straight and angle configurations. They are manual on-off valves that effectively blow down sludge formed in steam boilers.

The Everlasting air cylinder actuated two-way Process Valve is used in dry powders or slurries of erosive media for pump isolation, reactor fill and discharge and are available in Diverter (1 in 2 out) configuration. The Everlasting rotating disc Process design is suitable for temperatures to 1500f, pressures to 10,000 psig handling abrasive particulate, it is not affected where ploymerization gums up other valves that were designed for clear fluids, not solids.

Everlasting rotating disc Diverter valves can be switched without stopping the conveying compressor, is used for slurries and dry powders including Portland Cement, bottom and fly ash, Titanium Dioxide, Tabluar Alumina, Alumina Silica, Kaolin, Raney Nickel Catalysts and metal silicon powders. The Diverter valve is available in cast iron or fabricated of Carbon or Stainless Steel or other alloys with manual or air cylinder actuation.

The everlasting rotating disc air cylinder actuated Bulk Material Valve was designed for pressurized (to 100 psig) and vacuum systems including dense and dilute phase pneumatic conveying systems, for transporter fill valve, discharge, and vent applications, transfer lines, under baghouses, silos and dust collectors. When two Bulk Material Valves are installed in a wye fitting the valve becomes an effective diverter.

Everlasting Valves have replaced knife gates, pinch valves, slide gates, rotary air lock, double dump, ball and plug valves.
