Clean Valve

Designed for use on glass-lined reactors where batch-to-batch cleanability is important, the Clean Valve is a bottom-flush valve that is easy to operate and clean. The self-draining valve allows for a variety of functions (including sampling, gas dispersion, maintenance, etc.) without the need to interrupt the process and without dismantling the valve. The glass-linedsteel design ensures no metal contamination of the process fluid and enables use across a wide temperature and pressure range. The valve seat seals against the bottom outlet nozzle to prevent any collection or build-up of materials in the annular area between the valve seat and nozzle wall. An additional port with a 5-deg. downward sloping angle has been built into the valve to facilitate cleaning of the internal components and body. The Clean Valve features a UniTIP glass-lined steelhead and stem that is machined to provide a smooth-sealing surface for the valve-packing sealing rings. A Teflon-encapsulated Viton O-ring seal located in front of Chevron packing within the sealing neck provides a primary seal and positive sealing against the valve body to eliminate the accumulation of process material above the Chevron packing.
