The BV 32000 - Refractory lined is designed for temperatures above 1000°C, or where higher pressures are involved, such as a water cooled design.
Experience of Refractory Lined Valves has been for gases at temperatures up to 1200°C with low or negligible pressure. Materials of construction can vary considerably depending upon temperature, pressure, temperature fluctuation, flowing media, particularly in respect to oxidising or sulphurous atmospheres and clients own specifications. We recommend that the refractory cement lining is accurately cast into the body in our works to avoid problems on-site or in service.
Where the flowing media is dirty or dust laden and there is a possibility of internal bearing seizure, the valve may be designed to incorporate outboard bearings
