CONSOLIDATED TYPE 1811 safety valve is a cost effective, high capacity, flanged steel safety valve designed for steam service
Features & Benefits
• A variety of pressure/temperature classes, orifice sizes and inlet/outlet combinations provide a flexible selection of safety valves to meet industrial needs at the lowest cost
• Low spindle bearing point and concentric spindle loading virtually eliminates the natural tendency for the disc to assume a horizontal position during the opening and closing cycle of the valve
• The mechanical flexibility of the ThermodiscTM allows the system pressure to assist in sealing the contact surface between the valve seat and ThermodiscTM
• Seal welding the seat bushing into the base assures no leakage of steam past the threaded area of the seat bushing
• Dual ring adjustments allow fine tuning of the safety valve’s performance characteristics needed to meet steam system conditions which vary at each installation. Sharp, clean opening assures long valve seat life and reduced maintenance cost. Consistent opening and closing pressures contribute to efficient steam system operation
