Consolidated* 1811 Series Safety Valve Overview The Consolidated Type 1811 safety valve from GE is a cost-effective, high- capacity, flanged steel safety valve designed for steam service. Features and Benefits • variety of pressure/temperature classes, orifice sizes and inlet/ A outlet combinations provide a flexible selection of safety valves to meet industrial needs at the lowest cost. • ow spindle bearing point and concentric spindle loading L virtually eliminate the natural tendency for the disc to assume a horizontal position during the opening and closing cycle of the valve. • he mechanical flexibility of the Thermodisc* allows the system T pressure to assist in sealing the contact surface between the valve seat and Thermodisc.. • eal welding the seat bushing into the base assures no leakage of S steam past the threaded area of the seat bushing. • ual ring adjustments allow fine tuning of the safety valve D performance characteristics needed to meet the steam system conditions that vary at each installation. A sharp, clean opening assures long valve seat life and reduced maintenance costs . Consistent opening and closing pressures contribute to efficient steam system operation. Because the 1811 valve is not totally enclosed, upon actuation the system media will escape from the following locations: 1. The valve outlet that is the main discharge area. 2. The open yoke, which will also allow a small amount of steam to exhaust vertically. 3. The drain hole at the base of the valve. fact sheet
