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
•t 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.
•t 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.
•t he mechanical flexibility of the Thermodisc* allows the system
T
pressure to assist in sealing the contact surface between the
valve seat and Thermodisc..
•t eal welding the seat bushing into the base assures no leakage of
S
steam past the threaded area of the seat bushing.
•t 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.

Note:

Because the 1811 valve is not totally enclosed, upon actuation the system
media will escape from the following locations:
1.t The valve outlet that is the main discharge
area.
2.t
The open yoke, which will also allow a small amount of steam to
exhaust vertically.
3.t The drain hole at the base of the valve.
