Note: Refer to this Table for the performance criteria of this valve. Applications outside of these ranges may cause
malfunction of the intended valve operation.
Table 1: Performance Criteria for the 19096M-DA-BP Valve
Typical blowdown as a percent of set pressure
(at the low end of the spring range with the maximum
allowed back pressure applied, the blowdown is
shortest)
Liquid: 6 percent – 20 percent
Gas: 3 percent – 16 percent
Allowable total back pressure
(this is the sum of the variable and constant back
pressure, superimposed and built-up)
Liquid: 70 percent of set pressure
Note: Thermal relief applications may be supplied with back
pressures up to 90 percent of set pressure.
Gas: 50 percent of set pressure
Note: Total back pressure for liquid or gas shall not exceed
400 psig (27.58 barg)
Temperature limits
(determined by O-ring material selection)
Minimum: -20°F (-28°C)
Maximum: 600°F (315°C)
Seat tightness
Set pressure of 50 psig (3.45 barg): 92 percent
51 psig (3.52 barg) – 100 psig (6.8 barg): 94 percent
101 psig (6.9 barg) – Maximum Rating: 95 percent
IX. Introduction
A. 19000 MS & DA
Safety Relief Valves
Consolidated Series 19000 Portable Pressure Relief Valves
are designed to meet ASME Section VIII requirements for
fixed blowdown pressure relief valves and liquid relief valves.
They may be used for various media such as air, liquids,
process steam and hydrocarbons and may serve as either a
safety valve or a relief valve, depending upon the application.
B. 19096M-DA-BP
Safety Relief Valves
The 19000 back pressure version is only available in the .096"
(2.44 mm) orifice with an O-ring seat. It is available for steam,
liquid or gas applications and may be furnished with a plain
or screwed cap. The 19096M-DA-BP variation is furnished as
a 19096M designation with a pressure range of 50-2000 psig
(3.45-137.90 barg). The standard medium pressure valve is
limited to a minimum of 290 psig (19.99 barg) in the standard
19000 design. The designation will be used since most of the
parts are from the 19096M bill of material.
