Materials in bold indicate variation from standard.
Crosby Series 800, Series 900 OMNI-TRIM® and
Series BP pressure relief valves are furnished
with a threaded cap over the adjusting bolt
as a standard. Optional cap types and lifting
levers are:
1.
2.
Standard threaded cap (Type A)
Where no lifting lever is required.
Threaded cap with test rod (Type B)
Normally used to hold the pressure relief
valve closed when the system is being
tested hydrostatically.
3. Packed lifting lever (Type D)
For applications where periodic testing
is desirable. This is a sealed design for
pressure integrity.
4. Packed lifting lever with test rod (Type E).
Same as Type D except furnished with a
test rod.
Note
ASME Boiler and Pressure Vessel Code rules require
that a lifting lever must be supplied with the valve
when the service is (1).ir, (2) water at the valve inlet
that exceeds 140°F (60°C) excluding over pressure or
relief events or (3) steam.
Caution
Test rods should never be tightened more than
finger tight. Overtightening may damage internal
parts. Moreover, a test rod should never be kept
on the valve during operation of the equipment.
During normal operation the test rod is replaced
with cap plug and O-ring to maintain tightness
on the discharge side.

1. To determine capacities on gases other than air, or for fluid temperatures other than 60°F (16°C), use the
gas and vapor sizing formula in the Crosby Engineering Handbook.
Note: for air capacities, USCS units are exact equivalents of imperial units.
The capacities listed in the table above are based on discharging to atmospheric pressure. For
applications involving back pressure these capacities must be multiplied by the back pressure
correction factor determined from the applicable curve shown on page 40.
Capacity in standard cubic feet per minute of air at 60°F and 10% overpressure. Valve
discharging to atmospheric pressure. (Capacity in standard cubic meters of air per minute at

Notes
1.Differential pressure (ΔP) equals inlet pressure (set pressure plus overpressure) at flowing conditions
minus back pressure.
2. See pages 23 and 24 for minimum and maximum set pressure limits.
Note: USCS units for water and liquids are U.S. gallons per minute (1 U.S. gallon equals
0.833 imperial gallon).
The capacities listed in the table above are based on discharging to atmospheric pressure. For
applications involving back pressure these capacities must be multiplied by the back pressure
correction factor determined from the applicable curve shown on page 40.
Capacity in U.S. gallons per minute of water at 70°F and 10% overpressure. Capacities certified
by the National Board of Boiler and Pressure Vessel Inspectors and in accordance with the
ASME Boiler and Pressure Vessel Code, Section VIII. (Capacity in liters per minute of water at
21°C and 10% overpressure.)
Capacities certified by the National Board of Boiler and Pressure Vessel Inspectors and in
accordance with the ASME Boiler and Pressure Vessel Code, Section VIII.
