Crosby’s Series BP OMNI-TRIM Balanced
Piston Pressure Relief Valve
The balanced piston design offsets the effects of variable back pressure on valve set
pressure. Series BP valves can also handle applications involving high built-up back pressure.
COST REDUCTION

and vapor applications.
Maximum corrosion resistance with stainless steel trim. All 316 stainless steel, Monel, Hastelloy and NACE
optional construction are available.
Maintenance intervals extended - O-ring seal prevents service fluid from entering spring chamber.
Reduced time and administrative functions focused on environmental concerns due to superior valve seat
tightness with TFE or elastomer O-rings.
Reduced piping requirements.
No bellows to maintain or replace.
INCREASED UP-TIME & PRODUCT RETENTION
• Minimized product loss with superior seat tightness gives you more product to sell.
• Helps prevent unscheduled shut-downs as planned maintenance intervals are now possible.
Series BP OMNI-TRIM Pressure Relief Valves
Introduction
Back Pressure
FMC/Crosby Series BP is a reliable pressure relief valve
for industrial applications involving variable back pressure.
The design and options provide maximum versatility and
premium performance.
Maximum back pressure in liquid applications is 70% of
set pressure. The maximum back pressure in vapor and
gas applications is 50% of set pressure. For liquid thermal relief applications, maximum back pressure is 90% of
set pressure. Note: Maximum back pressure is 400 psig.
For pressures greater than 400 psig, consult the factory.
Effective orifice areas are 0.074 and 0.110 sq. in. (47.74
and 70.96 sq. mm). Standard materials of construction
are carbon steel cylinder; 316 stainless steel base, disc
insert, disc holder and guide; and 17-7PH stainless steel
spring.
Optional materials of construction are available for special applications or conditions involving corrosive fluids.
In addition, materials are available conforming to NACE
MR0175. Special cleanings, coatings and lubricants are
also available on application.
For applications at pressures and temperatures not listed
in this catalog, consult Crosby or your local authorized
representative or stocking service center.
ASME Code Requirements
INCREASED RELIABILITY
Series BP pressure relief valves are manufactured in accordance with requirements of ASME Boiler and Pressure Vessel Code, Section VIII and Section III.
• Fewer parts in streamlined design.
• Reliable blowdown without the need for adjustment.
CERTIFICATIONS
• Relieving capacities certified by National Board of Boiler and Pressure Vessel Inspectors. Certification
Balanced Piston Design
includes liquid and gases other than steam.
Certified Capacities
Capacity certification includes air, liquids and gases other
than steam. Relieving capacities are certified by National
Board of Boiler and Pressure Vessel Inspectors.
Seat Design
Series BP pressure relief valves are available with elastomer or TFE O-ring soft seats for optimum seat tightness and minimal maintenance. Details on O-ring materials and pressure/temperature limitations are on page 7.
All O-rings are standard commercial sizes.
Blowdown
Blowdown is the difference between the opening and
reseating pressure of a pressure relief valve expressed
as a percentage of set pressure. Series BP blowdown is
fixed and non-adjustable (typically 25% or less) on liquid,
gas and vapor applications.
Optional Connections
Series BP valves may be furnished with optional flanged
connections up to ANSI cl 1500. Standard flanged connections are lap joint stub end construction.
• Valves manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code,
Section VIII and Section III.
FMC/Crosby’s Series BP OMNI-TRIM® pressure relief valves have a simplified, single trim design with
superior application versatility. They provide overpressure protection for low and medium flow applications in refineries, chemical and petrochemical plants, power plant auxiliary systems, and pulp and paper mills.
FMC/Crosby’s Series BP OMNI-TRIM pressure relief valves provide overpressure protection on air,
gas, vapor, liquid and thermal relief service. Maximum fixed blowdown is 25% or less. Standardization of components
in the BP design provides easy assembly, durability, and less repair, maintenance and inventory costs.

Type B
Screwed Cap with Test Rod
Crosby Series BP pressure relief valves are furnished
with a screwed cap over the adjusting bolt as
standard. Optional cap types and lifting levers are
described below.
1) Standard Screwed Cap (Type A)
Where no lifting lever is required.
2) Screwed Cap with Test Rod (Type B)
Normally used to hold the pressure relief valve
closed when the system is being hydrostatically
tested.
3) Packed Lifting Lever (Type D)
For applications where periodic testing is desirable. This is a sealed design for pressure integrity.

NOTE: ASME Boiler and Pressure Vessel
Code rules require that pressure relief
valves used on air and water over

(Ref. Para. UG-136).
4) Packed Lifting Lever with Test Rod (Type E)
Same as Type D except furnished with a test rod.
Caution: Test Rods should never be tightened
more than fingertight. 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.

NOTES: 1) Maximum set pressures shown are based on carbon steel flanges. Pressure limits for 316 St. St. flanges may be lower.
Consult Crosby.
2) Flanges are supplied with a serrated face per ANSI B16.5. Other facings/standards (i.e., DIN) are also available.
3) Dimension “C” shown is for Type A cap.
For Type B cap, add 1/4 in. to “C” dimension (an additional 2 in. is required for test rod head clearance).
For Type D cap, add 5/8 in. to “C” dimension.
For Type E cap, add 7/8 in. to “C” dimension (an additional 2 in. is required for test rod head clearance).
4) Add 1.6 lbs. for Type D & E caps.
5) ANSI CL 300 supplied; however the maximum back pressure is 400 psig.

*Differential Pressure (∆ P) equals inlet pressure (set pressure
plus overpressure) at flowing conditions minus back pressure.
†See pages 8 and 10 for Minimum and Maximum Set Pressure
Limits.
Note 1: To determine capacities on gases other than air, for fluid
temperatures other than 16C, or if back pressure is specified, use
the gas and vapor sizing formula in the Crosby Engineering Handbook or the CROSBY-SIZE computer sizing program.

Air Capacities
Series BP OMNI-TRIM Valves
Set Pressures
3.45-103 barg
Capacity in standard cubic
meters of air per minute at 16C
and 10% overpressure. Valve
discharging to atmospheric
pressure.
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.
METRIC UNITS
The capacities listed in the following tables 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 7.
