Ball Valves

Floating • Trunnion Bolted Body • Trunnion Fully Welded • Top Entry

Combines the strenght of its components with a dependable and compact design.

Babcock ball valves satisfy a wide range of ASME, ANSI and API standards. Available in cast steel and forged steel, with various trims, they may be specified in sizes from 1/4″ to 60″, and pressure classes of 150 through 2500.
Engineered for heavy duty, maintenance-free performance, the BV ball valve is commonly selected for a number of demanding applications, being considered one of the most trusted valves in the petroleum and chemical process industries.



Product Range

Floating Ball Valves

Code BFI

Type: Floating Ball Side Entry 
Body: One Piece
Sizes: 1/2″- 3″
ANSI Class: 150-900

A simple design with a good sealing performance for low and middle pressure applications.

Floating ball valves uses natural line pressure to press and seal the ball against the downstream seat.
To avoid the deformation of sealing ring due the workloads it withstands, our designs increase the contact area between the ball and the sealing ring, reducing the sealing pressure. 



Code BFR

Type: Floating Ball Side Entry
Body: Threaded & Sealed
Sizes: 1/2″- 12″
ANSI Class: 150-900

Trunnion Mounted

Trunnion design for dependable low torque operation.

Babcock Trunnion ball valves have floating seats that move with the medium pressure to tight the ball and seal ring to ensure sealing reliability.
Bearings mounted in top shaft and bottom shaft, reduces considerably operation torque. They are mainly used in valves with high pressure and big sizes.
To decrease the operation torque and increase the reliability of the sealing, Babcock ball valves are supplyed with two greasing fittings into both, the upstream and the downstream seat pockets.

Body: Bolted
Sizes: 2″- 60″
ANSI Class: 150-1500


Code BGS

Type: Trunnion-Mounted
Body: Welded Body
Sizes: 2″- 60″
ANSI Class: 150-900


Code BGT

Type: Trunnion-Mounted Top Entry
Body: Bolted Body
Sizes: 2″- 60″
ANSI Class: 150-1500


Wide selection seat/seal trims
A wide variety of trims are available to match each valve to its aplication, including metal to metal trims.

Protected seats for long life
The protected seat design features a deep pocket with a protective lip. This design prevents cold flow of the seat into the line. This results in extended seat life over conventional designs.

Large diameter trunnion
Provides smooth, easy operation and extended bearing life. The trunnion bearings are stainless steel with heavy duty PTFE coated.

Actuator mounting brackets
Available as options for users who prefer to install their own actuators. We recommend that buyers specify factory- installed actuators to assure reliable, long life performance.

Bidirectional sealing
Babcock trunnion valves are equipped with pressure-actuated seats offering true bidirectional sealing performance.

Automatic body pressure relief
The pressure actuated seat construction assures positive relief of excess pressure. If the body pressure exceeds the line pressure and seat pre-load pressure, the seat(s) will automatically back off to relieve the excess pressure.

TFM insert
The seat assembly consists of an outer metal seat ring with a TFM insert. The TFM insert locates into a groove in the metal ring. A spring assembly behind the seat loads the seat against the ball and prevents leakage from behind the seat. This efficient seat design provides positive shutoff.

Double block and bleed
The pressure actuated seats of Babcock’s trunnion valves provide a positive up and downstream seal under all conditions. When used for block and bleed, this feature lets the valve to take the place of two valves, allowing the operator to check the up and downstream sealing by installing a pressure releasing tool to bleed body pressure.

Easy to maintain
Babcock valves can be completely disassembled in the field for replacements of seats or a complete overhaul. Seats can be replaced quickly without the need for special tools.

Positive stem retention
Babcock trunnion mounted ball valves are manufactured with true anti blow out stem. The stem is inserted from whitin the valve body and is positively retained whitin the body cavity. This method of stem retention eliminates the need for external locking pins devices, which may be subjected to inadvert removal and the subsequent risks.

Adjustable packing
The stem packing material is graphite. The unique design of the BV stem packing assembly allow full maintainability of the packing material and replacement of FPM o-rings while the valve is in line and in service. This is achiebved by the security of a secondary stem seal located below the packing and upper lantern ring.

Babcock valves are suitable for operation by any type of pneumatic, electric, or hydraulic actuators. We offer factory-mounted valve-actuator packages with single source efficiency, responsibility and warranty.
