BFE manufactures the most complete line of quality ball valves, and can provide the exact ball valves and actuators to meet the most demanding application requirements. Our Floating Ball Valves are available in an extensive range of designs, materials, sizes and pressure classes and are in full conformance with ANSI, API and NACE specifications. All ball valves are designed in accordance with ASME B16.34 and where applicable with API 6D or BS EN ISO 17292.

The BFE family of floating ball valves provides positive shut-off of fluids and gases under extreme service conditions.

BFE uses only high-quality materials inspected & tested to International Standards and utlizesadvanced manufacturing technology with special emphasis on safety, quality, and long service life of our products, to ensure that our clients receive the “best in class” products available from us at a competitive price and delivered on time.

The forging material can ensure the best rigidity and strength under maximum rated operation pressure without inherent flaw of cast. Other properties found in forging include greater impact resistance, resistance to fatigue cracking, particularly when cycling at either high or cryogenic temperature. Overdesigned wall thickness and adaptation of high strength tie bolts are convenient for valve maintenance and sufficient to bear the stress of pipe. The internal parts of valve are carefully designed and selected to ensure reliability under all kinds of work condition.

Since a variety of materials are available, BFE valves can be used with various fluids and gases including petroleum based oils and some water glycols.

The design of BFE ball valves is based on the “floating ball” principle which allows the ball to turn freely between the ball seals.

A positive seal is attained by fluid pressure acting on the upstream surface of the ball and producing a constant uniform contact between the downstream ball seal and the ball. The ball is operated by a sealed spindle with a projecting square end to which the control lever or optional actuator is attached. Ball valves are intended to be used as on/off flow control devices and are not to be used to throttle fluid flow. The valves should always be either fully open or closed.

BFE Floating Ball Valve design is developed using the latest software based analysis tools.

At the design stage, all projects are analysed using 3D solid modelling tools. Benefits include reduction of development time and cost, improved product quality, and ability to solve field problems for customers. Product flexibility and accuracy is assured.

Finite Element Analysis (FEA) is a very important step at the development stage to ensure the best possible performance requirements. Valves operational problems, pressure/temperature- related deformations and flow-related forces within a valve can be evaluated.

BFE uses the FEA for predicting failure due to unknown stresses by showing problem areas in a material and allowing designers to see all of the theoretical stresses within. This method of product design and testing is far superior to the manufacturing costs which would accrue if each sample was actually built and tested.

During any analysis project, it is the responsibility of the BFE analyst to verify that analysis results conform to the physics of the problem under study. Understanding the response of a structure or manufactured product allows effective design decisions to be made in developing structures and products that are functional, meet all engineering requirements, and can be manufactured and assembled.

Computational Fluid Dynamics (CFD) is used to simulate operating flow conditions. Evaluation of Valve CV coefficient and convective heat transfer coefficient takes place at the design stage.


FIRE-SAFE TEST APPROVED: BFE floating ball valves are designed in accordance with API 607 & API SPEC 6FA. When non-metal seats are destroyed in a fire, the upstream medium pressure push the ball into the downstream metal seat lip to cut off the line fluid and prevent internal leakage due to a secondary metal-to-metal seals. When the first soft seal is damaged, body/gland/stem gasket can reach sealing function and prevent external fluid leakage.

DOUBLE BODY GASKET: All BFE floating ball valves are equipped with two body gasket. The first body gasket is in soft material and the second in graphite (if not otherwise required), this combination assures the best seal characteristic in whatever corrosive service as well give fire safe design.

Antic-Static Device: In order to prevent static electricity which may light the fluid, static-conduction spring is set between the stem and the ball.

ANTI BLOW-OUT PROOF STEM: The stem is designed with integral T-Type shoulder to provide blow-out proof effectively. The design assures that the stem cannot be blown out of the body in the case of the gland being removed while the valve is under pressure.

CONTROLLED STEM & STUFFING BOX FINISH: Stem and stuffing box finish machining is a key point of control. The stem is made by cold rolling and stem surface finish is controlled by Ra=0.4, which can reduce friction for stem moving and ensure the seal. The stuffing box surface is controlled within Ra=1.6 for better sealing performance.

SOLID BALL: The solid ball used by BFE provides straight through flow and real full-port performance characteristics. Hollow ball or cored cavity ball are not used for BFE products.

LONGEVITY OF LIFE: Special consideration was devoted to the attainment of enhanced life and operation of our valve throughout design, development, testing and manufacturing stages. Valve designs combined with the selection of advanced materials are such that long periods of inactivity should not affect the operations of efficiency.

LOW TORQUE OUTPUT: Seat designs, stem-bearing system and stem seal arrangements ensure consistent minimal torque values.

FLOW CAPACITY: Valve design allows for high flow capacity in liquid or gas services regardless of whether the media is clean or dirty. Full port valves allow for pigging and ensure maximum flow capacity.

FIELD REPARAIBLE: Simple user friendly design allows for quick and easy part replacement requiring minimal «Down Time».

ISO FLANGE INTEGRATED IN THE BODY DESIGN: ISO 5211 mounting always integrated in the forged body as standard design.

INSPECTION AND TESTING: Every valve is subjected on routine base to different non-destructive testing, like the dye penetrant test on butt weld ends, on all hard faced and cladding areas. Non-destructive tests are also carried out on the critical areas as defined by ANSI B.16.34.

Optional examinations like: Radiographic Magnetic particles Ultrasonic Helium leak test Personal performing NDT are trained and qualified to EN 473/ ASNT-SNT-TC-1A.

Every valve is subject to a pressure test in accordance with the standard API 598 or BS 6755 Part.1. The rated pressure for the applicable pressure class is in accordance with ANSI B.16.34 / EN 12516-1-2.

MARKING AND IDENTIFICATION: Each valve is identified on proper name plate and on valve body as required by MSS- SP 25, B 16.34 Name plate carries all information on rating, size, valve body and trim material, customer tags. On body, marking includes material designations (per ASTM) and heat code and of course the trade mark.
