Dwyer Series BV2FH User manual

Brand: Dwyer

Model: Series BV2FH

Type: User manual

Dwyer Series BV2FH is a two-piece stainless steel flange ball valve designed for industrial applications. Its ANSI 150# flanged ends simplify installation, while its RTFE seats and seals ensure extended service life. With an ISO 5211 mounting pad, it readily accepts pneumatic and electric actuators for automated operation. It handles various compatible liquids and gases, making it suitable for a wide range of process control systems.

Bulletin V-BV2FH

The Series BV2FH Two-Piece Stainless Steel Flange Ball Valve is

designed to meet ANSI B16.34 flange standards and features ANSI 150#

flanged ends for easy installation. The valve features a stem design

providing additional protection against blow outs and RTFE seats and

seals for extended life. An ISO 5211 mounting pad accepts direct

mounting of pneumatic and electric actuators. All sizes allow for

maximum flow rates with minimal pressure drops. The Series BV2FH

body, ends, and ball have increased performance from the 316 SS

construction.

OPERATIONS

Manual Operations-To open or close the valve, turn the handle 90° (1/4

turn). Valve in OPEN position: the handle is parallel (in line) with the valve

pipeline. Valve in CLOSED position: the handle is perpendicular

(crossed) with the valve or pipeline.

Automated Operation-Valves with actuators should be checked for

stem alignment. Most applications are direct mount to the actuator,

greatly reducing any sideload or increased torque. Make sure that all

insert adapters are properly placed on the valve stem and fully engaged

in the actuator.

INSTALLATION

General Information for On-Site Installation-The valve may be fitted in

any position in the pipeline. For automated operation, W.E. Anderson

recommends that the valve and actuator be installed vertically in case of

valve leakage, although this is not necessary for proper operation of the

valve. Prior to installation, inspect valve and pipe ends to make sure they

are free from debris. Materials trapped inside the valve can cause

damage to the seats and result in leakage. The flow may be in either

direction of the valve. It is recommended to use expanded PTFE or

rubber gasket on a flat-faced flange. Flange bolts should be used and

evenly torqued using a torque wrench.

MAINTENANCE

This valve is designed for applications requiring ease of cleaning and

maintenance.

To disassemble:

First, make sure the valve is isolated from both process media and

pressure. Rotate the valve several times to relieve any pressure

contained in the ball cavity. Then loosen the four bolts and separate the

two pieces.

To re-assemble:

Tighten all bolts in a “star” pattern to ensure even compression. See Bolt

Torques table for proper assembly bolt torque. Rotate the valve handle

several times to check for free travel.

WARRANTY

The Series BV2FH warranties from defects in materials and

workmanship are covered for (1) year from the date of purchase. In the

unlikely event the valve should fail, the unit can be returned to the factory

for warranty repair if the warranty period has not expired. Be sure to

include a brief description of the problem plus any relevant application

notes. Contact our customer service department for an RGA number and

to set up the return.
