GENERAL INFORMATION Double offset high-performance butterfly valve can be said for the butterfly valve of the usual swing-through type

formula to be a com[lately different highly efficient butterfly valve in respect of a seal performance and operational

characteristic.

Key design feature are:

- Soft seated Butterfly

- Metal seated Butterfly.

- Fire Safe Seated Butterfly

Cryogenics is the branch of physics with processes and materials at very low temperatures normally below -101deg.C

The need to handle low-temperature liquids and gases has become a commonplace requirement with fluids such as

oxygen, liquid hydrogen and nitrogen. Valves that can provide tight shut-off for isolation or modulation for control

requirements at temperature down to -196deg.C are now an essential part of today’s process plant.

2. Features of DR-Series 2-1. Double Eccentric Disc-Shaft.

Double offset disc moves entirely away from the seat at

all points in the first very few degrees of rotation. This

eliminates pivotal wear of the seat and accordingly

enables the seat to stand longer and sealing capability.

2-2. Seat Blow-out Proof

Unlikely other manufacturer's DR-Series butterfly valve has

a unique seat and seat retainer design that minimizes the

seat movement so that the seat dose not lose its elasticity

and that the retainer plate holds the seat not to be

blowing out by high delta P at the moment of opening.

2-3. Stem blowout Proof

In order to cope with the latest API 609 edition, All DR-

series butterfly features a shaft blowout proof design. The

shaft with a groove at the top side and a shaft retainer

ring protects the shaft from blowing out in case that the

shaft is cut or broken by unexpected situation

View of Blowout Proof System

2-4. Bi-Directional Service

Soft seated butterfly valve offers bi-directional service at

full pressure rating.

2-5. Dead end & Double dead end Service

All lug type DR-Series Butterfly Valve is applicable for

dead end service. Soft seated valves are eligible for the

double dead end application, which becomes an

important feature chosen for critical application.

2-6. Low Friction Bearing for extended service life

The stainless steel bearing impregnated interior with

Teflon provides high lubricity to facilitate smooth

operation. (Service temperature Max. 260℃)

Electroless nickel plated bearing is also available for high

temperature application. (Service temperature Max. 650℃)

The bearings located as close to the centerline of valve as

possible minimizes the bending stress and the deflection

of shaft.

2-7. Steam Service

BFS DR-Series Butterfly Valve offers CMTE Seat, an

exclusive selection in the seat material for the steam

service. The valve with CMTE seat provides tight shutoff

class at the steam service.

2-8 Fire Safety

All Metal seated and fire safe seated DR-Series Butterfly

Valve are designed intrinsically fire safe and certified

according to API 607, API 6FA, ISO 10497.

2-9. Universal body for different seat design

Body is machined to accommodate the different seat. Soft

seat, and fire safe seat, can be exchangeable each other

with a seat retainer on the same body. Customers can

install the metal seat on the soft seated valve by replacing

the seat with a seat retainer.

3. Seat Design 3-1. Soft Seated / DR02-Series

DR02-SeriesButterfly Valve is designed for fully applicable

within the designated pressure-temperature rating. Its

advanced trim structure enables the valve to perform bi-

directional sealing, shut-off function without assist of pipe

flange (dead end service) in both directions to offer the

easiest way in piping maintenance at field. Anti-blowout

seat & retainer design makes the valve stand at full

differential pressure of rated class rating at any position of

disc. Offering multi-selections in the seat material, DR02-

Series Valve provide a tight shutoff sealing in various

applications from low temperature to saturate steam.

- Seat Leakage Class / FCI 70-2 Class IV.

- Bi-Directional & Lower Operating Torque

Soft Seat Application Butterfly

3-2. Metal Seat of double eccentric. / DR03-Series

Inherent fire safe metal-to-metal seated valve DR03-series,

features a flexible solid metal body seat with electro-less

nickel plated disc to enhance the strength of sealing edge

of the disc. It is designed to reduce the seat movement to

keep the elasticity of metal seat long and to prevent the

seat from losing sealing capacity under high temperature

and high pressure. Like a soft seated valve, a metal

seated valve has anti-blowout design that protects the

seat under high differential pressure, which occurs when

the disc starts open and the open angle is very small.

Stellited hard face is applied for the service 350deg.C or

higher to minimize the thermal expansion of the disc,

incorporated with the inconel seat.

- Seat Leakage Class / FCI 70-2 Class V.

- Pressure Energized Sealing

- Lower Operating Torque suitable for Flow Control

Metal Seat Application Butterfly

3-3. Fire-Safe Seated / DR04-Series

DR04-Series Butterfly Valve, fully fire tested according to

API607 & 6FA, is an intrinsically fire safe valve.. DR04-

Series Valve is double seated design; the primary soft seat

backed up by the secondary metal seat. Soft seat works in

both flow directions incorporate with a secondary metal

seat, and in case of a fire the metal seat acts as a primary

seat providing leakage class IV.

Different combination of the primary and secondary seat

material provides the clients whit the extended rage of

application with DR04-Series valves. One advantage of

DR04-Series is the universal body machining that allows

the Soft or Metal seated valve for the fire safe seat

combined with a seat retainer plate.

- Seat Leakage Class / FCI 70-2 Class IV.

- Bi-Directional /Upto 10bar in non-preferred direction.

- Lower Operating Torque

relationship between the flow and the valve travel at

constant pressure drop. With cage trims, where a hole

Note

1. Torque shown do not include safety factor

2. All torque values in the table are for the wet media. If the media is dry, the torque should be 20% ∼30% greater than the

figure in the table.

3. When the dynamic torque exceeds seating / unseating torque, the dynamic torque should be taken to size an actuator.

5. Torques shown do not include safety factor.

8. Velocity Control Package 8-1. Velocity Control Plate(VCP) for Low Noise and Anti-Cavitation

Using a combination of our compact / light weight rotary qurter turn control valve and velocity control plate, we offer you

an economic solution of noise and cavitation problems in your flow / pressure control systems.

The velocity control plate is placed downstream from the control valve, and absorbs about 85% to 95% of the differential

pressure providing tremendous reduction of noise by pressure reduction device.

A single velocity control plate is more cost effective and efficient, as compared with conventional "Low Noise / Anti-

Cavitation Valves".

View of VCP Installation

8-2. A Typical Design

The resistance plate is available with one to four stages, depending on fluid and pressure drop ratio. It is custom-

engineered to suit specific condition such as flow, pressure anti-noise specification, and other requirements.

The standard design has a carbon or stainless steel body to suit an RF flange. Drain hole and water inlet for cleaning can

be provided as optional.

Multi-Hole 1-Stage Multi-Hole 2-Stage with Drain Multi-Hole 4-Stage

8-3. Typical Application

- Pump start-up by-pass line.

- Downstream of regulator on reduction device in gas line

- Downstream of steam pressure reduction valve

- Vent or flare systems on gas lines.
