Featuring “Next Generation” Pratt Butterfly Valves
Blowout proof stem
Blowout proof stem meets all API 609 requirements. Our unique design also creates a secondary stem journal seal preventing leakage to atmosphere.
TOP FLANGE
Top flange conforms to ISO 5211 and KV industrial standard allowing a universal mounting pad for automation requirements which is suitable for most actuators in the market.
A full length Nylatron® bushing
A full length Nylatron® bushing reduces stem journal friction and reduces torque.
Pratt utilizes 2 internally driven shafts
Creating a strong drive connection and allowing for a thin profile disc creating high Cv's.
Thin profile, high tensile strength disc
Maximizes Cv's and allows for 230psi pressure rating.
Pratt’s unique seat design
Utilizes 3 tongue and groove connection points to the valve body. Seats remain secure and stable even under high dead-end pressure. The center tongue not only locks the seat in place, but allows rubber material to flow into the center body groove when cycling the valve, drastically reducing the operating torque.
Pratt’s BF Series bottom cap
Provides lower stem retention and also creates a secondary stem journal seal preventing external leakage to atmosphere.2"–12" lower shafts ride on a precision wear guide reducing shaft drag.
Featured Products
BF1 Bare Stem
BF1 Bare Stem
WAFER STYLE VALVE
- Installation: Clamped between two pipe flanges with stud bolts and nuts.
- Pressure: For use in low to moderate pressure applications, less than 230 psig, such as water systems, chemical and food processing.
- Maintenance: Easily disassembled for seat replacement.
- Suitability: Best for applications where space and cost are critical.
BF1 with Accessories
BF1 with Accessories
Customize your valve for specific process needs. Choose from any combination of the following accessories:
ACTUATOR
- DOUBLE ACTING
- SPRING RETURN
SOLENOID
- 3 / 4 Way
- 120 VAC and 24 VDC
- NEMA 4 and 7
LIMIT SWITCH
BF1 with Solenoid
BF1 with Solenoid
A solenoid is needed for a butterfly valve actuator to provide automated on/off control of the fluid flow. The solenoid acts as an electro-mechanical switch, using an electromagnetic coil to control the actuator, which in turn opens or closes the valve without manual intervention. This allows for quick response times and integration with automated systems like PLCs and sensors.
BF2 BARE STEM
BF2 BARE STEM
LUG STYLE VALVE
- Installation: Has threaded lugs for individual cap screws to attach to each flange, allowing it to be used in dead-end service.
- Pressure: For use in low to moderate pressure applications, less than 230 psig, such as water systems, chemical and food processing with a more robust construction than the wafer style.
- Maintenance: Easily disassembled for seat replacement.
- Suitability: Ideal for situations requiring maintenance without removing the valve.
BF2 with GEAR OPERATOR
BF2 with GEAR OPERATOR
A gear operator provides higher torque for large-diameter or high-pressure applications, making the valve easier to open and close. The gear mechanism multiplies the input force, which reduces the physical effort required by the operator and allows for more precise control of the valve's position. This also enhances safety by enabling slow, controlled operation to prevent water hammer effects and locking the valve securely in place.
BF2 with Lever Handle
BF2 with Lever Handle
A lever handle is used in smaller valves (<10”) for quick, simple, and visual operation, as the handle allows the internal disc to be rotated 0-90 degrees to open or close the valve, or placed in an intermediate position with a 10-position notch plate. The lever position provides a clear indicator of the valve's open or closed status.
