TFW PRODUCTS

Body Size: 4 inches (100 mm)
Body Material: Ductile iron, stainless steel, aluminum,
Disc: Usually stainless steel
Seat: Rubber, EPDM, PTFE,
Stem: Stainless steel
Operating Temperature Range: Depends on materials, but usually -20°F to 250°F (-29°C to 121°C)
Pressure Range: Can handle pressures up to 150-300 psi depending on materials and design
Actuation: Manual lever, gear operator, pneumatic actuator, electric actuator
End Connection: Flanged, wafer, lug style
Flow Characteristics: Butterfly valves provide relatively high capacity and have quick open/close ability, but do not provide tight shutoff compared to ball or gate valves
Typical Applications: Isolation, throttling, control in water, air, gas, steam and other non-viscous fluid applications
