The charted seating and unseating torques are the sum of all friction and includes opening and closing of the disc against the indicated pressure differential for normal service. The relationship between values are linear, therefore you can interpolate between nominated values. Increase plant level optimization, training, and planning aligned to your business goals.
Available with PTFE lining for light corrosive services and rubber lining for light abrasive services.
General Applications Technical Data Suited to many applications where tight shut-off is required, such as: Secondary shaft seal by oversizing the shaftdiameter in relation to the shaft hole in the seat. Weight may vary depending on trim materials used. F89 Pneumatic Quarter Turn Actuator. Looking for performance and keeystone from your Butterfly Valves?

Keystone Butterfly Valves with a reliable and robust construction, higher cycle life with lower total cost of ownership. With a tradition of more than 70 years, Keystone built its reputation on providing industrial process butterfly valves known for their reliability, long service life, and reduced operating costs.
Triple function, resilient dovetail seat isolates body and stem from line media, provides drop-tight shut-off of line media at full-rated pressure and permits convenient and economical replacement in the field. The seat and disc are the only two valve partsin contact with the medium.
The accurate machining of all valve components, and the combination of safety precautions butterfly the shaft area provide a drop-tight seatsealing and a positive gastight shut-off through the shaft area to atmosphere.
