Product Description


Keystone Figure 990 Butterfly Valve with Powered Actuator

The Keystone Figure 990 is a split body, thin disc resilient seated butterfly valve complete with powered actuator,
configurable by power source, size, function and more.

Wafer and lug are used when sanitary service or corrosion resistance is required. Heavy duty applications include textile, food and beverage, pharmaceutical, pulp and paper, mining and power industries. Available with PTFE lining for light corrosive services and rubber lining for light abrasive services.

Application Example:
FONGS, THIES, THEN Dyeing Machine

Features & Benefits:
One-piece, thin profile, 316 Stainless steel disc/stem provides minimum obstruction to flow, resulting in highest Cv, lowest pressure drops and best control characteristics. Also available with PTFE, NBR or EPDM molded disc.
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.
Heavy duty, corrosion resistant top bushing provides upper stem support, absorbs actuator side loading and extends valve cycle life.
Bi-directional, self-adjusting double V-cup stem seals prevent external contaminants from entering the valve.
Split body design enables easy field replacement of seat and disc/stem and permits direct mounting of Keystone actuators without the use of couplings or brackets.

Sizes:
Wafer style: 1" to 20"
Lug style: 2" to 20"
