to control the 7/32-inch (5.5 mm) nominal stroke valve.
·
Maintenance free actuator with reversible motor.
·
Selector plug on actuator permits selection of linear or equal percentage flow
characteristics.
·
Reduced seat diameter produces reduced C
·
0 to 10 Vdc or 0 to 1000 ohms signal input.
·
Position output signal 0 to 10 Vdc.
·
Available with union or sweat end connections (1/2-inch and 3/4-inch).
·
Double O-ring packing with Teflon® wiper.
·
Manual override knob with indication of stroke allows for repositioning of the valve
in power-off conditions (SQS65U only).
·
