Description
Design V250 Hi-Ballr valve is a flangeless rotary
control valve used for high pressure, throttling or
on-off control of liquid or gas applications (see figure
1). These valves operate on a rotary motion input
through a splined valve-shaft/actuator-shaft
connection for use with power or manual handwheel
actuators. The single seal, dual seal, and flow ring
constructions are covered in this instruction manual.
