The Fisher V250 control valve is a heavy-duty, flangeless throttling ball valve often used to control flow in gas transmission lines, gas distribution, and liquid pipelines.
Available with a single ball seal, flow ring, or dual-seal construction.
Tapered-polygon ball-to-shaft connection and clamped splined actuator connection remove lost motion or deadband from the drive train.
Reduced ball port design provides a modified equal percentage flow characteristic and an excellent response characteristic.

Pressure-balanced drive shaft design with PTFE-lined bearings and pressure-assisted shaft sealing arrangement provides for a long life of reliable service.
