Fisher™ V250 Control Valve

The Design V250 Hi-Ball rotary control valve is designed for heavy-duty throttling and on-off applications. Depending on size, this valve installs between two CL600 or CL900 pipeline flanges. The Design V250 valve is available with a single ball seal, flow ring, or dual-seal construction. Single-seal constructions are used in tight shutoff applications; the flow ring construction can satisfy higher temperature requirements. The dual-seal construction, with a seal in the inlet and outlet openings, is used in bidirectional flow-shutoff applications. The Design V250 Hi-Ball valve is typically used for throttling and controlled flow applications in gas transmission lines, gas distribution, or liquid pipelines.
