LVS Products: LV 690

The LV690 series rotary control valve utilizes a heavy duty construction which is suitable for both modulating service and on-off applications. The flangeless valve body is typically installed in gas transmission or liquid pipelines and is designed to be installed between CL600 or CL900 pipeline flanges. The valve is available with either a single or dual ball seal. The single seal offering provides tight shutoff in the forward flow direction while the dual seal offering combines tight shutoff with bidirectional flow capability.
