800 Series Control Valves
You'll most fully appreciate the extra built-in quality and
reliability of a Nelson control valve when it performs under the
most demanding operating conditions. As a hydraulically
operated sleeve type valve, the 800 Series is designed for
versatility. The basic body can be equipped with several
different control packages in various combinations for
controlling pressure and flow in large piping systems. It's also
engineered for extremely high efficiency, resulting in low friction
loss and high capacity. It's light weight and compact for ease of
shipping, handling and service. Options include: basic control,
manual control, automatic control, pressure control, rate-of-flow
control, combination, and special purpose (check valve, sleeve
exhaust, special on/off, or special function).
