Control Valve, Fine Control
 Brooks Model 8500 Series NRS (non-rising stem) control valves are designed specifically for extremely low-flow gas and liquid applications. Straight and 90o angle pattern models in brass or stainless steel are available. They feature a means of adjusting a sliding tapered needle which prevents sticking. These valves are particularly suitable for precise control and possess a high turns-to-lift ratio. The flow is constant for any given stem position.
