Brooks NRS Flow Co
ntrol valves are designed for gas and liquid applications with the lowest flow rates. Available in stainless steel straight and 90° Angle. This series is ideal for rotor flowmeters with needle valves. The needle valve flow can be co
ntrolled by adjusting the sliding co
nical needle. This prevents adhesion caused by foreign objects in the fluid. These flow co
ntrol valves are especially suited for precise co
ntrol requirements and have a high turn to lift ratio. The flow rate is co
nstant for any given stem position.
Six different taper needles offer a wide range of flow options. Replace the needle and orificket without removing the valve body from the line (use two different orifickets, * for needle size 1-3 and * for size 4-6).
