NF Speed Control Valves

NF 1, 2, 3

The NF Flow Controls are designed to be wafer mounted between the Flow Line Controls Series 50 solenoid valve and Series 20/21 pneumatic actuator. The NF adjustable needle valves restrict air flow rate and actuator speed.

NF1: Unidirectional, One-Adjustment

The NF1 is a unidirectional needle valve used to adjust closing or opening speed. Only one direction of rotation can be adjusted. It can be used with DOUBLE ACTING or SPRING RETURN actuators.

NF2: Double Unidirectional, Two-Adjustments

The NF2 is a double unidirectional needle valve for DOUBLE ACTING actuators. It is used to adjust the closing and opening speeds.

NF3: Double unidirectional, Two-Adjustments

The NF3 is a double unidirectional needle valve for SPRING RETURN actuators. It is used to adjust the closing and opening speeds.
