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.
