Male-To-Female Flow Control, Needle And Check Valves
  • Eliminates Need for Extra Pipe Nipple

FLOW CONTROL
A spring biased ball provides full flow in one direction; a tapered needle provides a wide range of adjustment of flow in the controlled direction. A locknut prevents unwanted changes in adjustment. A knurled knob is standard; a tamperproof adjustment key is available.

NEEDLE
A wide range of flow adjustment is possible because of the fine thread, tapered needle. Unwanted changes in adjustment are prevented by a locknut. A knurled knob is standard; a tamperproof adjustment key is available.

CHECK
A slight pressure differential fully opens or closes the ball or poppet check valve. This valve is available with either ball check or bubble-tight poppet check.
