Description

A Variable Flow restrictor with Positive Shut-Off and Free reverse Flow

A wide range of flow adjustment in the controlled flow direction is possible because of the fine thread and tapered needle. A spring biased ball check allows full flow in the opposite direction. Unwanted changes in adjustment are prevented by a lock nut.

Features and Benefits
  • A wide range of flow adjustability
  • Lock nut to maintain flow setting
  • Positive shut-off
  • Eliminates need for extra pipe nipple
