Description

This line mounted restrictor throttles and limits the flow from  B to A; it has an adjustable built-in restriction which can be  tuned by rotating the external pinecone-type knurled sleeve  from fully closed to fully open. Flow will increase by rotating  the sleeve toward (+) direction. Once the desired adjustment  is achieved, the sleeve can be locked by tightening the knurled  ring nut (H) in order to prevent inadvertent changes or motion  due to line vibrations. The maximum adjustment stroke is  identified as K and, for different valve sizes, is shown by the  specific table. This valve is a variable adjustable restriction, nonpressure-compensated: the actual flow through the valve will  be determined by the pressure differential available between  inlet B and outlet A, and also by the oil viscosity. Unrestricted  reverse flow from A to B is permitted through a poppet type  check valve, with cracking pressure 0,5 bar (7 psi) regardless  of valve adjustment. The valve is available in different sizes for  different flow ranges, as specified by the tables of the Technical  data and Dimensions. Minor leakage “B-A” can be expected with valve fully closed Free reverse flow “A-B” is always allowed through the  incorporated poppet check valve with 0.5 bar cracking  pressure.
