Brief Description
Install the valve between the pump outlet as close as possible, and any shut-off device in the discharge line. The preferable mounting position is vertical with the adjusting cap at the top.
By-passes the system fluid to porevent instrument or sensitive gauge in the system from excess pressure.
When the inlet pressure overcomes the set spring pressure on th poppet, the poppet lifts off the valve seat,allowing flow to pbypass and thereby balance the system pressure.
