Valves are technically valves fittings, but are usually discussed as a separate category.

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.
