This is the automatic pressure relief valve for the bottom assembly on all Speidel bladder presses. This valve prevents you from over-pressurizing the bladder and rupturing it.
Replaces entire bottom valve assembly on the 180L Speidel bladder presses. Includes connection for hose inlet, drain valve and safety blow-off valve on a brass tree.
This is the threaded manifold which is used on the bottom of the press to join the water inlet, pressure relief and pressure gauge assemblies to one another and to the main center shaft of the press.
DOES NOT WORK on Speidel presses, which have a different bottom assembly.
