Use this Spunding Valve from Keg King to set the desired pressure in your pressure fermenter. Simply attached to the fermenter gas disconnect and set the pressure using the adjustable valve. When the pressure reaches the set PSI/Bar, the valve will relieve the pressure out of the fermenter.
Can be used for relieving pressure in unitanks or when transferring to kegs or other vessels.
The gauge displays up to 15 PSI. Constructed of brass with steel spring to control the internal poppet.
