Co2 pressure can range between 650-1200psi. Here is the attached On/Off valve, 1/8" NPT x1" Nipple, Primary High Pressure Regulator, ASA and close nipple. Remember to turn the primary reg down to about 100psi as the Secondary reg has a maximum operating pressure of 150psi. Beer is dispensed at about 12psi and the Planet Eclipse High Pressure Regulator is a high flow reg which should have no problems feeding this.
