The on off valve is optional if you simply screw on the tank it will work with the integral pin valve just like a bulk CO2 tank. If your using a hand pump with female foster fitting then you don't need any other whip or accessory. Just connect to the bottle's foster fitting and start pumping. Ninja bottles can be adjusted for different pressures, the standard is 850 roughly the same as CO2 at moderate temperature. They also have a SHP regulator, it ships at 1100psi and has an additional ring allowing you to adjust the final location the gage and fill nipple point when tight in the fitting.http://www.ebay.com/itm/Ninja-Aluminum-HPA-Tank-Nitro-Air-13-3000-GS-Series-SHP-Reg-1100-PSI-/170945977925?pt=LH_DefaultDomain_0&hash=item27cd2c9e45
