Pressure reducing valve for syphon canisters - has valve to admit high pressure charge and provides low pressure delivery

摘要

A pressure reducing valve for use with syphon cylinder is designed to provide resistance to corrosion etc. Such canisters are capable of storing 150-160 grams of liquid. The valve is inset into the end of the canister and has a threaded coupling section for connection with a high pressure supply. The high pressure fluid enter through the central bore into a high pressure chamber and moves a piston down to allow the fluid into the main chamber. When the canister is used, fluid passes through the low pressure stage to outlet.
