535 Manual Control Valves

The 535 Series manual control valves provide an economical means of controlling gas flow directly from a cylinder for lower pressure gases. These valves do not control pressure or back pressure in a system. If greater flow accuracy or pressure Control is required, WestAir recommends the use of an appropriate regulator (see pages 14-15 for more information). The 535 Series manual control valves are available with a variety of connections, with or without a pressure gauge.
