Regulators – use when pressure control is required for both compressed and liquefied gases.
Purge Valves – use in conjunction with the gas regulator for corrosive gases to prevent damage to equipment due to gas hydrolysis.
Control Valves – use when pressure control is not required or when a regulator is not recommended for a particular gas.
