Restriction Orifice Unions

Available in carbon steel or stainless steel designs, O'Keefe Controls Co. restriction orifice unions are used widely in liquid or gas piping systems to meter flow rate within a wide range of pressure and temperature variables. The devices are used to set flow rates for compressed air, water, steam, hydraulic fluids, gases, liquid chemicals and coolants. An easily replaceable orifice metering plate within the device assembly makes it easier to change flow rates. The all metal assembly is capable of a wide range of pressure and temperature variables.
