56H Series Industrial Cylinder Regulator

Single stage, six-port cylinder regulator for general industrial applications
56H5311-01-580 shown

The 56H Series medium heavy-duty welding, heating, and cutting regulator provides primary pressure control of industrial gas cylinders with outlet pressures up to 500 PSIG (35 BAR). The heavy-duty, brass barstock body provides high durability, while the encapsulated seat design provides steady and reliable pressure control with an extended component lifecycle. Combined with a wide range of delivery pressures and configurations, the 56H Series regulator is a flexible and durable choice for cylinder and pipeline applications.
