Samson Gas Regulator 4708 High Pressure Large Flow Air Pressure Regulator
The Type 4708-45 Supply Pressure Regulator reduces and controls the maximum pressure of 12 bar (180 psi) in a compressed air network to the pressure adjusted at the set point adjuster. The device is designed to operate under exactly defined conditions (e.g. operating pressure, temperature). Therefore, operators must ensure that the supply pressure regulator is only used in applications where the operating conditions correspond to the technical data. In case operators intend to use the supply pressure regulators in other applications or conditions than specified, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the device for its intended purpose or for damage caused by external forces or any other external factors.
