In accordance with ASME code, a pressure switch, pressure gauge, or vent must be connected to the space between the rupture disc and the connected pressure relief valve. Hansen pressure switches meet the ASME code requirement when installed properly. The pressure switches provide an electrical indication that a rupture disc has burst and that a relief valve has discharged. The pressure relief valve will reseat after discharging while the
rupture disc remains open. The pressure switch will maintain the signal until a new rupture disc is installed and the pressure is reduced to zero.

Hansen Technologies continues to lead the industrial refrigeration industry with innovative products, excellent customer service and outstanding technical support. We offer an extensive line of components for industrial refrigeration
systems including sealed motor valves, control valves, shut-off valves, pressure-relief valves, refrigerant pumps, air purgers, defrost controls, and liquid level controls. For more information, contact
