Parker Veriflo offers the non-altitude sensitive, excess flow shut-off valve designed to operate with a wide range of inlet pressures. The capability of operating from 10 to 3500 psig allows it to be used either between a high pressure source at the inlet to the pressure regulator, or in the low pressure delivery line to a process. In both applications, this control valve will automatically shut off the delivery of gas if the flow exceeds a preset limit.
