The device is designed to guard against failure of the filter-regulator that controls compressed air system pressure, by providing dual-redundant over-pressure protection. It ensures that downstream actuators for controlling process valves cannot be accidentally exposed to dangerous over-pressures that could shear a valve stem or cause other damage. The OPD Stemsaver provides a dual-redundant pressure regulation facility with one diaphragm regulator, coupled to a spring-tensioned poppet valve. These two different regulation mechanisms provides additional reliability. The device can be set to regulate pressure in the 4-8 bar (58-116 PSI) range, and is supplied as a single unit, fabricated in 316 stainless steel.
