Avoid Dangerous Overpressures

May 13, 2011
Billed as an industry first, the OPD Stemsaver is a high-integrity pressure regulator for the pneumatic control systems that are widely used for valve actuation in the oil, gas and other processing industries.

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.
