ESD-Emergency shutdown valve

The ONERO ESDV family of products provide:
• Immediate control of overpressure, high liquid level or both with integrated design
• Pneumatically or hydraulically operated
• Upstream installation flexibility due to connective design

The emergency shutdown function is always performed by an emergency shut down valve. An emergency shut down valve (also referred to as ESDV or ESD) is an actuated valve designed to stop the flow of a hazardous fluid upon the detection of a dangerous event. This provides protection against possible harm to plant team, equipment or the environment. ESDV form part of a Safety instrumented system. The process of providing automated safety protection upon the detection of a hazardous event is called Functional Safety which ONERO has pioneered for the last three decades.

ONERO offers a wide family of shutdown valves, actuators and positioners are engineered to prevent catastrophic incidents when deviations in critical processes occur. Our product lines cover a breadth of SIL, ANSI and DIN class ratings, providing solutions reliable enough to handle the most critical oil & gas applications, whether onshore, offshore or processing. Shutdown valves are primarily associated with the petroleum industry although other industries also require this type of protection system (power generation, chemical industry…)
