Certified Valve Technology for Safe and Effective Oil Refining Operations

Downstream refining plants rely on Emerson’s extensive selection of ASCO solenoid valves and valve assemblies to maintain process uptime. Our time-tested technology is ideal for controlled operations to protect against unintended shutdowns while maintaining reliable controlled shutdowns. We offer refineries a full solution for actuator control: filter regulator, solenoid valves, accessory valves and switch boxes. ASCO pilot valves, manual reset valves, and redundant systems are an integral part of the final control element for any Safety Instrumented System.
