Engineered for oil and gas wellhead safety, the ACQD Self-Actuating Emergency Shut-off Valve provides smart, automatic rapid shutoff during overpressure, under-pressure, or extreme temperature events. It enables precise configuration of high/low-pressure and overtemperature trip points, ensuring reliable protection tailored to specific operational requirements. The valve supports manual operation and enables electric and remote on/off control under low-power conditions. It features a built-in self-diagnostic system that continuously monitors key parameters such as valve position, component health, power status, and temperature. With the Modbus RTU communication protocol, it allows seamless data exchange with external systems.
