Alis Valves is a leading manufacturer of High Pressure Emergency Shut Down Valves (ESDV) designed for critical isolation in high-pressure pipelines and hazardous industrial environments. These valves provide rapid shut-off during emergencies such as pressure surges, leakage, or fire, ensuring maximum safety and protection of equipment and personnel. Engineered with robust construction and fail-safe actuation systems, they are widely used in oil & gas, petrochemical, refinery, and power industries.
Product Specifications and Overview
ALIS Valves offers High Pressure Emergency Shut Down Valves for industrial applications requiring reliable isolation under high-pressure operating conditions. These valves are designed to rapidly stop the flow of liquids or gases when an emergency signal is received from a compatible safety control system. Built to meet specified pressure and service requirements, they use suitable valve body materials, sealing components and actuator configurations to support dependable shut-off in demanding process environments. Depending on the design, fail-safe operation can move the valve to a predetermined safe position if the control air or power supply is lost.
High Pressure Emergency Shut Down Valves are suitable for compatible applications in oil and gas facilities, refineries, petrochemical plants, gas processing units and high-pressure pipeline systems. They are commonly integrated into emergency shutdown systems to isolate process equipment, pipelines and vessels during abnormal operating conditions. Important selection factors include maximum operating pressure, temperature, process media, valve size, required shut-off time, pressure rating, body and seal materials, actuator type and fail-safe requirements. Selecting the appropriate valve configuration helps support reliable emergency isolation, equipment protection and safe operation under the intended working conditions.

Frequently Ask Questions
A High Pressure Emergency Shut Down Valve (ESDV) is an automated isolation valve designed to rapidly shut off high-pressure process flow during emergency conditions such as leakage, pressure surges, fire or equipment failure.
A spring-return actuator can provide a predetermined fail position when the operating air or control energy is lost. This is useful for emergency isolation systems.
The primary purpose is to quickly isolate a hazardous or high-pressure section of a process system to help limit the release of process media and protect equipment and personnel.
