The ESD is a two position, two-way normally closed, manually operated ESD control valve. In the In Service
position(handle pulled), the valve has the Supply port blocked or isolated from the Exhaust port Pushing inward on the ESD Valve handle will establish a Supply-to-Exhaust flow path, rapidly depressurizing the ESD control circuit

Two-way normally closed ESD Valves are used in Emergency Shutdown (ESD) control circuits to immediately close SSV or SDV Actuators and Surface Controlled Sub-Surface Safety Valves. These controls are most commonly found in parallel ESD control circuits on many offshore platforms. They are normally installed or mounted on platform handrail ESD Stations near boat ramps and heliports

Stainless steel construction virtually eliminates corrosion freeze-up, and Sigma valves are rugged enough to help prevent accidental activation of your safety system.
