High-Performance Cast Iron Emergency Shut-Off Valve for Fuel Dispensers

High-Performance Cast Iron Emergency Shut-Off Valve for Fuel Dispensers

The HB0012 Series Emergency Shut-Off Valves (ESOV) are precision-engineered safety devices designed for submersible pump fuel dispensers. Originating from a U.S.-based OPW design, these valves automatically and rapidly stop fuel flow in emergency situations, protecting both equipment and personnel. Their robust cast iron construction and reliable fusible components make them an essential safeguard for fueling stations and industrial fueling systems.

Global Recognition and Alternative Names
These valves are widely recognized in the industry and carry different names depending on the region:
United States / Canada: ESOV valve, Emergency Shut-Off Valve, OPW fuel safety valve
Europe: emergency cut-off valve, fuel dispenser safety valve, automatic fuel shutoff
Asia: 紧急切断阀 (emergency shut-off valve), ESOV 阀门, 自动切油阀
Industry Functional Terms: fire-safe shut-off valve, rapid shut-off valve, fusible link valve

Key Features and Benefits
Robust Materials: Cast iron valve body with durable spray-paint coating; Buna-N O-rings for reliable sealing.
Automatic Emergency Shut-Off: Fusible material and cutting ring allow the valve core to close automatically if exposed to fire or impact.
Fast Response: Valve closing speed is under 1 second, ensuring immediate cutoff to prevent spillage or damage.
Wide Flow Range: Handles 0–120 L/min, suitable for gasoline, diesel, kerosene, and water.
Pressure Rating: Rated for 0.3 MPa working pressure, with emergency cutoff torque between 350–550 N•m.
Temperature Sensitivity: Lowest shut-off temperature is 75℃, providing reliable operation under high-heat scenarios.
Flexible Configurations: Single or double poppet designs with NPT or BSPT threaded connections to match diverse piping systems.

Application Scenarios
Fuel Stations: Automatic protection for submersible pump dispensers, preventing fuel spillage in fire or collision events.
Industrial Fueling Systems: Ensures safety in high-risk fueling environments.
Global Market Compatibility: Fits North America, Europe, Asia, and other regions where OPW-style ESOVs are standard.
