The relief valve 1502 is an essential component for protecting high-pressure systems and ensuring equipment safety.
This relief valve provides reliable operation in critical applications, including mud pumps, hydraulic fracturing, and chemical processes.
Available in 2” and 3” models, including Spring Style Relief Valve, 3” Spring Actuated Relief Valve, and 3” EXL N2 Back Pressure Relief Valve.

Main Features of the RELIEF VALVE 1502

1. Materials and Construction of the RELIEF VALVE:
   • Made of high-strength steels (AISI 4140 or 316SS) to withstand high pressures and corrosive fluids.
   • Elastomeric or metal seals depending on model, ensuring tightness and durability.
2. Pressure Range of the RELIEF VALVE:
   • Operates from 500 to 15,000 psi (34.5 to 1,034 bar), adjustable according to industrial configuration.
3. Actuation Mechanism of the RELIEF VALVE:
   • Calibrated spring opens the valve when pressure exceeds the set limit, ensuring fast and controlled release.
   • Conical or spherical seat for tight sealing and efficient response.
4. Connections and Sizes of the RELIEF VALVE:
   • Threaded (NPT) or flanged (ANSI/ASME) connections according to industrial standards.
   • Available sizes: ½”, 2”, and 3” nominal diameter for diverse applications.
5. Applications of the RELIEF VALVE:
   • Oil industry: mud pumps, hydraulic fracturing, loading/unloading systems.
   • Hydraulic systems in heavy machinery and critical pressure equipment.
   • Chemical processes requiring high-pressure fluid control and maximum safety.

Advantages of the RELIEF VALVE 1502

• Precision: Maintains system pressure within safe margins, preventing overpressure and equipment failures.
• Durability: Resistant to repeated open/close cycles and extreme operating conditions.
• Maintenance: Modular design facilitates inspection, repair, or replacement of critical components.

Considerations for the RELIEF VALVE

• Requires periodic spring calibration to ensure optimal and safe performance.
• Select according to fluid type, chemical compatibility, and operating conditions (temperature, pressure).
• Verify size and model compatibility with the specific industrial installation to ensure efficiency.

In summary, the relief valve 1502 is a critical component for safety and reliability in high-pressure systems. 2” and 3” models cover critical industrial applications, ensuring continuous protection and efficient operation.
