General Information:
Duravis ESV 500-501 series solenoid valves are designed for high-pressure refrigerant gas applications. These valves operate as normally closed (NC) and offer safe, fast, and leak-free operation. With a compact structure, they are also suitable for narrow installation areas.

Technical Specifications:

  • Body Material: Brass

  • Connection Type: Solder connection

  • Connection Sizes: 1/4”, 3/8”, 1/2”

  • Valve Type: 2/2 Way, Normally Closed (NC)

  • Operation Principle:

    • ESV 500: Direct acting

    • ESV 501: Semi-direct (pilot assisted)

  • Pressure Range:

    • ESV 500: 0 – 25 bar

    • ESV 501: 0.3 – 30 bar

  • Temperature Range: -40°C ~ +130°C

  • Suitable Media: R134a, R404A, R407C, R410A

  • Coil Voltages: 24V DC, 220V AC

  • Protection Class: IP65 (with coil)

  • Seal Material: Neoprene or Viton

Application Areas:

  • Refrigeration systems

  • Compressor control lines

  • HVAC systems

  • Automatic refrigerant control circuits

Mounting Position:
Vertical mounting (coil upwards) is recommended. Horizontal mounting is possible but vertical ensures better sealing and reliability.
