Description

3" Normally Closed Brass Solenoid Valve – 8621-ESM-NBR (PU225A-28)


High-flow 3" brass normally closed solenoid valve for air, water, oils, LPG, diesel, petrol, propane, inert gases and other compatible fluids. Designed for reliable operation in demanding industrial applications, the valve remains closed without power and opens only when energised.

With an extra-large 80 mm orifice and Kv flow factor of 1380 L/min, the 8621-ESM-NBR is ideal for high-flow water systems, fuel transfer applications, gas distribution systems, cooling circuits and process control installations requiring normally closed operation.

Key Features

  • Function: 2/2 way normally closed (fail-closed operation)
  • Operation: Pressure-assisted diaphragm design
  • Minimum Differential Pressure: 0.3 Bar
  • Working Pressure: 0.3 to 10 Bar
  • Port Size: 3" BSP
  • Orifice: 80 mm
  • Kv Flow Factor: 1380 L/min (water @ 1 Bar pressure drop)

Construction

  • Body: Brass
  • Internals: Stainless steel
  • Seal Material: NBR
  • Coil Power: 16 Watt DC / 15 VA AC
  • Coil Insulation: Class H
  • Duty Rating: 100% ED continuous operation
  • Protection: IP65
  • Electrical Connection: DIN 43650A Form A connector included
  • Approvals: CE, UL and CSA approved coil assembly

Media Compatibility

Suitable for:
  • Compressed air
  • Water
  • Light oils
  • Diesel fuel
  • Petrol (gasoline)
  • LPG and propane
  • Nitrogen
  • Carbon dioxide
  • Argon
  • Oxygen
  • Antifreeze and glycol solutions
  • Kerosene
  • Neutral gases and fluids compatible with valve materials
  • Maximum fluid viscosity 50 cSt

Temperature Range

  • NBR Seal: -15°C to +90°C
  • Ambient Temperature: Up to +80°C

Available Voltages

DC
  • 12V DC
  • 24V DC
  • 48V DC
  • 110V DC
  • 220V DC
AC
  • 12V AC
  • 24V AC
  • 48V AC
  • 110V AC
  • 230V AC
  • 380V AC 50/60Hz

Adjustable Opening Speed

Supplied with interchangeable pilot jets allowing the valve opening characteristics to be adjusted for different applications.
  • 1.0 mm jet – lower pressure systems
  • 0.8 mm jet – standard operation
  • 0.6 mm jet – controlled operation for higher pressure systems
  • 0.4 mm jet – anti-shock and water hammer reduction applications

This feature helps minimise pipe shock, pressure surges and water hammer effects in large fluid and gas systems.

Typical Applications

  • High-flow water systems
  • Cooling water circuits
  • Fuel transfer systems
  • LPG and propane installations
  • Process fluid control
  • Industrial automation
  • Gas distribution systems
  • Pump protection systems
  • Water hammer reduction applications
  • Fail-closed fluid and gas control systems

Benefits

  • Normally closed fail-safe operation
  • Extra high-flow Kv 1380 L/min capacity
  • Large 80 mm orifice
  • Suitable for fluids and gases
  • Adjustable operating characteristics
  • Water hammer reduction capability
  • CE, UL and CSA approved coil assembly
  • Long service life
  • Fast UK delivery available
