Description

2½" Normally Closed Brass Solenoid Valve – 8620-ESM-NBR


The 8620-ESM-NBR (PU225A-24) is an extra high-flow 2½" normally closed brass solenoid valve designed for industrial air, water, oils, fuels, gases and compatible fluid control applications.

Its pressure-assisted diaphragm design combines a large 65mm orifice with an exceptional Kv flow factor of 1050 L/min, while requiring only 0.3 Bar minimum differential pressure for operation.

Interchangeable pilot jets allow the valve opening speed to be tailored to the installation, including slower controlled opening to help reduce pressure shock and water hammer in large-bore pipework.

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
Antifreeze and glycol solutions
Kerosene
Neutral gases and fluids compatible with valve materials
Maximum fluid viscosity 50 cSt

Temperature Range

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

Had been looking for a 21/2" brass solenoid valve all over the UK, these guys had one is stock great price and I must say an amazing next day tracked and ETA on time delivery system that kept me informed on delivery time to with 15 minutes. I must say this was a great help and allowed me to get on with my day without needing to sit and wait in all day. Thanks for the solenoid valve catalogue too, I did not know you offered angle 21/2 "seat piston valves and pressure control valves too. I'll be back. Thanks Roger CV.
