LFN Series Solenoid Valves

General Specifications

The following specifications apply to all LFN Series valves, unless otherwise noted.

Cycle Life

LFN Series solenoid valves will operate for a minimum of 10 million cycles (clean water at 68°F and 10 psi). System fluid and operating conditions may affect performance.

Response Time

Typical response time is 20 ms or less at 68°F (20°C), 2 Hz air @ 10 psig. Response times can be enhanced by using a spike and hold circuit.

Electrical

  • LFN valves are designed to operate continuously using the nominal rated voltage (+/-5%). Response times can be enhanced by using a spike and hold circuit.

Operating Pressure

LFN valves are designed to operate from vacuum to 30 psig.

  • Valve Proof pressure: 60 psig
  • Valve Burst pressure: 90 psig

Operating Temperature

LFN valves are designed to operate in the range shown below.

  • Ambient operating temperature is 40-120°F (4-49°C)
  • Max coil temperature: 150°F (66°C)

Filtration

Filtration of 35 microns or finer is recommended.
