General Specifications

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

Cycle Life

The valves will typically operate across a minimum of 10 million cycles on water, depending on application conditions.

Weight

6 grams

Operating Pressure

The valves will operate within the specified pressure range when supplied with the rated voltage ± 5%.

  • Valve Proof Pressure: 2x Normal Rated Pressure
  • Valve Burst Pressure: 3x Normal Rated Pressure

Operating Temperature

  • Ambient operating temperature range is dependent on the elastomer; refer to the table below for details.
  • Maximum coil temperature not to exceed 170°F (77°C).
  • Increasing the operating temperature tends to limit coil performance. The valve duty cycle and energized time must be evaluated for conformance with the maximum rated operating and coil temperatures.

ELASTOMER AMBIENT OPERATING TEMPERATURE RANGE
EPDM 30°F to 120°F (-1°C to 49°C)
FKM 40°F to 120°F (4°C to 49°C)

Storage Conditions

  • Temperature: -40°F to 175°F (-40°C to 80°C)
  • Relative humidity: 85% (max); non-condensing

Response Time

  • The typical response time is 20 ms maximum at 68°F (20°C), 2Hz on air at 10 psig.
  • Response times are dependent upon system conditions, power, environment, etc. The response will typically increase as the ambient operating temperature decreases. Extended periods of valve inactivity may also have an impact on the initial response time of the valve.
  • Response times can be enhanced with the use of spike and hold drive circuits.  Refer to the electrical characteristics below.

Electrical Characteristics

  • Valves are designed to operate under continuous duty at the rated voltage ±5%.
  • The valves are also designed to be operated using a spike and hold drive approach to enhance response time and reduce the average power consumption.

Mounting Information

Flange Mount: The valves should be mounted to a surface using #1-64 x 0.1875 (M1.6) mounting screws. The torque specification is 5 to 7 in-oz (0.035 to 0.049 N-m). Click here for mounting details.

Filtration

Filtration of 35 microns or finer is recommended.
