General Specifications

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

Cycle Life

The valves will typically operate across a minimum of 250 million cycles on water, depending on application conditions.

Weight

8 to 10 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 40°F to 120°F (4°C to 49°C)
  • Maximum coil temperature not to exceed 150°F (66°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.

Storage Conditions

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

Electrical Characteristics

  • The INK Series valves require the use of a spike and hold drive to achieve the specified operating frequency. Click here for recommended electrical drive schematics.
  • The Lee Company offers a Spike and Hold Driver (Lee Company Part Number IECX0501350A) for development use.
  • The valves are designed to operate at the rated voltage ± 5%, unless otherwise specified.

Electrical Connections

  • PV275 Model: These valves are designed to be mounted onto a printed circuit board.
  • 600LT Model: These valves are designed with axial 0.025" sq. pins that are spaced 0.200" center to center. The Lee Company offers a lead-wire connector assembly (Lee Company Part Number IHWX0248020A) as a separate accessory that is compatible with this pin spacing.

Response Time

  • The response time is based on the spike and hold drive parameters, along with the maximum operating frequency of the specific valve design.
  • 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.

Port Connections

  • The INK Series valves are designed for use with soft, flexible tubing. Refer to the individual valve drawings on the PC Board Mount and Axial Pin Mount pages for size requirements.
  • The dispense output is affected by the tubing length, durometer, size and material.
  • Refer to MINSTAC for various tubing and components to be used with the INK Series valves.

Mounting Information

Axial Pin Mount: The valves may be mounted to a flat surface using #2 (M2) screws and there must be sufficient length to allow for valve thickness and proper thread engagement into the mounting surface. The recommended mounting torque is 10 to 15 in-oz. (0.071 to 0.106 N-m). Refer to valve drawing for detailed specifications.

Filtration

Filtration of 35 microns or finer is recommended.
