The following specifications apply to all LGV Series genvi™ control valves, unless otherwise noted.
Maximum of 25 SµLPM of air at 15 psid (70°F) with pressure applied to the common port.
The cycle life of the genvi solenoid valves will vary depending on the application conditions. Unless otherwise specified, under standard conditions on air, valves with an FKM seal will typically operate across a minimum of 25 million cycles.
The valves will operate within the specified pressure range when supplied with the rated voltage ± 5%. The valve is spring loaded, so the highest absolute pressure must be maintained at the common port unless otherwise indicated. Reference the porting flow schematic on individual valve inspection drawings.
- Valve Proof Pressure: 2X Normal Rated Pressure
- Valve Burst Pressure: 3X Normal Rated Pressure
- Ambient operating temperature range is 40°F to 120°F (4°C to 49°C), unless otherwise noted.
- Increasing the operating temperature tends to limit coil performance. The valve duty cycle and energized time must be evaluated for conformance with the maximum recommended operating and coil temperatures. Maximum coil temperature not to exceed 250°F (121°C).
- Temperature: - 40°F to 175°F (-40°C to 80°C)
- Relative humidity: 85% max., non-condensing
The response time is 10 milliseconds maximum. Response times are dependent upon system conditions, power, environment, etc. The response time will typically increase as the ambient temperature decreases. Extended periods of inactivity may also have an impact on the initial response time of the valve.
The valve is constructed with wetted materials intended to flow air and compatible gases. While The Lee Company can offer material recommendations based on your flow media, it is important and necessary to verify compatibility of our products with the fluid media and conditions of your specific application.
Filtration of 35 microns or finer is required. Click here for additional information.
- Coil resistance: 24 ohms nominal.
- Incorporating the appropriate electrical drive is essential to avoid permanent damage caused by overheating.
- A spike and hold drive is required to achieve high flow performance while minimizing power and heat across an extended operating cycle.
- Requires a spike voltage of 12 +/- 5% VDC for 10 to 30 milliseconds before dropping the valve to a hold voltage of 2.75 +/- 5% for the remaining on-time. The valve is rated for continuous duty at the specified hold voltage. However, to allow the coil adequate time to cool, it is important to ensure the average power does not exceed 1.5W over any discrete energized/de-energized cycle.
