Proportional isolation valves by Clippard lead the industry in performance

Clippard’s Eclipse line of proportional isolation valves is available from Wainbee.

Wainbee Limited supplies world-class industrial equipment that stands out not only for its effectiveness, but also for its innovation. These are products and solutions that go a step further in fulfilling today’s industrial needs, looking to the future. A key example is Clippard’s Eclipse line of proportional isolation valves.

These two-way, stepper-controlled valves lead the industry in performance and durability, in part by using the most robust and powerful miniature linear actuator on the market.

Quick response and excellent linearity

Clippard’s family of Eclipse proportional isolation valves is perfect for critical applications for liquid and gas delivery and for medical, analytical, and industrial automation that need ultrafine resolution and repeatability. Their unique design enables custom flow profiles too. Other benefits include quick response (less than two milliseconds of reaction time), excellent linearity (less than four per cent of full-scale), no leakage (under 0.05 sccm), a lifespan of more than 1,000,000 cycles, and repeatability of under ½ per cent of full travel.

Other features of these Eclipse proportional isolation valves from Wainbee:

• Medium: liquids and gases;
• Typical cycle time for full travel: 1.1 seconds at 1,000 steps per second;
• Wetted material: Other material options available, depending on porting;
• Pressure range: Vac to 30 psig;
• Proof pressure (overpressure): 50 psig;
• Flow range at 30 psig: air – zero to eight litres per minute -0/+10 per cent (0.28 scfm); water – zero to 210 millilitres per minute -0/+10 per cent (0.0074 scfm)
• Maximum flow resolution: 0.19 millilitres per minute (water) and 0.007 litres per minute (air) at 30 psig per full step, depending on pressure;
• Position resolution: 0.00006 inches per step;
• Ambient/environment: zero to 82 degrees Celsius;
• Driver required: bipolar chopper drive;
• Supply voltage to motor driver: 20 VDC at 30 psig;
