Control solenoid valves are commonly used in medical, scientific, or industrial devices to control flow or pressure in pneumatic systems. Typically, they select between multiple gases or between pneumatic pressure and vacuum sources. They also vent pressurized volumes to the atmosphere and direct a flow path to sensors or reaction chambers. We offer a variety of control solenoid valve designs, including magnetically-latched valves that do not require continuous power to hold their flow state. This provides you with significant power savings, especially crucial for battery-powered devices. Low power and compact valve designs also simplify sample piloting in microfluidic or air-over-gasket applications. Our quiet operation solenoid valves reduce actuation sound, thereby improving patient comfort in bedside devices. With our solenoid valves, your instrument also benefits from low pneumatic leakage, reducing compressor demand, and improving accuracy when blending and delivering gases.
High-speed dispensing valves are commonly used in medical, scientific, or industrial devices to accurately and precisely dose liquids. They can dispense flawless droplets into a well plate, inject precise volumes directly into a flow stream, or provide consistent spray patterns through integrated nozzles and orifices. Our wide range of dispense solenoid valves offer high-speed, microsecond operation and enable nanoliter droplet dispensing. Their small, 6 mm size allows tight and flexible packaging in encased instruments or moving robotic arms.
Many medical, scientific, or industrial instruments require isolation solenoid valves to precisely control aggressive fluids. Typically, they select between multiple fluids, dispense reagents or flush the fluidic system clean before the next cycle. Our isolation solenoid valves are designed to be chemically compatible with many reactive and corrosive fluids, and their low leakage prevents fluids from reacting with other system components. With a wetted flow path consisting solely of chemically inert materials, you get robust performance across an extensive cycle life, reducing your system maintenance and cost. Their low carryover volume improves flow selection, and our zero dead volume designs allow biologicals to be fully flushed from the flow path.
Flow control of high-pressure hydraulic and pneumatic fluids requires minimal leakage, fast response times, and low power consumption for applications such as those on aircraft, space systems, downhole and subsea oil and gas equipment, and motorsports. Solenoid operated control can be complex. You need rugged, field-proven designs for long life in harsh conditions. In high-pressure systems, it’s often critical to ensure the packaging can fit within tight spaces with minimal weight. We will work with your engineers to tailor valve performance to the needs of your individual applications.
