Designed for Critical Applications
The VPWS-1-B-6-PC15-10-V is particularly suited for medical technology, including ventilation and anesthesia systems, as well as laparoscopy and colonoscopy equipment. Its oxygen compatibility per ISO 15001 and low hydrocarbon contamination (max. 550 mg/m²) make it a safe choice for respiratory and surgical applications. The valve also meets the requirements of electronics, semiconductor, biotech, and pharmaceutical industries, where precise dosing of gases is essential for process integrity.
Integration and Mounting Flexibility
This valve offers multiple mounting options: on a sub-base, plug-in, or with accessories. Its cartridge-style pneumatic connections (15 mm and 7.2 mm) allow for compact manifold integration, saving valuable space in OEM equipment. The electrical connection is a simple 2-wire cable with open ends, simplifying wiring in control cabinets. The valve can be mounted in any position, and its low weight (23 g) minimizes mechanical stress on supporting structures.
Reliability and Environmental Considerations
Engineered for consistent operation, the VPWS-1-B-6-PC15-10-V withstands vibration and shock per FN 942017-4/5 and EN 60068-2-6/27 (severity level 1). Note that vibration or shock in the Z-direction may cause flow fluctuations, so orientation should be considered during design. The valve is RoHS-compliant and conforms to VDMA24364 zone III (LABS/PWIS), making it suitable for use in paint and coating environments. With a corrosion resistance class of 1, it is intended for low-corrosion stress applications. The housing is made of high-alloy steel, and seals are FPM, ensuring durability in demanding media.
For engineers seeking a compact, high-flow proportional valve with precise control and medical-grade oxygen compatibility, the Festo VPWS-1-B-6-PC15-10-V offers a practical solution. Its straightforward integration and robust design reduce development time and enhance system reliability.
