Compact Proportional Control for Tight Spaces
The Festo VPWS-0.3-B-6-PC8-10-V (manufacturer ID 8186784) is a 2/2 proportional directional control valve, normally closed, engineered for precise gas flow regulation in applications where installation space is at a premium. With a nominal width of 0.3 mm and a product weight of just 5 g, this directly controlled poppet valve fits into compact assemblies without compromising control accuracy. Its soft sealing principle and mechanical spring reset ensure reliable shut-off and consistent performance, even in sensitive environments.
Technical Profile for Critical Gas Applications
This valve is electrically actuated and operates with a direct control type, offering a standard flow rate range of 6.6 to 8 l/min. The operating pressure spans from 0 to 10 bar (nominal 145 psi), with a burst pressure of 435 psi. The current regulating range is 0 to 70 mA, and the valve exhibits a hysteresis of 14 mA. Maximum switching frequency is 25 Hz, and the coil resistance is 308 Ohm. Power consumption is limited to 1.5 W, with a 100% duty cycle (refer to operating instructions). The valve is designed for inert gas and air, with a maximum particle size of 10 μm; oil lubrication is not permitted. Medium and ambient temperatures range from 5°C to 50°C, while storage temperature extends from -40°C to 80°C.
Integration and Mounting Flexibility
The VPWS-0.3-B-6-PC8-10-V offers versatile mounting options: it can be mounted on a sub-base, plugged in, or used with accessories. The mounting position is unrestricted, simplifying system design. Pneumatic connections are cartridge-type: 8 mm on connection 1 and 5.8 mm on connection 2. The electrical connection is a 2-wire cable with open ends, 0.07 to 0.08 m long, allowing direct wiring to control circuits. The valve's degree of protection is IP60, but with a suitable plug in the mounted state, it achieves IP65, making it suitable for environments with occasional dust or moisture exposure.
Designed for Medical and Analytical Equipment
This valve is particularly suited for medical technology and biotech applications, including ventilation and anesthesia systems, laparoscopy and colonoscopy instruments, and compressed-air-driven operating tools. Its compact size and low weight are advantageous for portable or handheld devices. The valve meets LABS (PWIS) conformity to VDMA24364 zone III, ensuring it is free from materials that could affect paint adhesion—a critical requirement in many industrial and medical settings. The housing is made of high-alloy steel, and seals are FPM, both RoHS-compliant. The valve is rated for low corrosion stress (CRC 1), making it appropriate for controlled environments.
Practical Considerations for Engineers
When integrating this valve, note that flow direction is non-reversible, so orientation must be correct. Vibration and shock resistance are tested to severity level 1 per FN 942017-4/-5 and EN 60068-2-6/-27; however, vibration or shock in the Z-direction can cause flow fluctuations—designers should account for this in mounting orientation. The valve is not suitable for oil-lubricated air, and filtration to 10 μm is recommended. With a 100% duty cycle and low power consumption, it is suitable for continuous operation. The product weight of 5 g and compact dimensions make it an excellent choice for miniaturized systems where precise gas flow control is essential.
