The VSO® LowPro is a miniature proportional valve that controls the flow rate of inert gases. Typical flow rates up to 50 SLPM with a maximum of 1.5 Watts at room temperature. At just 16 mm wide by 14 mm tall, the valve can be populated into the smallest portable device improving performance, size and weight. With an orifice of up to 0.080” (2.03 mm) and a weight of 12 g, the VSO® LowPro can perform the function of valves three times its size without sacrificing the power. Mounting only requires a simple, machined manifold.
Features
• Very low power required of typically 1 Watt enables portable capability and low power control increasing battery life or reducing the size of your power supply or battery• Low profile design simplifies mounting and eliminates cartridge configurations that require complex & expensive machining
• Delivers consistent performance on every valve
• Reach, RoHS, ISO 15001, IP65, and CE compliant
Markets
