Series XRFU and XRFO flow control valves

Flow Control Excellence in Stainless Steel: Series XRFU & XRFO Valves

When it comes to precise and reliable flow control in harsh environments, the Series XRFU and Series XRFO valves stand out for their robust construction and versatile functionality. Manufactured with 316L stainless steel, these valves offer exceptional corrosion resistance and durability, making them ideal for applications involving aggressive fluids or gases.

The XRFU Series features unidirectional flow control valves, primarily used for regulating cylinder speed in pneumatic systems. In contrast, the XRFO Series provides bidirectional flow control, allowing precise air and fluid regulation in both directions. Both series employ needle-type valve technology for fine control and dependable performance.
