The FOX VR Series Nitrogen Valve represents a technical solution designed for the safe and reliable management of fluids and gases within complex industrial systems. Developed to ensure optimal performance over time, this valve is a fundamental element for the correct operation and routine or extraordinary maintenance of hydraulic systems.<\/p>\n

Construction Features and Materials<\/h3>\n

The standard valve configuration features a robust body made of steel, treated with trivalent zinc plating. This surface finish gives the component strong resistance, ensuring durability even in the most demanding working environments. The careful selection of construction materials highlights the series\u2019 orientation toward applications where safety and pressure tightness are essential requirements. From a technical standpoint, the dimensional data and ports confirm compatibility with standard connections, including 5\/8″ UNF and 3\/8″ BSP formats, ensuring easy and quick integration into existing circuits.<\/p>\n

Available Versions and Models<\/h3>\n

To meet different application and chemical-resistance requirements, the range includes several construction variants based on the use of stainless steels. Specifically, the series includes:<\/p>\n

    \n
  • \n

    VRX Model<\/b>: Made entirely of AISI316L stainless steel, it is ideal for environments requiring high corrosion resistance.<\/p>\n<\/li>\n

  • \n

    VRXHD Model<\/b>: This is a \u201cHeavy-Duty\u201d variant, also made of AISI316L stainless steel and specifically engineered to withstand severe stress and high mechanical load installations.<\/p>\n<\/li>\n

  • \n

    VR14 and VRX14 Models<\/b>: Versions equipped with 1\/4″ BSP-M x 5\/8″ UNF connections. The VR14 model is made of galvanized steel, while the VRX14 variant is made of stainless steel, ensuring maximum versatility of use according to the fluid used.<\/p>\n<\/li>\n<\/ul>\n

    Applications and Fields of Use<\/h3>\n

    The valve\u2019s operational flexibility allows installation in multiple industrial scenarios. The main documented applications include:<\/p>\n

      \n
    • \n

      Accumulators and Dampers<\/b>: The valve is an essential component for interfacing with accumulators and pulsation dampers.<\/p>\n<\/li>\n

    • \n

      Pressure Control<\/b>: It is particularly suitable for accurately controlling or varying pressure levels in any system operating with either gas or fluid.<\/p>\n<\/li>\n

    • \n

      Closed Hydraulic Circuits<\/b>: It is practically used for air bleeding operations inside closed hydraulic circuits.<\/p>\n<\/li>\n<\/ul>\n

      Interaction with Maintenance and Safety Tools<\/h3>\n

      During operating phases, the valve interfaces with the charging and testing unit (AR Series), which is screwed directly onto the accumulator nitrogen valve to monitor internal pressure. The manufacturer strictly recommends that, during charging operations carried out through the circuit, a pressure reducer must always be installed at the cylinder outlet. This precaution is mandatory to prevent incorrect operations from subjecting the accumulator to pressures above the maximum permitted limit, compromising its operation and safety. In this regard, periodic system inspection is recommended every six months of operation.<\/p>\n
