The FOX VM Series Nitrogen Valve represents an outstanding technical solution, specifically developed for installation on accumulators and dampers within industrial, hydraulic and process systems. Manufactured by FOX s.r.l., based in Opera (MI), Italy, this valve guarantees maximum reliability for interfacing and maintaining pressurized systems. The use of this component is essential for managing pressure control or variation with absolute precision in any system operating with gas or fluid.

Construction Features and Materials

The design of the FOX VM Series Nitrogen Valve includes different configurations to meet a wide range of environmental and operating requirements. The standard version features a body made of steel treated with trivalent zinc plating, a choice that provides structural strength and excellent protection for conventional applications.

For integration into more severe environments or systems where superior corrosion resistance is required, the series is available in two additional high-performance configurations:

  • VRMX Model: This variant is made entirely of AISI316L stainless steel, a material suitable for the chemical or process industry.

  • VRMXHD Model: Also made of AISI316L stainless steel, this model has been structurally optimized and reinforced specifically for heavy-duty installations.

Strategic Applications and Fields of Use

The valve’s versatility allows it to be used in different technical fields. The three main documented applications cover the primary industrial use cases:

  • Accumulator Systems: The valve is the ideal component for direct installation on accumulators and pulsation dampers.

  • System Regulation: It can be used to perform pressure variation and monitoring in mixed gas or industrial fluid systems.

  • Circuit Maintenance: It is widely used to carry out air bleeding operations in closed hydraulic circuits, a critical procedure for avoiding performance drops and preserving machinery integrity.
