Type- Pressure Regulating Valve FGR

Graded pressure regulation: The standard model has a diaphragm structure with an adjustment range of 0.05MPa~1.0MPa, which meets the needs of normal working conditions; the precision model is upgraded with a high-precision structure with a pressure deviation of ≤0.01MPa, which is suitable for precision equipment.

Easy to operate: Knob adjustment + pointer pressure gauge for intuitive pressure reading; precision models feature pressure lock to prevent accidental operation.

Safe and reliable: Built-in overflow structure for automatic overpressure venting; aluminum alloy shell with anodized corrosion resistance; seals that are oil-resistant and aging-resistant.

High adaptability: Interface coverage ranges from 1/8′′ to 2′′, supports tubular/plate mounting, and can be modularly combined with filters and oil mist lubricators.

Excellent flow rate: Large-diameter models have strong flow capacity, meeting the pressure regulation requirements of high-flow pneumatic systems.

    Detailed description

    The Type-Pressure Regulating Valve FGR is designed to provide stable and adaptable pressure control for pneumatic systems, with configurations available to suit both general industrial applications and more demanding precision environments. The standard model utilizes a diaphragm-type structure that offers a pressure adjustment range of 0.05MPa to 1.0MPa, making it suitable for a wide variety of typical operating conditions. For applications that require tighter control, a precision model is available, featuring an enhanced design that maintains pressure deviation within ≤0.01MPa, making it well-suited for use with sensitive or precision equipment.

    Operation is straightforward, with a knob-style adjustment mechanism paired with a pointer-type pressure gauge that allows users to monitor output pressure directly at a glance. On the precision model, a pressure lock function is incorporated to help prevent unintended adjustments after the desired pressure has been set, contributing to more consistent operation in applications where stability is critical.

    Safety features include a built-in overflow structure that automatically relieves excess pressure, helping to protect downstream components from overpressure conditions. The housing is constructed from aluminum alloy with an anodized surface treatment, providing reliable corrosion resistance for long-term use in industrial environments. Seals used throughout the valve are selected for resistance to oil and aging, supporting consistent performance over extended periods of operation.

    Adaptability is supported through a wide range of interface options, with port sizes spanning from 1/8 inch to 2 inches. The valve can be installed using either tubular or plate mounting methods, offering flexibility to suit different system layouts. Additionally, the unit is designed for modular integration, allowing it to be combined with filters and lubricators to form a complete air preparation assembly as needed.

    For systems with higher flow demands, large-diameter models offer enhanced flow capacity, ensuring that pressure regulation remains stable even under higher-volume conditions. Overall, the FGR pressure regulating valve combines consistent performance, flexible installation, and reliable construction to support effective pressure management across a broad range of pneumatic applications.
