500X pressure relief and pressure sustaining valve is mainly used to adjust the medium flow, pressure, temperature, liquid level and other process parameters in the field of industrial automation process control. According to the control signal in the automation system, the valve opening is automatically adjusted to achieve the adjustment of medium flow, pressure, temperature and liquid level.
A Pressure Reducing Valve (PRV) is an Automatic Control Valve designed to reduce a higher unregulated inlet pressure to a constant, reduced downstream (outlet) pressure regardless of variations in demand and/or upstream (inlet) water pressure.
