Its lightweight design supports flexible horizontal or vertical installation, making it especially suitable for equipment interfaces, branch pipelines and centralized piping scenarios of instrument panels.3. Direct-Acting Sensitive AdjustmentEquipped with a linkage mechanism of precision diaphragm and pressure regulating spring, it responds quickly to pressure fluctuations and can automatically maintain stable set pressure. The adjusting knob is equipped with a scale indicator, supporting stepless pressure regulation (common range 0.05-0.8MPa). The adjustment process is synchronized with the pressure gauge display, realizing "what you see is what you get" precise control.4. Built-In Filtration and Anti-Interference DesignThe water inlet end of the valve is standard equipped with a stainless steel filter screen (above 100 meshes), which effectively intercepts pipeline impurities and protects the valve core and pressure gauge transmission mechanism. The pressure gauge connection part adopts diaphragm sealing or damping design, reducing the impact of medium pulses on the pressure gauge pointer and extending the service life of the instrument.5. Convenient Maintenance and Safety ReliabilityThe pressure gauge and valve body adopt a separable connection, supporting independent calibration or replacement. The key sealing components of the valve adopt a modular design, and no overall disassembly is required during maintenance. All flow-passing parts of the valve are made of corrosion-resistant materials, suitable for cold water, hot water, compressed air and non-corrosive liquid media, ensuring long-term stable operation.
