Description
Product Description
The DECAR ZZY Self-operated Micro-pressure Regulating Valve is designed for automatic regulation of low-pressure systems where precise control of micro-pressure levels is required. The valve operates without external energy, using the pressure of the controlled medium to drive the regulating mechanism.
The valve features a single-seat regulating structure combined with a diaphragm actuator, enabling the valve to respond to small pressure variations in the pipeline. When pressure changes occur, the diaphragm mechanism adjusts the valve opening to maintain the preset pressure value within the system.
This valve is designed for applications involving low-pressure or micro-pressure control, particularly where stable regulation is required and installation conditions do not permit the use of external power or control instrumentation. The design allows the valve to maintain reliable pressure control with a simple and efficient operating principle.
The ZZY micro-pressure regulating valve series is available in various sizes and pressure adjustment ranges, allowing it to be configured according to specific operating conditions and process requirements.
