Marine DIN German Standard Pressure Reducing Valve, JIS Japanese Standard Pressure Reducing Valve, ANSI/API American Standard Pressure Reducing Valve

Water Pressure Reducing Valve: (Also known as Pressure Stabilizing Valve) Available in piston and diaphragm types. The diaphragm type regulates the flow of media by adjusting the opening of the closure element inside the valve body, reducing the pressure of the media, while using the pressure after the valve to adjust the opening of the closure element to maintain the outlet pressure within a certain range. Select the type and pressure regulation accuracy of the pressure reducing valve based on usage requirements, and then choose the diameter according to the required maximum output flow. When determining the air source pressure of the valve, it should be greater than the maximum output pressure by 0.1MPa.

Product Overview:

Nominal Pressure: 1.6MPa Working Media: Water Working Temperature: 0°C < T ≤ 80°C Maximum Inlet Pressure: 1.6MPa Outlet Pressure Adjustment Range when Inlet Pressure is 1.6MPa: 0.10～0.60MPa Factory Set Outlet Pressure: 0.3MPa
