The Type ‘D’ Fig. No. D10 Pressure Reducing Valve is a direct-operated, diaphragm-actuated, single-seat valve designed to automatically regulate downstream pressure. The valve operates through a spring-loaded mechanism, where the outlet pressure acts on the diaphragm to modulate the valve position, ensuring consistent pressure control in response to system demand.
As the downstream pressure varies, the diaphragm adjusts the valve opening or closing against the flow direction according to the preset spring tension, maintaining the desired reduced pressure.
This valve is particularly suitable for applications requiring tight shut-off performance and reliable pressure regulation in services involving water, compressed air, gases, oils, and a wide range of chemical fluids.
