Carbon Steel Diaphragm Type Pressure Reducing Valve For Water And Air Use
Pressure reducing valve's main purpose is to convert increased pressure into lower pressure. It is also known as a pressure lowering regulator. A self-acting automatic control valve that reduces a greater, unregulated entrance pressure to a constant, decreased exit pressure regardless of changes in the upstream water pressure is known as a pressure lowering valve. Without requiring an external power source, it can regulate pressure due to its totally autonomous self-contained functioning. By opening as the pressure rises and closing as it decreases, it lowers the downstream pressure until it equals the setpoint. These mechanical valves are straightforward and dependable to use since they use a spring against a piston or diaphragm as the control element. Larger diaphragm sizes are used in more specialized models to boost sensitivity for lower pressure ranges. They are frequently used in the oil and gas, steam, and water sectors.
