A Direct Acting Pressure Reducing Valve Manufacturer in USA is a control valve that reduces the pressure of a fluid to a desired output value. It’s designed to be self-acting and compact and is often used for saturated steam and compressed air.
Working:
When flow begins, the diaphragm moves the valve seat away from the valve seal to allow flow. When there is no flow, the downstream pressure increases and pulls the valve seat up against the valve seal to close the valve. The required outlet pressure is set using a dial on top of the valve. Turning the dial adjusts the tension on the internal compression spring, which holds the diaphragm in place. Rotating the handwheel in a clockwise direction causes a downward movement, which compresses the control spring and extends the bellows to set the downstream pressure. This downward movement is transmitted via a pushrod, which causes the main valve to open.
Direct Acting Pressure Reducing Valve Manufacturer in USA here are the advantages:

Industries:
1. Building
2. Steam
3. Water
Components:
1. Valve body: Stabilizes the return of flow and regulates pressure
2. Diaphragm: Controls the valve’s position against a spring pressure
Adjustment spring and screw: Work with the diaphragm to control the valve position
3. Pilot valve: Used in pilot-operated pressure-reducing valves to load a piston or diaphragm.
