Constant Pressure Regulating Sanitary Pressure Relief Valve With Butt Weld End DN15-DN100
Quick Details
- Vavle body and disc are made of best 316L or 304 stainless steel
- Outside surface is treated by sandblasting
- The diaphragm material can be EPDM or PTFE, high temperature standable upto 140 degrees
- Butt weld connection end offers simple and fast installation, strong and no leakage
- Very popular to regulate medium pressure in the pipeline or tank at a set pressure value
- Valve cover and seat are fixed by tri clamp
Working Principle
- The valve is normally closed when the medium pressure is within set value
- When medium pressure increases, the diaphragm is pushed upwards
- Valve stem moves upwards accordingly
- Medium then flows out of the valve, make the pipeline pressure reduces
- The diaphragm is pushed back by the air pressure in upper chamber
- The diaphragm keeps moving downwards until the valve is closed
