Constant Pressure Regulating Sanitary Pressure Relief Valve With Butt Weld End DN15-DN100

DN15 ~ DN100 Sanitary Constant Pressure Regulating Pressure Relief Valve With Butt Weld End

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
