Male Thread Sanitary Pressure Relief Valve , Stainless Steel Pressure Relief Valve

BSP / BSPT / NPT Male Thread Conection Hygienic Constant Pressure Regulating Pressure Relief Valve

Raw Materials:

• Valve body: stainless steel, 316L
• Valve cover: stainless steel, 304
• The uppper diaphragm: NBR(Standard), EPDM / PTFE(Optional)
• The bottom diaphragm: PTFE / EPDM
• O ring: NBR or Viton
• Surface treatment: matt

Operation Principle:

The constant pressure regulating valve is installed in a hygienic pipeline or a tank, together with a compressed air pressure regulating facility and a pressure gauge. The diaphragm and valve disc system inside the valve is very sensitive to any pressure change of the medium fluid. It replies by changing the valve stem position to open or close the valve, in order keep the pressure of pipeline or tank at a certain value. 

When the medium pressure increases, the valve will open and discharge excessive medium. When the medium pressure reduces, the valve will close accordingly.
