Negative pressure pneumatic safety valve working principle and technical parameters

the negative pressure pneumatic valve is safe sanitary stainless steel pneumatic valve, its security design makes it can protect the equipment, so it is installed in the discharge pressure loop, for piping, pump, safety protection device, storage tank, etc. Widely used in food, beverage, dairy, pharmaceutical, beer, etc.
negative pressure safety working principle of the pneumatic valve pneumatic valve
negative pressure safety is by adjusting the spring pressure calibration nut to a certain pressure. Calibration pressure is to avoid the equipment damage of maximum safe pressure. Under normal working pressure, pneumatic valve is closed; When the system pressure exceeds the calibration, pneumatic valve to open. The pressure in the pipe system was released, so as to achieve the protection of piping and equipment.
security pneumatic valve is a relatively special pneumatic valves, all through the strict check at the factory, but in order to make the pneumatic valve can be more practical operation condition, so the conditional, should as far as possible field of pneumatic valve and check again.
it increased the pneumatic opening device, easy to CIP cleaning safety pneumatic valve and piping.
