Basic Info
Model No.: QZH-89
Product Description
Model NO.: QZH-89 Class: 150lb to 2500lb Application Fields: Metallurgy,Light Industrial,Electric Power,Petroch Trademark: NIPO Origin: Wenzhou, Zhejiang, China Size: Dn50 - Dn300 Certificates: API 6D, CE, ISO9001 Delivery Detail: 20~45 Days According to The Specific Quantities Specification: API6D, ISO9001, CE, SGS, etc HS Code: 8481804090 All-weather fire proof &explosion-proof breathing valve
Breathing valve is a kind of air breather which install on the petrochemical fixed storage tank, in order to avoid tank over the pressure or vacuum making the storage tank destruct, prevent the outside flame enter, reduce the tank fluid volatile.
Explosion-proof fire breathing valve is to maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use of principles of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work, equipped with fire retardant explosion-proof function.
Fire breathing valve produced by our company has simplified structure, ventilation volume, less leakage, corrosion resistance, insulation, etc.
The valve adopts polytetrafluoroethylene material, has the advantages of low temperature resistant, anti frost.
The electrostaticprotection device is provided with a respiratory valve, the valve and the tank to keep the same potential moment.
Operating pressure: Type A: +355pa(+36mmH2O) -295pa(-30mmH2O) Type A: +355pa (+36mmH2O) -295pa (-30mmH2O) Type B: +980pa(+100mmH2O) -295pa(-30mmH2O) Type B: +980pa (+100mmH2O) -295pa (-30mmH2O) Type C: +1950pa(+200mmH2O) -295pa(-30mmH2O) Type C: +1950pa (+200mmH2O) -295pa (-30mmH2O) Type D: according to user requirement (special pressure rating)
