Cast iron double orifice kinetic air valve
Product Description:
I. Application of QB2 double-port exhaust valve:
P2,QB2 double-port (inlet) valve is suitable for the pipeline with industrial medium as water, and it is necessary for the pipeline to remove the gas in the pipeline quickly to improve the efficiency of the water conveying equipment and to protect the pipeline from deformation and rupture.
II. Features of QB2 dual-port exhaust valve:
1. can remove the gas in the pipeline and reduce the resistance to save c source.
2. when the pipe negative pressure, this product can quickly and automatically inhale air to prevent pipe rupture.
3. exhaust capacity is more than double hole exhaust valve.
4. float bracket is stainless steel, long service life, safe and reliable.
III. QB2 performance technical parameters of the double-port exhaust valve:
1. media: clear water
2. temperature: room temperature
3. shell strength test pressure :1.5 MPa, no damage.
4. float seal test pressure :0.05∽1.1 MPa No leakage
5. body material: gray cast iron HT200 6. float bracket: stainless steel
