Kev txiav txim siab rau Kos Valve Xaiv

When selecting a check valve, factors such as media characteristics, operating pressure, temperature range, and installation space must be considered comprehensively. For example, for low-viscosity media (such as water), ball check valves are the first choice due to their low flow resistance and good sealing performance; while for high-viscosity media (such as oil), swing check valves with a wider flow channel design should be selected to reduce flow resistance. In addition, pressure rating is also a key parameter. Medium-pressure systems (such as 1.6-4.0 MPa) require check valves with stronger pressure resistance, while low-pressure systems (such as ≤1.0 MPa) can use more cost-effective ordinary check valves. Regarding temperature, media ≤120℃ can use check valves with fluoroplastic seats, while high-temperature media (such as >200 degree) yuav tsum tau kos li qub nrog cov rooj zaum hlau. Thaum kawg, qhov chaw installation yuav tsum tau txiav txim siab.
