Raws li qhov qhib, kaw thiab tswj cov cuab yeej ntawm qhov cua thiab cov kav dej tshem tawm plua plav, qhov cua npauj npaim valve yog qhov tsim nyog rau qhov cua, tshem tawm plua plav thiab kev tiv thaiv ib puag ncig hauv metallurgy, mining, cement, tshuaj lom neeg thiab kev tsim hluav taws xob.

Lub qhov cua npauj npaim valve raug ua tiav rau hauv lub nplhaib kaw nrog cov khoom siv zoo ib yam li lub cev valve. Nws qhov kub thiab txias siv tau nyob ntawm kev xaiv cov khoom siv ntawm lub cev valve, thiab lub siab nominal yog ≤ 0.6MPa. Nws feem ntau siv rau kev lag luam, hlau, kev tiv thaiv ib puag ncig thiab lwm yam kav dej rau kev ua pa thiab tswj cov dej ntws nruab nrab.

Nws cov yam ntxwv tseem ceeb yog:

1. Tsim qauv tshiab thiab tsim nyog, qauv tshwj xeeb, lub teeb yuag thiab qhib thiab kaw sai.

2. Me me ua haujlwm torque, yooj yim ua haujlwm, txuag zog thiab dexterous.

3. Cov ntaub ntawv tsim nyog yuav tsum tau siv los ua kom tau raws li qhov yuav tsum tau ua ntawm qhov kub qis, nruab nrab thiab siab thiab cov xov xwm corrosive.
