ZZYP-II指揮器操作型自力式壓力調(diào)節(jié)閥
ZZYP-II Pilot Regulator Operation Type Self-Operated Pressure Regulator
ZZYP-II指揮器操作型自力式壓力調(diào)節(jié)閥主要用于壓差較大的場(chǎng)合，閥前后壓差≥0.1Mpa.特別適用于氮封裝置中供氮閥用，壓力設(shè)定點(diǎn)在0.1~2000kpa。
ZZYP-II Pilot Regulator Operation Type Self-Operated Pressure Regulator is mainly used for differential pressure larger occasions,before and after the valve pressure difference acuity 0.1 Mpa.Especially suitable for nitrogen sealing device for the nitrogen valve,pressure set point in 0.1~2000Kpa.
