多(duo)功(gong)(gong)能(neng)(neng)活塞(sai)控(kong)(kong)制(zhi)閥具有多(duo)種調(diao)節(jie)及(ji)控(kong)(kong)制(zhi)功(gong)(gong)能(neng)(neng)。如，水(shui)位(wei)控(kong)(kong)制(zhi)、減壓(ya)(ya)、止回、泄(xie)壓(ya)(ya)、流量(liang)控(kong)(kong)制(zhi)、以(yi)及(ji)壩底排空泄(xie)水(shui)等(deng)功(gong)(gong)能(neng)(neng)。最大進(jin)出口壓(ya)(ya)差可達40kg/cm2，尤其(qi)在大口徑、高(gao)壓(ya)(ya)力(li)和(he)大壓(ya)(ya)差的工況更顯現其(qi)優(you)越的調(diao)節(jie)和(he)控(kong)(kong)制(zhi)功(gong)(gong)能(neng)(neng)。

安裝在市政、建(jian)筑、石油、化工、煤氣(qi)(天然氣(qi))、食品(pin)、醫藥、電站、核電、水(shui)利及(ji)灌溉(gai)等領域的管(guan)路中，將較高的上游壓力(li)降為符(fu)合要求(qiu)的下游正(zheng)常使用(yong)壓力(li)。

多功(gong)能活塞控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥具有多種調節及控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)功(gong)能。如，水位控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)、減(jian)壓(ya)(ya)、止回、泄壓(ya)(ya)、流量控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)、以及壩底排空(kong)泄水等功(gong)能。最大進出(chu)口壓(ya)(ya)差可達40kg/cm2，尤(you)其(qi)在大口徑、高壓(ya)(ya)力和大壓(ya)(ya)差的(de)工況更(geng)顯現其(qi)優越的(de)調節和控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)功(gong)能。
