V-ball valve pneumatic VQ647H
Product Name:
V-ball valve pneumatic VQ647H
Description:

名称:
气动V型球阀、 气动V型调节球阀
型号:
VQ647H
口径:
DN15-300
压力:
1.0-6.4Mpa
材质:
铸钢、不锈钢、铸铁、合金钢等
气动V型球阀、气动V型调节球阀采用圆柱型弹簧预载的带补偿性可动金属阀座结构,密封性能可靠。球芯与阀座不会产生卡阻或脱离,使用寿命长。
球芯上的V形切口与金属阀座之间具有剪切作用,特别适用于控制高粘度,含纤维、固体颗粒及浆料等介质。结构制造纸工业的纸浆显得尤为优越。
阀门的流通能力大、压力损失小、且介质不会沉积在阀体中腔,阀门不仅具有近似等有分比的流量特性、可调范围大,最大可调比为100:1,还具有精确调节与可靠定位的功能。
