Murphy PD8100 Series Pulsation Dampener
MURPHY PD8100 Series脉动减振器


PD8100系列消除了压力指示仪表装置上的指针抖动,这些仪表装置受到往复泵或压缩机的脉动压力的影响。它还允许高、低触点的紧密设置,为设备提供更精确的压力指示和控制。PD8100系列通过消除过度的表压应变和不必要的移动,减少齿轮运动的磨损,提高压力指示仪表的寿命,这种必要性通过保护任何受到脉动影响的压力指示和控制仪表而迅速得到补偿。MURPHY PD8100 Series eliminates pointer flutter on pressure indicating gage devices which are subject to pulsating pressure from reciprocating pumps or compressors. It also allows a close setting of high and low contact points providing for more accurate pressure indication and control of equipment. The PD8100 Series decreases wear on geared movements and increases the life of pressure indicating instruments by eliminating excessive gage strain and unnecessary movement, a necessity which quickly pays for itself by protecting any pressure indicating and control instrument which is subject to pulsation.

PD8100 SERIES IS NOT FOR USE ON OXYGEN OR LIQUID OXYGEN APPLICATIONS.
PD8100系列不适用于氧气或液氧应用。

The PD8100 is quality built with a large diameter valve stem wheel for ease of adjustment and features clearly printed operating instructions.

Machined from 1 3/8-inch (35 mm) hex bar stock, a two degree taper on the valve and stem assure positive dampening.

It's available in brass, carbon steel, 303 stainless steel or 316 stainless steel to meet pressure and environmental requirements with either 1/2 NPT or 1/4 NPT inlet connections.
