Fisher™ DST-G Trim
費舍爾™DST-G TRIM是專為清潔或骯臟的服務(wù)而設(shè)計的,在這里流體有溶解氣體,這些氣體由于壓力的降低而從溶液中釋放出來(排出氣體)。出氣通常造成兩種類型的損害:空化和被流體流侵蝕。DST-G修剪階段壓降,類似DST修剪,以防止空化.侵蝕是由較低的保持架控制在這個修剪,它把水流分成較小的,較低的能量射流,不太可能造成損害。這種修剪也有能力通過微粒高達6.35毫米(1/4英寸)的直徑。

特點
Designed to control outgassing.
Has a pressure limit of 175 bar (2500 psi)。
The protected seat design separates the shutoff function from the throttling function to protect seating surfaces from throttling wear.
Hardened trim materials provide excellent wear resistance, resulting in long trim life.
Cage-type trim allows removal and inspection of parts without taking the valve body out of the pipeline.
The cage utilizes large slots to separate flow into smaller jets that are less prone to erode the valve body and generate vibration.
