進口油用安全閥品牌德國洛克LOCKE-A20

一、進口油用安全閥描述:

德國《LOCKE》洛克進口油用安全閥是一種用于石油，煤油，原油，重油介質(zhì)的壓力管道及容器作為超壓保護裝置，采用不銹鋼成形波紋管，保證介質(zhì)零外漏，又可平衡安全閥出口的背壓，保證整定壓力的準確性。

Locke oil safety valve is a kind of pressure pipeline and container used for oil, kerosene, crude oil and heavy oil medium as overpressure protection device. It adopts stainless steel shaped bellows to ensure zero leakage of medium, balance the back pressure at the outlet of safety valve and ensure the accuracy of setting pressure.
