? 材質(zhì)：不銹鋼、銅

? 公稱壓力：50MPa

? 公稱流量：2000L/min

? 此安全閥為全新設(shè)計(jì)的產(chǎn)品，采用兩級(jí)泄液的方式，當(dāng)壓力超過(guò)設(shè)定壓力不多時(shí)，可由一級(jí)泄液進(jìn)行泄液。當(dāng)壓力超過(guò)較大，一級(jí)泄液滿足不了時(shí)，一二級(jí)泄液同時(shí)打開(kāi)，流量可達(dá)2000L/min。

? Material: stainless steel, copper

? Nominal Pressure: 50MPa

? Nominal Flow: 2000L/min

? This safety valve is a newly designed product with two-stage discharge. When the pressure exceeds the set pressure for a little while, the first stage discharge can be used for discharge. When the pressure exceeds a large amount and the first-stage discharge cannot meet the requirements, the first-stage and second-stage discharge can be opened at the same time and the flow can reach 2000L/min.
