500X pressure relief / pressure valve held
Product Name:
500X pressure relief / pressure valve held
Description:

500X泄壓/持壓閥

500X泄壓/持壓閥王要用于消防或其他供水系統中,以防止系統超壓或維持消防供水系統的壓力。消防泵關閉后還可以減小水錘的沖擊。也用于大型供水系統的水錘消除裝置.并且閥門控制系統的進口處裝有一個自清潔濾網,利用流體特性,使比重較大、直徑較大的懸浮顆粒不會進入控制系統.確保系統循環暢通無阻,使閥門能安全可靠地運行。系統動作平穩、強度高、使用壽命長適用于600口徑以下的管道。
