Detailed Introduction

 Forged steel ball valve

Unique feature and use

1、Anti-curing stress cracking:The valve contact medium's material is corrodes Engineer according to the US the association NACEO1-75 standards to carry on the choice,and carries on the superficial nickel plating according to the standard,can satisfy the curing environment operating mode the request.

2、Make the packing material with the polymer or the metal,in the high temperature,the high-pressured operating mode has the fine sealing property.

3、The establishment stuffing box,prevents the valve cavity pressure anolmaly to elevate causes the valve lever to depart,increasess ets seals the structure but actually,can guarantee that the padding seals reliably.

4、 Widely is suitable for medium pipelines and so on chemical industry,refinery,oil gas,natural gas,steel and iron.


Implementation of standards

1、Design and manufacture: GB/T 12237-1989;API608

2、Inspection and test:GB/T 13927-1992; API598

3、Fnge connection:GB/T 79.1~4-1997;ASME/ANSI B16.5

4、Structure length: GB/T 12221-1989;GB/T 15188.1-1994; ASME/ANSI B16.10
