双联球阀(并联球阀、串联球阀)在管道需要切断时,只需要转动其中一个球体对管道进行切断,另一个球体只有在该球体的阀座密封组件失效后才动作。也可交替动作两个球体使本产品的使用寿命更长,对管线使用达到双保险、双切断作用。两个球阀一体成型,不需要在安装时临时调试两个球阀的流量中心线,也减少了两个球阀直接串联安装中的一个连接点和一个泄漏点,安全可靠。双开关球阀。
产品用途:自贡自泵球阀厂生产的双联球阀是由两个普通球阀所组成,这两个球阀连为一体,且共用一个进口端。本双联球阀可以满足同一处需要两个出口端的要求,且每个出口端能独立控制,具有结构简单、操作方便的的性能及优点,可广泛应用于管道特别是煤气管道上。

API6D double block and bleed (DBB) twin ball valves
Please inform us of the accurate nominal size, pressure class, medium, temperature, material, actuator and other parameters, before consulting or purchasing the product. Thanks!
The double block and bleed ball valve is composed of two common ball valves, which are connected as a whole and share one inlet end. The double ball valve can meet the requirements of two outlet ends in the same place, and each outlet end can be controlled independently, with the performance and advantages of simple structure and convenient operation, which can be widely used in pipelines, especially gas pipelines.
The two balls are integrally formed, so it is not necessary to temporarily adjust the flow center line of the double block and bleed valve during installation, but also reduces connection points and leakage points in the direct installation of the two ball valves, which is safe and reliable.
Product advantages:
1. Double cut off, safe and reliable.
2. Simple structure and convenient operation.
3. Quadruple seal, reliable seal.
4. Product Name: double block and bleed ball valve
5. Nominal Pressure: Class 150~Class 2500LB (PN16 ~ PN420)
6. Nominal Diameter: 2 "~ 36" (DN15 ~DN900)
7. Applicable Temperature Range: - 20-250 ℃
8. Applicable Media: water, oil, gas and some corrosive liquids (W.O.G)
