Double block&bleed ball valve


Double block & bleed ball valves are designed to replace the multiple valve connections in traditional pipelines. It reduce the leakage point in the system,save installation space and reduce the pressure of the pipeline system. So, this type valevs are widely used in power, petrochemical, metallurgical. marine, petroleum, natural gas, gas, pharmaceutical and other industries in the hydraulic system pipeline. 

Double block & bleed ball valves are mainly suitable for the instrumentation but is also required as an alternative to the in-line installation of two valves. They can be supplied both in the Trunnion and in the Floating version.
