  • products details

YFL Double isolation plug valve is designed with two plug valves connected as one valve. Each plug valve has one pressure balanced inverted plug. Each pressure balanced plug valve can be operated independently or synchronously to realize different control requirements. The double isolation plug valve acts similarly as double block and bleed twin ball valve. 


The plug is rotated by 90° to open or close the plug valve. The open or close operation is fast and the operation torque is low. The oil sealing performance of the inverted plug valve is excellent and reliable.
