The double block and bleed plug valve contain two plug valves attached with the help of a small drain in the middle. It is fabricated for critical shutoffs methods where the complete shutoff is required for safety, environmental, or process reasons. This double isolation & bleed plug valve is lubricated.
Double block and bleed plug valves are sometimes deployed for critical tools such as:
Compressor isolation
Pump isolation
Metre isolation
Water/gas injection system isolation
Critical vents/drains/blow drains
Advantages of double isolation & bleed plug valve
There are many advantages of double isolation and bleed plug valve, such as:
As two valves are unified, expenses associated with installation and maintenance are decreased dramatically.
It is made of dynamic balance pressure and sealing technologies
Each valve is made according to the Standard NSI valve dimensions
Two seats of the valve ensure two times safety
Double isolation & bleed plug valve offers a maximum port area that improves the flow
Features of double block plug valves
A mechanical wedge action of a double block and deep plug valve is able to compress both the upstream and downstream seals against the body of the valve. It does not need any assistance from the line to affect a positive seal. While considering double isolation & bleed plug valve, you can get a tight mechanical seal both upstream and downstream.
Listed below are some useful features of double block plug valves:
Manual wrench using
Bare stem with mounting flange for actuation
Manual worm gear having vertical handwheels
Manual work gear having horizontal handwheels
Manual worm gear having vertical and one horizontal handwheel
These are some vital facts that you need to consider while choosing a valve for a plug. Take your time and pick the best product that can meet your requirements.
