What is a Lift Plug Valve?

The original lift plug valve, invented by SchuF in 1914, is a simple and clever design incorporating the first double block and bleed mechanism. Today, the Lift Plug Valve is widely used in the Chemical, Refinery (including Delayed Coking, Hydrocracking, and Visbreaking), Polymer, Cement, Power and Mining industries.

What are the benefits of Lift Plug Valve designs?

Lift Plug Valves are specifically designed for severe applications that deal with high temperatures, fluids and suspended solids. They have:

Protected Valve Seat (PVS)

Total Sealing between body and plug ensures clean cavities

Flushing and/or Purging only during operation

Double Block & Bleed

Optional flushing valve to flush out any debris above the plug

Bottom entry, 3 or 4 outlets in T (90°) or Y (120°)

How does a Lift Plug Valve work?

Lift Plug Valves have many designs, but generally, a Lift Plug Valve has two seals with a mechanism that rotates between open and closed positions that protects both seals from the flow path. To operate a Lift Plug Valve, raise the plug when it is opened and rotate the plug 90 degrees to fully open the valve to reduce friction. To close the valve, turn the plug 90 degrees again to the closed position and then lower it to seal the body seat and seal together. The seals come in either soft seals or hard seals depending on the application. To buy the right Lift Plug Valve for your application, contact one of our valve experts today.

What are the different types of Lift Plug Valves?

High-temperature Lift Plug Valves are commonly used in oil and petroleum refining, petrochemical, chemical and energy industrial applications.

Double Seal Lift Plug Valves

is a cylindrical plug with three plates that have soft-sealing structures. This valve also provides Double Block and Bleed functions.

What are typical uses of a Lift Plug Valve?

Lift Plug Valves are commonly used in chemical and petrochemical applications, especially for highly-erosive fluid applications such as slurries particularly at high temperatures. These valves are used in Refineries, Coker units, FCC (Fluid Catalytic Cracking), Ethylene Plants and other chemical and petrochemical industrial applications.
