Back pressure valve


Back pressure valve  

Back pressure valve is designed to be used as a part of the wellhead equipment to maintain pressure between pipelines and to prevent back flow of the fluid.

It allows to perform work within operating pressures from 0 to 35MPa (KO1) due to the use of the special sealing.

Absence of free spaces eliminates the possibility of freezing. Hydraulic characteristics have been proved.

Main check and control elements are made of corrosion resistant steel. Use of the ceramic guide bushing provides safe operation of the back pressure valve during service life.
