Drop In Type Check Valve - China

price: contact company for price

Retrievable Drop-In Check Valve provides a means of

controlling back flow through the drill pipe during a kick

or when tripping pipe into the hole against pressure.

The landing sub is installed in the drilling string, usually

just above the drill collars. The valve is kept on the

surface until protection from back flow is required. The

valve is introduced into the drill string and pumped down

the drill string to the landing sub where it locks into

position.

Features: Pressure from below the landed valve energizes

the packer, lock dogs and check valve. The check valve will

open to allow circulation through the valve and

automatically close when circulation is stopped. After use,

the back pressure valve can be retrieved from the string

with the retrieval tool run in on wire line.

Specifications:

The landing sub body is manufactured from 4145 heat-treated

and stress relieved material. Sizes not listed available on

request.

Non-Retrievable Drop-In Check Valve operates in a similar

manner as the retrievable valve, with the exception that

once the valve is landed in the sub, it is not possible to

retrieve it on wire line. The valve must be removed on the

surface.

Features: Pressure from below the landed valve energizes the

packer, lock dogs and check valve. The check valve will open

to allow circulation through the valve and automatically

close when circulation is stopped.
