Forged Pig Valve

Description:

The pig valve is cleaned, the pipe will deposit or form dirt on the inner wall of the pipe during long-term use. These deposited dirt will deposit on the pipe wall and increase the fluid flow. resistance. Lay new pipelines, clean all kinds of residues in the pipeline before operation, and apply the rust-proof and anti-corrosion coating on the inner wall of the pipeline to make the pipeline unimpeded.

Usage:

PIG Valve is usually divided into two groups, one for the pig launch and the other for receiving. The PIG is used for receiving or launching depending on the upstream or downstream installation of the pipeline. 

The PIG valve has the closed position, so that the upstream and downstream (DBB) ball holes and the quick opening door are on one axis. 

PIG Ball valve cavity pressure to open the quick opening door, push the pig into the bottom of the valve cavity, then close the quick opening door, operate the opening position of the PIG, and the pig advances under the thrust of the medium. After the cleaning of the pig reaches the receiving PIG valve, the barrier fixed on the valve seat is blocked in the PIG valve cavity, and the PIG valve is operated to the closed position to double the upper and lower and middle chambers (DBB) and the quick opening door. On an axis. Exclude the PIG valve chamber pressure and open the door quickly to remove the pig.
