KTNQPB347F Pigging Valve Pigging Valve product details

KTNQPB347F Pigging Valve Product working principle and purpose:

KTNQPB347F Pigging Valve produced and sold by Baigang valve group is a new type of valve that is mainly used for cleaning pipes in long-distance pipelines such as water, petroleum, natural gas and the like for transmitting and receiving pigs. With the corresponding pig can easily complete the pipe cleaning, emptying and in-sequence delivery of media, testing pipeline systems and other work. Can completely replace the traditional use of the pig to send and receive tube as the core complex pig launching and receiving devices. The structural features of the pigging valve is a new type of valve that is innovatively designed after retrofitting and adding functions based on the principle of a fixed ball valve. Fully inherited the performance characteristics of two truncated ball valves, valve opening and closing through the 90 ° rotation of the core, easy to design double block and bleed to make the valve fully open or fully closed Can discharge the body cavity of the media, this function is necessary for the pig valve.

The side of the valve body is provided with a branch pipe whose center is perpendicular to the center of the pipeline. The quick-opening blind plate and the venting valve are arranged on the branch pipe so that the pig can be conveniently inserted into or removed from the pigging valve. The larger one of the through holes is provided with a blocking bar which can hinder the passage of the pig and allow the medium to flow through.

100% pressure test to ensure no visible leakage at any sealing site; Fire-resistant safety design with metal-to-metal seal between ball valve seat and valve seat when the flexible seat is burned; Both valve body and bonnet and stem part Set high temperature graphite gaskets, to ensure high temperature sealing reliability, fire test in line with API 6FA and API 607 standards; anti-static design, guided electrostatic springs to ensure good communication between the ball, stem and valve body, safely export friction Static electricity.

KTNQPB347F Pigging Valve Product Structure Features:

1, top-mounted valve body design to achieve on-line valve maintenance
2, the stem from the ball thrust, stem torsion freely, flexible valve operation
3, quick open blind easy to operate
4, zero leakage
5, interlocking design to ensure that the operator Safety
6, fire safety design, fire test in line with AP, 6FA and AP, 607 standards
7, anti-static design
8, cleaning design
