Vacuum-Proof Lining Flange Plug Valve with Chemical-Resistant

Structural Features
The vacuum-proof lining flange plug valves have commonly been used for primary and secondary tight shut off, in an attempt to provide and ensure system integrity. Previously, the system integrity needed two individual isolation valves, a spool piece and a bleed valve that not only caused extensive costs and weight but also were increasing the risk of emissions due to multiple flanged faces.
These DBB plug valves have a single body with dual Plug valves with a bleed valve installed between the two main line valves and are available bi-directional with metal seat or rubber seat, both in ANSI Class VI.
They replace existing traditional techniques employed by pipeline engineers to generate a double block and bleed configuration in the pipeline.Actuators, gear boxes and extended handles can be offered for these valvesCryogenic and high-temperature applications are availableSoft or metal seatedStructural information .BB-BG-OS&YDiving mannerHandwheel, bevel gear wrenchDesign standardAP1599, API6DFace to faceASME B16.10Flange endASME B16.5Test&inspectionAPI598,API6D

1. Competitive Price & On-time Delivery, with Integrated Services
Valves serve a variety of purposes in the industrial, engineering, manufacturing and scientific communities. Selecting the right valve can determine the success or failure of the system or process.
The main purpose of a valve is to control media flow through a system. The valve may be used to start, stop, or throttle the flow to ensure safe and efficient operation of the process. Valves play a large role in most industries.
