Welcome to consult us.

General Twin Seal Valve

General Twin Seal Valve or  double bleed and block plug valve (DBB plug valve in short) is also called  general valve, expanding plug valve etc. With longer service life, small torque, easy maintenance, low cost etc. advantages, twin seal valve can be used in aviation kerosene, light oil, natural gas, liquefied gas, pipeline gas, chemical medium and other pipelines. AFC general twin seal valve has similar quality with those famous brands but more competitive price. 

 General Twin Seal ValveGeneral Twin Seal Valve main structural features:

1. High integrity positive shut-off obtained independent of line pressure, without sealants/ lubricants, Mechanical sealing ensuring     online-verifiable positive double isolation for critical services

2. Patented operator mechanism enables segments to move towards the seats during valve operation - reduces wear and tear          and enhances service life.

3.  Inbuilt cavity pressure relief system.

4.   Inline Maintainable Seats -Seats can be renewed without removing the valve from the pipeline (after draining and isolating the  line)

Application:

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.   With high quality and excellent service, AFC TECH valves are widely used Oil & gas industry, refinery & petrochemical industry, off shore, power generation, mining industry, pulp and paper, water treatment etc.
