GMK Orbit Plug Valve / DBB PLUG VALVE

Orbit plug valves are utilized in a wide variety of industries, including the oil and gas sector, the chemical and fertilizer sector, the power sector, and many others. The product is attractive and functional in design as well as being of high quality. The rings of seals that surround the disc of the valve are what actually do the sealing. Wallow-tailed sink and fixed sealing rings provide specialized protection.

It’s easier to set up and use than similar products because of its unique bidirectional flow. To accommodate a wide range of technical requirements, we offer a wide range of part materials and flange sizes that can be reasonably configured based on actual operation conditions or customer specifications. When fully open, the valve’s plug channel lines up with the valve body’s, allowing for the most efficient pressure drop possible. When the handwheel is turned, the plug rotates in the direction of closure while simultaneously drafting the valve disc’s rotation by 90 degrees; when the handwheel is turned further, the plug is pressed down, causing the valve disc to open on both sides, bringing it into close proximity with the valve seat. First, the plug moves upward, separating the valve disc from the valve seat; then, when the handwheel is cranked further, the valve disc is rotated by 90 degrees, driven by the plug, and lastly, the plug’s channel lines up with the valve body’s channel, fully opening the valve. The soft seal applied for sealing ensures that there will be no leakage in the process of shutting the valve, and the separation of the valve disc and valve seat means that there is no friction and, consequently, no abrasion of the sealing face during opening and closing.

DESCRIPTION

Benefits:

  • The GMK Orbit Plug Valve or DBB Plug Valve design’s performance benefits lessen plant downtime and cut costs over the lifetime of the facility.
  • The Sweet Spot for Optimal Flow Whether the port is fully open or partially open, the CV will be high.
  • Erosion is mitigated and pumping efficiency is increased.

Method of operation

  • The hand wheel is turned, the plug will rotate toward the closing direction, and at the same time draft the rotation of valve disc by 90 degree;
  • When the hand wheel is turned further on, the plug will be pressed down, and make the valve disc open to two sides, so that the valve disc will be in firm contact with the valve seat and close the valve. When the hand wheel is turned inversely, first of all the plug will move upward, and the valve disc and valve seat will be separated;
  • If the hand wheel is turned further on, till the valve dics is truned by 90 degree driven by the plug,and finally the channel of plug will be in alignment with the channel of valve body, so that the valve is be fully opened.

 

The advantage of this type of valve is,during the opening and closing of valve,the valve disc and valve seat is separated,and there is no friction and thus sealing face is no abrasion in the process;at the same time, soft seal is applied for selling,so that there will be no leakage in the process of closing.

Feature

  • The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance
  • Its sealing realized by the sealing rings around the valve disc. It has unique protection of wwallow-tailed sink and fixed sealing rings
  • Its characteristic double-direction fliow makes installation and use more convenient
  • The materials of the parts and sizes of flanges can be reasonably configured according the actual operation condition or the requirements of the customers,so as meet the various needs of engineering
  • When the valve is fully opened, the channel of plug is in alignment with the channel of valve body, which can ensure ideal and lowest dercrease on pressure

FUNCTION AND APPLICABILITY ANALYSIS OF DOUBLE BREAK AND BLEED VALVE (FULL BORE]

Introduce a double block and bleed valve’s structure and working principle.The valve is superior to common gate and ball valves in terms of its sealing performance and service life.The valve has the functions of being fireproof, on-line maintenance, double block and bleed, cavity pressure relief, internal leak detection and others. Illustrate the double block and bleed valve’s functions and applications in the oil and gas storage and transportation systems in combination with examples, which has opened new development potential for process design of oil and gas storage and transportation systems and solved many problems encountered in pipeline design. It has not only optimized the pipeline design and improved the product quality but also saved the pipeline operation costs.
