Advantages of a Butterfly Valve | feidavalve.com

High performance butterfly valve

Butterfly valves are similar to ball valves but have several advantages. They are small and, when actuated pneumatically, open and close very quickly. The disc is lighter than a ball, and the valve requires less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and require very little maintenance.

FEIDA is specialized in High Performance Butterfly Valve for more than 15 years. There are 2 main facilities includes 2 valve assembly & testing factories, 1 large CNC machinery plant, 1 investment casting foundry (3000T/Y) and 1 valve R&D center, equipped with most advanced production equipment and testing equipment.

Thefire safe butterfly valveis also in FEIDA VALVE product range. Our fire safe butterfly valve is certificated by American Petroleum Institute (API) according to API 607 standards.

FEIDA also build up a dustless workshop to produce ultra-clean valve for some critical working condition such as nuclear industry, semiconductor industry etc.

In the dustless workshp, FEIDA also produce the food-grade valves.FEIDA food-grade valveis certificated by Food and Drug Administration (FDA).

The bonds between PSA(Pressure Swing Adsorption) and High Performance Butterfly Valve

图片
  High performance butterfly valves ： Generally refers to  double eccentric butterfly valve  and  triple eccentric butterfly valve ,due to their excellent working performance and high sealing ability (compared with concentric butterfly valve) are widely used in petrochemical,power plants,metallurgy,civil heating fields.Eccentric butterfly valves have the good working performacne to meeting sever and strict requirements in many different industries.Today, we are going to introduce the application of eccentric butterfly valve in air separation for making oxygen,hydrogen,CO etc. At present,the mature air separation system is PSA(Pressure Swing Adsorption),it need certain number of programmed valves (valve parts usually double or triple eccentric butterfly valve) in its pipeline system to control and adjust the medium. FEIDA  double (and tripple) eccentric butterfly valve are widely used in this kind of PSA system due to the valves' excellent features: 1-Long service life,on-off 1 mill

What is difference about zero, double and tripple offset butterfly valve?

图片
Choosing the wrong type of valve can be detrimental to your operation. There are a few different types of  butterfly valves  on the market, including the zero offset, double offset, and triple offset. Zero Offset Also known as a concentric design, this is common in general service ‘resilient seated’ or ‘rubber seated’ butterfly valves. The stem and disc are centered in the seat of the valve, all of which are centered in the body of the valve. The disc is in constant contact with the seat. An advantage of this valve is the media going through the valve will not contact the body, since the seat is constructed as a sleeve or cartridge inside of the body. Zero offset butterfly valves are used in basic and specialty liquid and gas applications up to 200 PSI and up to 400 deg F. The zero offset butterfly valve can handle chemicals, coatings, food, some solids, and abrasive applications. The zero offset butterfly valve is available in epoxy coated cast iron and stainless ste
