VALVE

The special design stem bearing is design for high frequency operation to provide a durable & good sealing performance. It is combined with stainless steel tube and inner lining RPTFE. When the valve open/close, the inner lining RPTFE will be the lubricant to minimize operation friction and torque. Normally, the stem packing is made of graphite, but after a strenuous operation, the graphite will peel off, the peeled graphite chips will go into the flow-path to contaminate the flow media. Due to the high frequency operation (at least 2 operation/minute) requirement of gas industry valves, our stem bearing is a perfect design for  Gas Industry  especially the  Vacuum Pressure Swing Adsorption . 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 p

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

FEIDA  High Performance Butterfly Valves  are used in rigorous applications especially in the petrochemical and offshore settings. FEIDA design and engineered this high quality butterfly valves with a fire safe feature. Such feature typically incorporates a secondary sealing seat that will maintain a positive shutoff when the primary seal is destroyed in a fire. This secondary sealing seat is made of indestructible materials that can tolerate extremely high temperature. Fire safe butterfly valve models, just like other types of butterfly valves, are used not only for on/off function but also for control applications. In most cases, the primary seat of fire safe butterfly valves offers near zero-leakage assurance. The secondary metal seat can perform sealing function, but may allow minimal leakage at high temperature that occurs during fire. The main sealing seat is usually made of the material called PTFE (polytetrafluoroethylene) also known as Teflon. The primary seat is also res

The Exploded View of Solid Metal Seat Tripple Offset Butterfly Valve: 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. The  fire safe butterfly valve  is 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 valve  is certificated by Food and Drug Administration (FDA).

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.
