FEIDAVALVE High performance butterfly valves are used in rigorous applications especially in the petrochemical and offshore settings. Most of these high quality double offset butterfly valves are designed with a fire safe feature. Such feature typically incorporates a secondary sealing seat that will maintain a positive shutoff when the primary RPTFE (reinforced polytetrafluoroethylene)seal is destroyed in a fire. This secondary sealing seat is made of high grade alloy materials that can tolerate extremely high temperature.

A butterfly valves with fire safe function is an important factor in ensuring safety and security in facilities. When butterfly valves without fire safe sealing fail during a fire incident, it can cause further damage to the pipework or the entire flow system, putting not only the environment in danger but also people's lives. This is the reason why fire safe butterfly valves units are highly suitable for handling hazardous and flammable fluids. This type of valve is also used for critical applications like hydrocarbon services, refinery services, steam control, liquor services, gas, and vacuum applications. In addition, fire safe butterfly valve models are commonly utilized in several industries like power generation, heating, ventilation, waste water treatment, food and beverage processing, pulp and paper production, shipbuilding and hydrocarbon processing.

An API 607 fire safe butterfly valve can have various body designs like wafer, lugged and double flanged. This type of butterfly valve is configured to withstand harsh conditions, extreme temperature rating and nominal pressure. The sizes and pressure rating of a fire safe butterfly valve are usually the same as any regular butterfly valves. Before the butterfly valve can be classified as "fire-safe", it should have undergone rigorous testing. There are a couple of tests that verifies the resiliency of fire safe butterfly valves, and they offer various methods and intensity level.

FEIDA VALVE is the top ranking China double offset butterfly valve manufacture. The annual output of high performance butterfly valve is more than 100,000,000 set.

The API 607 fire safe high performance 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 VALVE 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 workshop, FEIDA also produce the food-grade valves. FEIDA food-grade valve is certificated by Food and Drug Administration United States (FDA).
