Min Order: 1
FRICK butterfly valve is an isolating valve for both liquids and gas application. The butterfly valves is designed with a slightly double eccentric shaft, when initiating the rotary opening movement, the seat ring will be off-seated after only a small degree, which ensure the sealing ring is unstressed and lower wear.

The butterfly valves cover a large range of sizes and pressure. Temperature limits for water 100 degree; , for steam 120degree; ( other media upon to request).

The flange body is made of SG iron and fabricated steel and can be design to meet a variety of standards. The bearings and sealing of the shaft journal are practically maintenance free.

As a result of more than 30 years experience in butterfly valves manufacturing field, all the resilient-seated butterfly valves will be sealed in bi-direction under the sealing pressure 1.1 times of valves normal pressure.

Pressure Rating: PN 0.25-2.5 MPa
Nominal Sizes: DN150-3000mm
Unique features of our butterfly valves
High anti-corrosive fusion seat with ductile iron body
Thanks to the continues research and development, FRICK becomes one of the several valve suppliers who take advantage of the advanced plasma welding in ductile iron butterfly valve manufacturing process. This advanced technology makes the valves body and seat integrative, seat made of nickel based alloys, which provides the valves much longer service lives shown in the following points:
High anti-corrosive seat with material of nickel
Based alloys, available for a wider mediums purpose.

Due to the fusion seat with body, the adherence strength between body and seat are much more reliable than any other mechanical joint methods, the seat will never loose from the body.
Flying-disc-shaped disc ensure the valves have very low flow head loss comparing to other ordinary disc design.

As a result of more than 30 years experience in butterfly valves designing and manufacturing, FRICK engineer know "Freely Operation", "High Anti-corrosion" and "Shut off for bi-direction" will never be the total for the best butterfly valves, "Low Head Loss" will play a very important role for pipe system. "Low Head Loss" is now and will be continues required by more and more intellect customer, for the more efficient economy, and also for better environment.

For valves size from DN150 upon to DN1200, all the disc will be designed to a flat shape. For valve size DN1200 and above ( only for valves made of ductile iron), the butterfly valve disc will be designed to a flying-disc shape, which will ensure the valves have very low head loss comparing to other ordinary design.

Materials of the butterfly valves
BDOY: GGG40, WCB, CF8, CF8M.
DISC: GGG40, WCB, CF8, CF8M.
SHAFT: SS410/420, SS304. SS316, 17-4PH

Field of application
In water supply system for the isolation of pipes carrying potable water, sewage ad sea water
In chemical Engineering for isolating all kind of liquid and gaseous media
In power Stations for cooling water and condensate pipes
For irrigation schemes
In air conditioning and ventilation plant
Euipmented with high performance electro-hydrulic system, FRICK butterfly valves will serve as combined chech valve (Isolation non-return valve with electro-hydrulic actuator), which will be assemblyed at the outlet of the pump for the safety of the pump and pipe.
Prod Model: 2300 series
Suzhou Frick Trading Co., Ltd. (to be called as FRICK) which is located in Suzhou, is premium industry valves suppliers and a leading valve manufactures in China.

Thanks to continues research and development, FRICK has succeed to supply the domestic and international market variety valves such as: Stainless steel Penstock, High-performance Triple Eccentric Butterfly Valves, Double Eccentric Half Ball Valves, Fast-close Valves for nature gas, different kind of check valves, resilient-seated gate valves and so on. Products cover a range from DN15 to DN2800mm, the highest nominal pressure up to 25.0MPa. The standards for the valves include API, JIS, DIN, EN, BS and our Chinese national standard GB. Now we have 6 professional factories to support the above the products.

All the above products are quality guaranteed, which take back a great deal praise and applause for us. As a result, FRICK has plenty of customer in Europe, American, Asia and Australia, also have good corporation to China main steel company such as Bao Steel, Peking Steel, Wuhan Steel and so on.

Currently, The goal of the Company is "to create value for users", All the employees of FRICK are striving and will also in the same way in the coming days to establish a long relationship for mutual benefits with the customers.
