Pneumatic flanged butterfly valves operate with pneumatic actuators.
At present, the flange butterfly valve of our Hongxin valve is flanged. In the new series of GT-type pneumatic actuators, the GT-type pneumatic actuators are double-acting and single-acting, using a safe and reliable butterfly valve for gear transmission. In the large-diameter flanged butterfly valve, a series of pneumatic actuators are used for the fork-type transmission. The design is reasonable in structure, large in output torque, and double-acting and single-acting. More conducive to the use of customers.
Pneumatic flange butterfly valve design standard: GB/T2238-1989 Flange connection size: GB/T9113.1-2000; GB/T9115.1-2000; JB78 Structure length: GB/T12221-1989 Pressure test: GB/T13927-1992 ;JB/T9092-1999
The flange butterfly valve is composed of a rubber sealing butterfly valve and a carbon steel or stainless steel valve plate and a valve stem. It is suitable for the regulation of flow rate and intercepting medium on the water supply and drainage and gas pipelines of temperature ≤120 °C such as light textile, paper, food, medicine, chemical, petroleum, electric power, etc. Its main features are:
1. The design is novel, reasonable, unique in structure, light in weight, and quick to open and close. 2, the operating torque is small, easy to operate, labor-saving and smart. 3, can be installed in any location, easy to maintain. 4, the seal can be replaced, the sealing performance is reliable to achieve two-way seal zero leakage. 5. The sealing material is resistant to aging, corrosion and long service life.
Below we Hongxin valve to analyze the first use and material introduction of the flange butterfly valve.
The choice of flange butterfly valve material, strive for stainless steel valve stem, large diameter valve should also be stainless steel embedded valve stem. The material of the stem bushing should be no more than the valve stem, and it will not form electrochemical corrosion with the valve stem and valve body under water immersion conditions. Nut material, cast aluminum brass or cast aluminum bronze, and the hardness and strength are greater than the valve stem. Flange butterfly valve material, because gray cast iron pipe is gradually not recommended, the valve body material should be mainly ductile iron, and indicate the actual physical and chemical test data of the grade and casting.
1. Gear type double piston, large output torque and small volume. 2. Manual operation mechanism can be installed at the top and bottom. 3. The IS05211 standard connection provides convenience for the installation and replacement of the product. 4. The actuator can be equipped with electric signal feedback indication and various accessories for automatic operation. 5. The cylinder is made of aluminum and gold materials, which is light in weight and beautiful in appearance. 6. The rack-and-pinion connection can adjust the opening angle and rated flow. 7. The joint screws adjusted at both ends can make the standard product have an adjustable range of ±4° at 0° and 90°. Ensure synchronization with the valve.
Accessories options The following accessories can be selected according to different controls and requirements: cut-off type accessories: single electronically controlled solenoid valve, double electronically controlled solenoid valve, limit switch returner. Adjustable accessories: electrical positioners, pneumatic positioners, electrical converters. Air source treatment accessories: air filter pressure reducing valve, air source treatment triple piece.
