Ductile Iron Butterfly Valve with Handle or Worm Gear Operated
Ductile Iron Wafer Centerline Butterfly Valve is a valve whose working principle is to use a circular butterfly plate to rotate around the valve stem to control the flow of fluid. The butterfly plate can be rotated between 0°~90°. When it is rotated to 90°, the valve is in a fully open state, and when it is rotated to 0°, the valve is in a fully closed state. The rotation angle of the butterfly plate can adjust the flow and pressure according to the needs. The valve body of this valve is made of ductile iron, which has good mechanical properties and corrosion resistance. This valve is characterized by easy installation, good sealing performance, compact structure, light weight and low price.
The scope of application of the ductile iron butterfly valve mainly includes the following aspects:
- It is suitable for conveying pipelines of non-corrosive media such as water and steam, and can adjust the flow rate and cut off the medium flow.
- It is suitable for food, medicine, chemical industry, petroleum and other industrial fields, where sanitation and high temperature resistance and high pressure resistance are required.
- It is suitable for public water supply and drainage, irrigation, ventilation and other projects where compact structure, light weight and convenient operation are required.
The precautions for ductile iron wafer butterfly valves mainly include the following aspects:
- Before installation, check whether the model, specification, pressure, etc. of the valve meet the requirements for use, and whether the arrow on the valve is consistent with the direction of fluid flow.
- The integrity of the valve should be maintained during installation, the seals and coatings should not be damaged, and no heavy objects or knocks should be placed on the valve.
- During installation, attention should be paid to whether the flange or wafer connection at both ends of the valve is firm, whether the sealing gasket is suitable, and whether the bolts are evenly tightened.
- After installation, a pressure test should be carried out to check the sealing performance and strength performance of the valve. The test pressure and time should be carried out in accordance with relevant standards.
- During use, the working status of the valve should be checked regularly, damaged parts should be replaced in time, and the valve should be kept clean and lubricated.
