The AWWA C504 valve with a metal seal on the butterfly valve generally has a longer life than a valve with an elastic seal. But it is difficult to achieve a complete seal. Metal seals can accommodate higher operating temperatures, while elastomeric seals are temperature-limited. Commonly used butterfly valves are wafer-type butterfly valves and flange-type butterfly valves. The wafer-type butterfly valve uses a stud bolt to connect the valve between the two pipe flanges. The flange-type butterfly valve has a flange on the valve, and the flanges on both ends of the valve are connected to the pipe flange by bolts.
AWWA C504 butterfly valve structure features:
1. The unique design of the three-way eccentricity achieves the frictionless transmission between the sealing surfaces and prolongs the service life of the valve.
2. Elastic seal is produced by the torque.
3. Ingenious wedge design makes the valve seals aromatically, with compensatory and zero-leakage between sealing surfaces.
4. Small in size, light in weight, and easy to use and install.
5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
6. Diversified continuous structure: clamping, flange, butt-welding.
AWWA C504 butterfly valve:
1. For the gas pipeline in the sulfuric acid industry: the front and rear blower inlet and outlet, the relay fan inlet and outlet, the electric defogging series and the connecting valve, the S02 main blower inlet and outlet, the converter adjustment, the preheater inlet and outlet, etc.
2. It is the preferred brand for the sulfur sulphuric acid plant valve used in the sulfur sulphuric acid system. It is considered by the majority of users as: good sealing performance, easy operation, anti-corrosion, high temperature resistance, convenient operation, flexible, safe and reliable. It has been widely promoted.
3. Also widely used in: chemical, petrochemical, smelting, medicine, food and other industries in SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid It is used as a regulating and shut-off device in the pipeline of medium such as phosphoric acid.
