Product Features
The structure is easy to install and saves costs.
The closing pressure difference is large and the closing is tight.
The water flows straight through and does not block the residue. The KVS value is much larger than the general two-way valve.
The valve opens flexibly and can effectively prevent water hammer.
FAQ
1. What are the advantages and disadvantages of electric brass ball valves compared with stainless steel ball valves?
Electric brass ball valves are usually more cost-effective, have good thermal conductivity, and are suitable for medium and low pressure occasions. Stainless steel ball valves have higher corrosion resistance and strength, and are suitable for high pressure or corrosive media occasions. Brass ball valves are widely used in homes and water supply systems, while stainless steel is often used in industrial environments.
2. Can motorized electric brass ball valves be used in hot water systems?
Yes. Brass has good thermal conductivity and high temperature resistance. Electric brass ball valves can be used in hot water systems and can usually withstand water temperatures up to 120°C.
3. Is the electric brass ball valve suitable for corrosive media?
Not recommended. Brass may corrode in some acidic or corrosive media. If corrosive fluids need to be controlled, it is recommended to use stainless steel or corrosion-resistant material ball valves.
4. What is the pressure range of the motorized electric brass ball valves?
The pressure range of the electric brass ball valve is usually between 1.0-2.5 MPa, which is suitable for medium and low pressure pipeline systems. The specific pressure resistance depends on the model and valve design.
5. Will the electric brass ball valve maintain its current state when the power is off?
The standard electric brass ball valve will maintain its current open and close state when the power is off. However, some models are equipped with an automatic reset function, and the valve will return to the preset position after the power is off.
