FAQ
Q: What is the company's production capacity? Can it meet the delivery needs of large-scale orders?
A: We have a modern production base and advanced equipment, and multiple automated production lines operate in coordination. With a complete production scheduling and supply chain management system, we can flexibly allocate resources according to the order volume, and ensure that large-scale orders are delivered on time and with high quality.
Q: How is the reliability of the product guaranteed under different working conditions? For example, high temperature or high humidity environment.
A: During the design and production process, we conducted rigorous tests for different working conditions. For high temperature environments, the product can withstand a fluid temperature of 95°C; for high humidity environments, it is specified that the ambient temperature is 0-65°C and the maximum relative humidity is non-condensing. From material selection to manufacturing process, multiple rounds of optimization have been carried out to ensure that the product operates stably and reliably under various working conditions.
Q: How is the reliability of the product guaranteed under different working conditions?
A: Our valves are strictly controlled from the selection of materials, such as forged brass for the valve body, stainless steel for the valve stem, and EPDM for the sealing material. The production process follows a strict quality control system, and each process has professional quality inspection. And the product has been rigorously tested to simulate different working conditions to ensure stable and reliable operation in your actual use scenario.
Q: What are the advantages of your company's products compared with similar products on the market?
A: Compared with similar products, our valves are better in materials, using high-quality forged brass valve bodies and stainless steel valve stems, with strong corrosion resistance and long service life; the sealing material EPDM ensures good sealing effect and reduces the risk of leakage. In terms of performance, the travel time is short, the motor torque is large, the pressure is up to 1.6MPa, it can adapt to a variety of complex working conditions, and it is more cost-effective.
