Our patented products
The shower mixer valve on the market is mainly made of copper, but the copper connection is threaded connection, which has certain potential safety hazards. There is a risk of water leakage after being concealed in the wall for a long time. To avoid this risk, we have developed PPR shower mixing valve, which solves the risk of water leakage through welding connection. So far, we have developed PPR three-way mixing valve, PPR four-way mixing valve, PPR five way mixing valve, and PPR six way mixing valve, They have successfully applied for patents. At present, these products are mainly for export. Customers are very interested in these products and have been recognized by the market through trial orders.
