For our products which directly contact with drinking water, we pay utmost attention and use only the materials which are approved for use for various water supply (water fitting) regulations.

Water control valves: Our water control valves boast an impressive track record over many years about designing, and also more than 400tons of usage amount of PPS (Polyphenylene sulfide) resin in annual. We leverage on our expertise to cater to the specific requests of our customers. These valves that serve to control the flow of liquid (water, hot water, oil and etc.) are made from PPS (Polyphenylene sulfide) resin material, and differ from their metal counterparts as they are significantly lighter and are available at lower costs. If you wish to replace your metal valves with resin valves, please feel free to get in touch with us.

Heat exchangers: We have created the world’s first composite heat exchanger made from a combination of resin and metal which is unique and cost-effective. This heat exchanger can be installed in indoor unit of hot-water heating systems (Hybrid). As we also develop original heat exchangers according to the desired specifications of our customers, please feel free to get in touch with us.

PPS (Polyphenylene sulfide) resin joint: We convert metal fittings around a tank of hot-water heating (“Air to Water” mainly) to PPS (Polyphenylene sulfide) resin material. Taking advantage of the experience and know-how of PPS (Polyphenylene sulfide) resin molding over many years, we can make proposals according to your desired connection methods and shapes. Please feel free to get in touch with us.
