Dear Sir/Madam, I would like to express my congratulations on the continued prosperity of your company. I sincerely appreciate your exceptional support for our products. Our company has been striving for operational efficiency and rationalization; however, due to the soaring prices of crude oil, naphtha, non-ferrous materials, and the impact of exchange rates, it has become difficult to compensate for these challenges through corporate efforts alone. Regrettably, we will be revising the prices of our products as outlined below. We are committed to further cost reductions in the future. In light of these circumstances, we sincerely apologize for any inconvenience this may cause and kindly ask for your understanding and cooperation, taking into account the various factors involved. Sincerely, [Target Products] HS Valves in general [Revision Range] Approximately 10% for resin valves, 20% for brass valves [Effective Date] From shipments on October 1, 2025 For further details, please contact our sales representative. Thank you for your understanding.

The improvement in workability due to weight reduction has been recognized as a new technology by the Ministry of Land, Infrastructure, Transport and Tourism! It has a mass that is one-third that of conventional steel flanges while maintaining sufficient strength. Its excellent workability leads to a reduction in the number of workers required, making it a cost-effective product. The astonishing lightness, which can be easily sent via courier, is a must-see.
