Are you struggling with "clogging" in agricultural water? [Latest video released☆]

Are you struggling with "clogging" in agricultural water? [Latest video released☆]

More 'ease' on site. Meiwa Kogyo's agricultural air valves improve clogging issues and eliminate troubles, reducing the burden of work.

The agricultural air valve smart air valve is a high-performance air valve optimized for agricultural water. Generally used air valves for water supply systems face challenges in maintenance management due to malfunctioning intake and exhaust operations and poor shut-off caused by debris and sediment mixed in agricultural water. This agricultural air valve prevents the adhesion of debris mixed in agricultural water through a new structure that keeps the valve seat submerged, resolving issues of water leakage, malfunction, and poor shut-off. Furthermore, it significantly reduces maintenance costs. We have just released a new introduction video. Please check it out☆ 【Reasons for Choosing the Smart Air Valve】 ■ Unique structure prevents adhesion of debris and sediment, resolving water leakage and operational issues ■ Significantly reduces maintenance frequency ■ Made of corrosion-resistant stainless steel material to prevent functional failure due to corrosion ■ Compatible with various installation conditions such as water pipe bridges and buried sections 【Registered as Made in Niigata Gold Technology!】 This new technology has a proven track record among registered technologies and has been utilized in construction projects ordered by Niigata Prefecture and others, resulting in an evaluation by an expert committee that it is "more effective than conventional technologies."
