The "A-89 type" is a strainer with a scraper that can discharge relatively large foreign objects without stopping the water, using the upper handle operation to release them through the drainage valve at the bottom of the main body. It features a large flow cross-section and smooth flow path, resulting in very low pressure loss. The drainage direction can be specified as desired, so please let us know your preference. 【Features】 ■ Can discharge relatively large foreign objects without stopping the water ■ Drainage direction can be specified as desired *For more details, please refer to the PDF materials or feel free to contact us.

This product is a safety valve that boasts excellent primary pressure retention performance with a large discharge capacity. It features an internal needle design that effectively prevents malfunction due to clogging, with a gentle closing action that is effective in preventing water hammer. In addition to its use as a safety valve, it can also be used as a primary pressure regulating valve. For more details, please contact us. 【Features】 ■ Excellent primary pressure retention performance with a large discharge capacity ■ Internal needle design ■ Gentle closing action effective in preventing malfunction due to clogging and water hammer *For more details, please refer to the PDF document or feel free to contact us.

• Piping Materials

The "Suppon Joint" is a flexible and expandable joint that does not disengage once pipes are connected. Traditionally, for the connection of piping in water supply, industrial water, and agricultural water, methods have been employed to make the entire piping system act as a single rigid body to ensure water tightness and prevent disconnection at the joint. As a result, enormous concentrated loads have been applied to the joint, leading to damage of the joint or pipes, which can cause leaks and other accidents, often resulting in decreased yield rates and social issues, requiring significant effort and costs for maintenance. This product is designed to eliminate these drawbacks. 【Features】 ■ Does not disengage once pipes are connected (grips tightly) ■ Pipes are expandable after connection (neck is expandable) ■ Allows for free bending at the joint (neck can bend up, down, left, and right) ■ Excellent water tightness (strong against water) *For more details, please refer to the PDF materials or feel free to contact us.

• Pipe Fittings

This product features a rational cylindrical shape, making it compact and lightweight, and it is an extremely easy-to-handle high-blow air valve for installation work. Due to the two-stage opening and closing mechanism with a floating valve body and a float valve body, there is minimal impact when closing, and the elongated floating valve body allows for smooth opening and closing along the guide, ensuring reliable operation. Additionally, we offer a "one-touch repair valve" that allows for light operation. 【Features】 ■ Large volume air intake and exhaust in a short time ■ Reliable operation ■ Rapid exhaust ■ Compact ■ Lightweight *For more details, please refer to the PDF materials or feel free to contact us.

• Piping Materials

This product is a pressure reducing valve for water supply, industrial water, and agricultural water. Thanks to the action of the needle built into the main valve, there is no sudden closure operation. Additionally, even if the flow rate on the downstream side drops to zero, there will be no equal pressure, and no other power source is required. We offer a wide range of products, including level control valves and pressure reducing valves, starting with the "A-14 type." 【Features】 ■ No sudden closure operation ■ No equal pressure even if the downstream flow rate is zero ■ No other power source required ■ Simple structure with no risk of failure ■ Automatic cleaning prevents clogging of the needle section *For more details, please refer to the catalog or feel free to contact us.
