We offer the 'DS404 Type Water Hammer Prevention Check Valve' made of rigid polyvinyl chloride (PVC) or rigid polyvinyl chloride (PVC) + FRP. It features a vertical lift type disc valve structure that is held down by a spring. The valve opens slowly when the pump starts and closes faster than the liquid falls when the pump stops, thereby reducing the impact of water hammer. 【Specifications: Connection and Size】 ■ PVC - Flanged: 40 to 100A ■ PVC + FRP - Flanged: 40 to 250A *For more details, please download the PDF or feel free to contact us.

Our company offers the 'Model 707 Breather Valve', which is suitable for chemical tanks made of FRP or polyethylene, as well as stainless steel storage tanks, due to its lightweight and rust-free properties. During the injection and discharge of liquids into the tank, as well as due to the expansion and contraction of air or gas caused by temperature changes, the valve automatically regulates the pressure inside the tank to maintain it at normal levels and prevent damage. It is particularly used for chemical tanks containing hydrochloric acid, sulfuric acid, nitric acid, sodium hypochlorite, caustic soda, PAC, sulfuric acid bands, and ferrous chloride, among others. 【Specifications】 ■ Connection & Size - PVC/PP Flanged type: 25 to 100A ■ Operating Pressure - Please specify within the range of +30 to +300 mmAq and -30 to -100 mmAq *For safety, it will be set to operate earlier than the specified pressure. *For more details, please download the PDF or feel free to contact us.

The "902 Type Diaphragm Back Pressure Valve" is a diaphragm direct-acting structure primarily used for liquids such as water and various chemicals, ensuring reliable operation as a back pressure valve. The spring-operated part is completely separated from the liquid contact area by the diaphragm. Since no metal is used in the liquid contact area, there is no concern about corrosion from aggressive chemicals. Additionally, it can be installed in either a vertical or horizontal position. 【Functions】 ■ As a safety valve ■ As a relief valve ■ As a fall prevention valve ■ As a siphon prevention valve ■ As a differential pressure discharge and backflow prevention valve *For more details, please download the PDF or feel free to contact us.

The "MMN1600 Type Needle Valve Air Valve (Intake and Exhaust)" is an air valve developed specifically for sodium hypochlorite. Sodium hypochlorite decomposes, leaving behind particles of salt (sodium chloride) crystals, which tend to adhere to the valve seat, negatively affecting the sealing performance of the valve seat and potentially causing leaks. To improve sealing performance, a needle valve has been added to the float ball. This valve is suitable not only for sodium hypochlorite but also for liquids that tend to form crystal particles or contain foreign substances. 【Specifications】 ■ Connection and Size - PVC Flanged type: 15 to 25A (Standard is flanges of the same size on both ends; custom orders for flanges of different sizes can be accommodated) ■ Others - The needle is standard in titanium, and PVC is available upon special request. *For more details, please download the PDF or feel free to contact us.

Our company offers the "Model 882 Bucket Type Strainer (Straight Type)" which is designed with a very large filtration area, making it suitable for fluid filtration and requiring fewer cleaning cycles compared to Y-type strainers. The main body is a cylindrical container with good shape balance, and the basket-type filter element is typically extracted upwards, allowing impurities such as captured debris to be removed without spilling, making handling during cleaning easy. 【Specifications: Connection and Size】 ■ PVC - Flanged: 15 to 150A (Custom sizes 200A and 250A): Punching type filter element only ■ PP - Flanged: 15 to 150A *For more details, please download the PDF or feel free to contact us.

Our company offers the 'MM801 Type Molded Y-Strainer', which is highly resistant to corrosion and chemicals, for use with seawater, various acids, alkalis, and other chemical agents. The element can be easily removed by opening and closing with a cap nut during cleaning or replacement of the filter element. It features a large flow path, a thick and robust body, and sufficient filtration area, making it an excellent choice as a Y-strainer. 【Specifications: Connection & Size】 ■ PVC - Flanged: 15–50A - Threaded: 15–50A - TS type: 15–50A - Flexible union TS type: 15–50A (except for 32A) - Flexible union threaded type: 15–50A (except for 32A) ■ PP - Flanged: 15–50A - Threaded: 15–50A - TS type: 15–50A (except for 32A) *For more details, please download the PDF or feel free to contact us.

The "M401 type" does not use any metal, making it an excellent check valve to be attached to the end of a suction pipe, with outstanding corrosion and chemical resistance. Additionally, the large flow area and smooth flow path result in minimal resistance to the fluid, allowing for sufficient flow rate, low pressure loss, and reduced burden on the pump. We also offer lever-operated foot valves and foot strainers. Please feel free to contact us if you have any requests. *For more details, please download the PDF (specification sheet) or contact us.
