The back pressure valve prevents siphoning and allows for pressure adjustment! It uses a highly chemical-resistant PTFE diaphragm! There is a lineup of various materials and sizes available!
This is a back pressure valve made of various materials including PTFE, PVDF, PP, CPVC, PVC, Halar, stainless steel, Hastelloy C, and Alloy 20. It has the function to prevent siphoning phenomena! It can be used in lines that require chemical resistance or high-temperature lines. Additionally, by controlling the pressure, it stabilizes pulsation phenomena and the amount of fluid injected, leading to improvements in the quality of the system or unit. Due to its simple structure, parts can be replaced and pressure adjustments can be made without removing it from the line!

Company information
Sunny Trading has consistently specialized in the import and sales of automatic control and labor-saving equipment since its establishment in 1961, actively introducing the latest high-performance machinery and equipment from Europe and the United States to the domestic market. The components for production machinery that we handle are widely adopted in industries such as machinery, electrical, and chemical, and we take pride in our extensive delivery track record to national government agencies, universities, research institutions, and the aerospace industry. The delivered parts are incorporated into machines to complete large production facilities, but confirming the compatibility of the products is essential for this process. We always strive to provide appropriate products by investing technical know-how and time for specification confirmation between overseas manufacturers and our customers. Additionally, we take responsibility for follow-up services, including on-site inspections of delivered products and maintenance. Unlike general trading companies that simply import and sell goods, we pride ourselves on being a trading company with engineering capabilities. Products are commercialized as machines by manufacturers, and they are actively utilized in core industries such as semiconductors, steel, shipbuilding, aerospace, packaging, logistics, and chemicals.
