ភាសាខ្មែរThreaded Stainless-Steel Gate Valves are widely used in water, steam, gas, and light chemical piping systems, where full open/close operation is required to completely stop the flow. In practice, in both residential and industrial projects, selecting the right type of valve directly affects operational efficiency, durability, and maintenance costs.
Made from highly corrosion-resistant 304 or 316 stainless steel with a compact threaded connection, threaded stainless-steel gate valves not only provide excellent sealing performance but also allow easy installation in tight spaces without the need for complex supporting equipment. They are an ideal choice for medium and small systems, especially in environments requiring high hygiene standards or frequent contact with water, oil, gas, or light chemicals.
To give a clearer picture, let’s explore the Wonil threaded stainless-steel gate valve, a valve series that has been trusted and widely chosen by many customers.
Features and Technical Specifications of Wonil Threaded Stainless-Steel Gate Valves
The Wonil threaded stainless-steel gate valve is one of the main product lines of Wonil, a brand with a long-standing reputation in the industrial valve industry. The threaded connection method is commonly used for small-diameter pipes ranging from DN15 to DN50. For larger pipelines, the flanged model of Wonil stainless-steel gate valves can be used.
The Wonil gate valve is compact, with a CF8 stainless-steel body and a polished surface. Key parameters such as pressure rating, size, and material are cast on the valve body. The valve features a round metal handwheel painted red. Both ends are threaded, allowing a secure connection to the pipeline.
