Product introduction
The single-side union valve is a practical pipeline valve, unique in that one end is equipped with a union joint. A union is a detachable connector that allows the valve to be installed or repaired without disassembling the entire pipeline. Simply loosen the union to separate the valve body from the pipeline, significantly reducing maintenance time and cost. This valve is typically made of corrosion-resistant materials such as brass, stainless steel, or cast iron to ensure durability under various working conditions. The valve disc is designed with flat or conical sealing surfaces, combined with PTFE or rubber gaskets, to achieve good sealing effect and prevent leakage. The operation method is mostly handwheel rotation to drive the valve stem up and down, controlling the opening or closing of the valve disc. The single-side union valve is suitable for non-corrosive media such as water, oil, and gas, with working pressure typically 1.0-2.5MPa and operating temperature range of -20°C to 150°C. Its simple structure, low flow resistance, and easy cleaning and replacement of the valve core make it especially suitable for pipeline systems that require frequent maintenance. It is widely used in HVAC, fire protection systems, industrial circulating water, and agricultural irrigation. When selecting, pay attention to interface size, material, and media compatibility.
