YNV HSV-3S 20A Safety Relief Valve – High Lift Pressure Protection Valve

✅ The YNV HSV-3S Size 20A is a high-performance Safety Relief Valve designed to protect pressurized systems from excessive pressure. The valve automatically opens when system pressure exceeds the preset value and closes once pressure returns to a safe operating level, helping safeguard pipelines, pressure vessels, boilers, and industrial equipment.

✅ The HSV-3S belongs to YNV's High Lift Safety Relief Valve series, providing rapid pressure relief with high discharge capacity. Its high-lift design ensures fast valve response during overpressure conditions, improving operational safety and reducing the risk of equipment damage.

✅ The valve body is manufactured from stainless steel, while the bonnet is made of cast bronze for excellent corrosion resistance, mechanical strength, and long service life. The stainless steel disc and seat provide reliable sealing performance and minimize leakage during operation.

✅ Equipped with standard PT threaded connections, the valve is easy to install and replace in existing piping systems. Various spring pressure settings are available to suit different industrial operating requirements and pressure protection applications.

✅ Designed for reliable and continuous service, the HSV-3S is widely used in steam systems, compressed air networks, water pipelines, oil systems, pressure vessels, heating equipment, and industrial process applications where dependable overpressure protection is required.

✅ Manufactured by YNV, a leading South Korean valve manufacturer, the HSV-3S combines high-quality materials, precision engineering, and dependable performance for demanding industrial environments.
