SHUANGLIN
The SHUANGLIN VALVE Differential Pressure Bypass Valve is designed to automatically balance pressure differences in closed-loop heating and cooling systems. When the differential pressure exceeds the preset value, the valve opens automatically to bypass excess flow, helping maintain a stable operating pressure throughout the system. This protects circulation pumps, reduces flow noise, and improves the overall efficiency of HVAC installations.
Manufactured from high-quality brass and equipped with an adjustable pressure setting mechanism, this valve provides accurate pressure control and dependable long-term performance. Available in DN20 to DN50, it is suitable for residential, commercial, and industrial hydronic systems where pressure stability is essential.
