Description
The 3FSA.
S valve family is designed for precise mixing and diverting control in heating, cooling and industrial HVAC systems where enhanced stem sealing is required. With a robust globe valve design and bellows-sealed stem construction, these valves ensure stable regulation, reliable operation and long-term tightness in demanding installations.
The three-way configuration enables accurate mixing or diverting of flow, while the stainless steel bellows provides an additional level of protection against leakage, making the 3FSA.
S series suitable for systems operating under elevated temperature conditions.
