HONEYWELL VBF3K21S0D 3-Way Actuated Control Ball Valve

Product Description

The HONEYWELL VBF3K21S0D is a 3-way actuated control ball valve designed for effective control of hot and chilled water with glycol solutions up to fifty percent in closed-loop HVAC systems. This valve features a flanged cast iron body, ensuring durability and reliability in various applications. The Teflon seat enhances performance and reduces wear, while the 316 stainless steel stem provides additional resistance to corrosion. The valve is capable of both two-position or modulating functions, allowing for flexible use. It supports non-isolating mixing or diverting control, ideal for temperature regulation in HVAC setups. A removable manual operating handle is included for valve control during installation or power outages. The valve can also be configured in the field for normally open or normally closed fail-safe positions.
