BELIMO BU6200L+SY3-230-3-T

BU6200L+SY3‑230‑3‑T solves a common challenge in large‑scale HVAC, water distribution or chilled/hot water systems: how to precisely control high flow volumes while ensuring reliable shut-off under pressure. The BU6200L butterfly valve — sized DN200 — is built for heavy-duty service, with a ductile cast‑iron body, stainless-steel disc, and EPDM seat that together deliver a leak‑tight seal and long life. When combined with the SY3‑230‑3‑T actuator, you get an electric, quarter‑turn valve assembly capable of robust on/off control. The 150 Nm torque of the actuator ensures the valve closes firmly even under challenging pressure or flow conditions, while its AC 230 V supply is compatible with standard building electrical systems.

The actuator is housed in a weather‑proof, IP67-rated aluminum enclosure — protecting it from dust, moisture and harsh environments, making the unit suitable for outdoor or industrial installations. Built-in manual override lets technicians operate the valve manually during maintenance or power outages. Compared to manual valves or low‑torque actuated solutions, this combo offers stronger sealing, better control under load, less maintenance and longer lifespan — ideal for large buildings, industrial plants, or infrastructure where downtime or leaks are costly.
