USV

LENO系列静态平衡阀 USV-M 及USV-I 套装

USV valves are designed for manual hydronic balancing of heating and cooling systems. USV-I (red knob) is used together with USV-M to limit the flow in heating or cooling installation or can work separately as manual balancing valves for flow limitation. If certain pipe sectors do not require a control of differental pressure, USV-I and USV-M can be used as shut-off- and measuring valve. USV-M (blue knob) valve can be upgraded into an automatic USV-PV balancing valve. USV-M is designed for installation in the return pipe. Upgrading from manual to automatic balancing is done by mounting PV-controller to an USV-M valve.

USV-I / USV-M

USV 阀门专为供暖和制冷系统的手动水力平衡而设计。

USV-I（红色旋钮）可与 USV-M 配合使用，用于限制供暖或制冷系统中的流量，也可单独用作手动平衡阀。如果某些管道段不需要控制压差，USV-I 和 USV-M 可用作截止阀和测量阀。

USV-M（蓝色旋钮）阀门可升级为自动 USV-PV 平衡阀。USV-M 设计用于安装在回水管中。

通过将 PV 控制器安装到 USV-M 阀门上，即可从手动平衡升级到自动平衡。

升级过程中系统无需减压，kV 值也不会改变。 USV-PV 可保持立管两端的恒定压差。

由于其特殊设计，USV-PV 的隔膜外壳和阀锥之间连接牢固。

USV-S

USV-S valves are designed for manual hydronic balancing of heating and cooling systems.

USV-S (black knob) is used to limit the flow in heating or cooling installation or can work separately as manual balancing valves for flow limitation.

USV-S is compact valves in which the operating elements and connections are placed within an arc of 90°, so that in spite of small valve dimensions, access for installation and operation is optimal.
