Nu West Leda Fcv 150 -
The valve combines two distinct fluid streams entering through two separate inlet ports into a single, uniform outlet stream. This is commonly used to control process temperatures by blending hot and cold liquids.
The "FCV" designation highlights its use as a dedicated flow control mechanism. Armed with an electro-pneumatic (E/P) positioner, the valve interprets a variable electronic signal (typically 4–20mA) from a centralized control loop. It translates this message into a precise mechanical pneumatic response, allowing micro-adjustments to the valve stem position. 3. Streamlined Fluid Dynamics

Unlike static bottom drains that can become clogged with waste feed and feces, the Leda FCV 150 utilizes a patented floating mechanism. This allows the unit to maintain a precise water level seal, effectively separating solid waste from the water column while preventing feed loss. The valve combines two distinct fluid streams entering
