Cage Style Unbalanced Single Seat Globe Control Valve

The Cage Style Unbalanced Single Seat Globe control Valve is designed with a top-guided configuration and is ideal for high-pressure, heavy-duty applications where stringent shutoff requirements are crucial. Its cage design ensures the seat ring is securely retained, reducing side-loading forces and vibrations while minimizing friction and extending the valve's lifecycle.
This control valve is suitable for severe service conditions, where precise control is necessary. Its flow-to-open design directs fluids toward the valve opening, providing excellent control with small flow streams.
