Cage double-seat control valve
Cage double seat control valve adopts the cage guided structure and pressure balanced plug. this kind of control valve adopts the cage double-seat structure and is mainly used in applications that do not have high requirements for shut-off class. As it adopts the double-seat structure, and the two sealing faces are metal seals, the temperature range is wider. The plug makes use of the pressure balanced structure, the opening and closing force is low and the media under service conditions with high differential pressure can be controlled through relatively low actuator thrust. It is widely used for fluid control on pipelines of middle and low temperatures and middle and low pressures that require good dynamic stability. With such features as good sealing performance, high allowable differential pressure, cage guiding, large guiding area, good stability and compact structure, it can realize fast replacement of trims on the line with high maintenance efficiency, saving manpower and time. The balanced plug structure makes sure that the actuator thrust required is the lowest.
The Cage Double Seat Control Valve is an advanced flow control solution designed for a wide range of industrial applications. This valve features a double-seat design that ensures excellent shut-off capabilities, significantly minimizing the risk of leakage and enhancing operational efficiency. The cage-style design offers superior stability and precise control over fluid flow, making it ideal for managing both high and low-pressure systems. Constructed from durable materials, this valve can withstand harsh operating conditions and offers extended service life. The valve’s design incorporates a balanced plug, which reduces the actuator force needed to move the plug, providing more accurate control. Furthermore, the Cage Double-Seat Control Valve is available in various sizes and material options, allowing for customization based on specific process requirements. Its straightforward installation and maintenance procedures make it a practical and efficient choice for any process system. Whether you’re dealing with steam, gas, or liquid flows, the Cage Double-Seat Control Valve provides reliable and secure flow control, ensuring your operations run smoothly and safely.
