Eccentric rotary valves combine the high Cv value of rotary valves with the precise control performance of control valves, making them particularly suitable for applications involving high differential pressure, high flow rates, erosive fluids, or media containing solid particles.
Our control valves are engineered with optimized flow paths and control trims to deliver accurate, repeatable control across a wide operating range.
Specialized designs are available for high pressure, high temperature, corrosive, abrasive, and high differential pressure applications.
We offer a wide selection of valve body and trim materials, carefully selected to match process media and service conditions.operation.
The eccentric rotary valve is a high-performance control valve with an eccentric valve core as its core component. It achieves continuous regulation or shut-off of media flow, pressure, or level through the rotational movement of the valve core around an eccentric axis. This type of valve combines the high Cv value of rotary valves with the precise control performance of control valves, making it particularly suitable for high differential pressure, high flow rate, erosive, or particle-containing media applications.
Core Advantages:
1. Strong erosion and wear resistance
The eccentric structure reduces frontal erosion between the valve core and valve seat, making it suitable for high-velocity media.
2. Excellent control performance
Stable flow characteristics and high control accuracy, suitable for continuous regulation applications.
3. Reliable sealing
Optional metal hard seal or soft and hard composite seal to meet different temperature and pressure ratings.
4. Adaptable to complex media
Suitable for media containing particles, fibers, slurries, and high-viscosity fluids.
6. Low torque and long service life
Low opening and closing resistance, allowing for more flexible actuator selection.
Typical Application Areas:
• Chemical and coal chemical plants
• Power, metallurgy, and energy systems
• Papermaking, pulp, and solid-liquid two-phase media
• Environmental protection, water treatment, and desulfurization and denitrification systems
• Oil, natural gas, and high differential pressure applications
High adjustment accuracy and stable control
Suitable for high temperature, high pressure, and harsh operating conditions
