Features & Benefits
Precise adjustment, large adjustability ratio
The valve core is designed with a V-shaped notch. When partially opened, the V-shaped port and the valve seat form a fan-shaped throttling area. It has an inherent flow rate characteristic of approximately equal percentages and an adjustable ratio of up to 200:1. It can provide precise flow control over a wide range and ensure control accuracy even in low flow rates or high viscosity media.
Super shearing and self-cleaning capabilities
The valve core and the valve seat rotate without clearance. During the closing process, the V-shaped notch and the valve seat generate a wedge-shaped shear force, which can effectively cut off impurities such as fibers, scale, and slurry, and at the same time scrape off deposits adhering to the sealing surface to achieve self-cleaning function, effectively prevent the valve from jamming and blocking, and is especially suitable for the working conditions of pipeline scale freezing or containing fiber particles.
Large circulation capacity and low flow resistance
With its streamlined shape and full right-angle rotation control, the flow cross-section is similar to that of a pipeline when fully open, resulting in particularly large flow capacity, low flow resistance, and minimal pressure loss. Therefore, a valve with a smaller diameter can be selected, which is more economical and practical.
Excellent sealing performance and long service life
It adopts an elastic movable metal valve seat with a self-service compensation function, and can automatically compensate for the wear of the sealing surface during long-term use. Metal hard seals meet ANSI Class V standards, offering excellent sealing performance and ultra-long service life.
Compact structure and high sensitivity
The valve body has a unified structure, is sturdy and durable, is not affected by pipeline pressure, and can avoid valve body leakage. It adopts a double bearing structure, which has high mechanical stability and low activate torque, ensuring excellent sensitivity and sensing speed of the valve. The structure is compact and small, and the installation and maintenance are convenient.
