The regulating valve combines a newly designed linear ball valve, a new digital positioner with automatic correction function, and a pneumatic diaphragm actuator. This integrated design greatly reduces the cost of acquisition, installation, operation and maintenance. At the same time, it has superior performance:
It can maintain excellent floating range and repeatability even when reaching the maximum flow rate of conventional ball valves.
Excellent control accuracy
Digital positioner for direct installation without casing
Different cutting and material options to meet almost all application conditions
No need for tools and process experience for maintenance personnel Quick installation and simple setup are possible
Globally available and easily available
This new product not only meets the cost-effectiveness requirements of processing companies, but also ensures consistent high quality.

Features:
Maximum capacity flow can replace most process control products in large flow conventional applications such as petroleum Natural gas, chemicals, electricity, etc. Compared with the same product, the maximum capacity flow rate has increased by %.
Cavitation regulation/noise attenuation is particularly suitable for general applications requiring high noise control and cavitation regulation. These cutting solutions include unbalanced, pressure balanced and multi-flow anti-noise, anti-cavitation.
Smaller, lighter, and more cost-effective: products with the same maximum capacity and flow are smaller, lighter, and more cost-effective.
Large size stopper rod: Virtually eliminates the possibility of shaft failure. Heavy-duty plug stems have a larger surface area to reduce valve guide wear, improving reliability and extending valve life. In case of emergency shutdown, the sturdy stopper rod can withstand the thrust of the actuator and push to the single seat cutting of the valve.
Deeper stuffing box: Supports most packing configurations in addition to the standard - field loaded emission control packing method. Filling includes upper equipment and slide equipment. The latter is used to remove liquid from the stopper rod. The distance between the upper device and the slide device is far enough to prevent contamination of the media.
Double guide: ensures precise plugging and seat alignment. Sparsely arranged, graphite-lined stainless steel conduits enable a wider usable temperature range and avoid conduit/plug rod wear
Plunger-shaped valve core design: applicable to modified equal percentage, linear and fast opening flow characteristics. As well as a variety of cut types, excellent variation, repeatability and clarity.
