The development of two different characteristics of the control valve film adjustment valve
It is reported that the introduction of the new generation of rotary valve, RPV6, by the company has made this highly functional control valve stand out in the control valve industry. Not only does it combine the advantages of various types of valves, but it has also been widely praised by users for reducing weight and height by up to 30%. Now, let's take a closer look at what makes the RPV6 unique.
The RPV6 is a high-performance pneumatic control valve developed using advanced German technology, representing one of the most advanced products on the international market. Compared to traditional pneumatic film regulators, the biggest difference lies in its design and performance.
Firstly, the RPV6 uses a double-acting cylinder actuator with a spring, providing strong thrust, high rigidity, and fast response. It features a piston that receives pure compressed air from both the top and bottom, with the surface treated through hard anodizing to increase hardness and prevent fading or corrosion. This model can handle gas pressures up to 1.0 MPa and can switch and close even under high differential pressure conditions. In case of a spring failure, the valve can automatically open or close, ensuring system safety. The cylinder is made from die-cast aluminum alloy, making it stronger, more compact, lighter, and easier to handle compared to film actuators. It also comes with a dual-acting positioner for more precise control and improved stability.
Secondly, the RPV6 features a modular design, making assembly and on-site maintenance extremely convenient. Unlike traditional control valves that use threaded valve seats, which are complex and difficult to maintain, the RPV6 uses a non-threaded connection. The valve seat is fixed by the pressure applied by the bonnet and cage, allowing for self-assembly during installation, ensuring concentricity and minimizing leakage without the need for grinding. Replacement of parts is simple and accurate.
Additionally, the seat retainer cage guides the fluid, buffers pressure, protects the valve body from erosion, cavitation, and noise, while also facilitating easy maintenance and significantly extending the service life of the valve.
In summary, the RPV6 represents the latest generation of pneumatic control valves, combining advanced technology, superior performance, high quality, low weight, and ease of maintenance. It combines the benefits of single-seat and cage valves, and by simply replacing the spool and seat, it can achieve regulation, shut-off, pressure relief, and leak prevention. It is a cutting-edge solution for modern control systems.
