Can I say that all the problems associated with traditional straight-through single-seat valves can be solved using slide valve technology? I don’t think it’s necessary, but you can still use the following performance characteristics to relate them to the issues on site and analyze those issues: First, reduced energy consumption. Compared to straight-through valves of the same diameter, slide valve systems experience less unbalanced force; therefore, to overcome the same fluid pressure difference, a actuator with lower output force is sufficient. This reduces the consumption of air and power required for the control valves, and widespread use can significantly cut down on users’ operating costs. II. Light structure and easy installation: The wafer-type valve body is small in size and light in weight, which reduces the overall weight and the space required for installation, thereby enabling the instrumentation of control valves (see the weight comparison chart on the next page). It is easy to install and maintain, can be installed in 360 degrees, and can significantly reduce the space required for factory equipment. III. Stable control and low wear: As the fluid flows through multiple throttling channels, its flow pattern remains relatively stable, reducing turbulence. This lowers the noise generated as the fluid passes through the valve body, and it also reduces the wear and damage to the valve’s internal components, thereby extending the valve’s service life. High-speed fluid jets overlap after passing through the sliding plate of the orifice throttling structure, causing the kinetic energy of the medium to be converted into thermal energy due to mutual collisions and friction, thereby effectively preventing a sudden drop in pressure and reducing bubble formation. On the other hand, this structure causes the bubbles to burst at the center of the pipeline downstream of the valve body, preventing direct damage to the pipeline. Numerous experimental results and user experience show that cavitation and flashing occur at the center of the pipeline 1–2 meters downstream of the slide valve outlet, providing more effective protection for the valve body and the downstream piping. IV. Short stroke and fast response time: Due to the low unbalanced force of the slide-type control valve, its short stroke, and the small volume of the actuator, it is able to respond quickly to control signals, completing the adjustment process in an extremely short time – the total stroke time is less than 2.8 seconds (only 0.2 seconds for switching). V. Tight closure: The slide-type control valve features a metal-to-metal hard-seal design. The slider components achieve overlapping sealing under the action of a pressure difference in the medium; the greater the pressure difference, the better the sealing performance, with leakage levels below ANSI CLASS IV standards. During operation, the sealing surfaces of the sliders grind against each other, and the longer the service life, the better the sealing performance. VI. Self-cleaning function: The shear force generated by the movement of the slider (similar to that of a ball valve) effectively prevents the accumulation of medium, cleans the flow channels, and reduces the risk of blockages. It effectively solves the common problems of valve blockage caused by fine particles, fibrous media, and viscous media. 7. Excellent adjustability: The sliding plate valve is subject to low unbalanced forces, and its actual adjustability can exceed 30:1. It can operate stably over a long period even at low opening degrees; in most operating conditions, one sliding plate control valve can replace two single-seat valves with step control. VIII. Multiple flow capacities: The value of the flow coefficient Cv can be changed simply by replacing the slider assembly. Each diameter has at least 3 available Cv values, and up to 15 available Cv values. If there is a discrepancy between the Cv value required by the actual operating conditions on site and that specified in the product selection, it’s no problem – simply replace the slider assembly. Adjustment is possible simply by replacing the slider assembly: flow characteristics (linear, equal percentage), flow coefficient (Cv value), and safety functions (normally open/normally closed, fail-open/fail-closed)
