OverviewThe LT942X Flow and Pressure Regulating Valve is a multifunctional hydraulic control valve featuring a piston-based design. Drawing on advanced domestic and international technologies, it achieves precise linear regulation of flow rate, pressure, and liquid level by adjusting the annular flow channel area through the piston's axial linear motion within the valve chamber. This versatile valve performs exceptionally well not only with clean water but also with natural river/lake water and mildly polluted water. Widely used in water treatment plants, power plants, water diversion projects, and municipal water supply systems requiring complex flow and pressure control, it delivers reliable performance across diverse applications.

Its core piston mechanism and specialized material selection fundamentally resolve the common issues of scaling and jamming in conventional control valves. The flow channel design effectively disperses water flow to prevent impurity blockage.2. Efficient energy dissipation and cavitation resistance: The valve employs multi-hole jet collision or composite hole counteraction principles to dissipate energy, effectively reducing cavitation under high pressure differentials while minimizing valve noise and pipeline vibrations.3. Sealed tightly with integrated functions: Featuring dual sealing of metal and rubber, it achieves bubble-level sealing and zero-leak closure, functioning as a reliable shut-off valve without additional installation. This single valve combines multiple functions including flow regulation, pressure reduction/stabilization, and pressure relief/holding.4. Intelligent control with precision adjustment: Equipped with integrated electronic circuits or internationally recognized brand actuators, it accepts 4-20mA standard signals for high-precision automatic regulation and remote control. Customizable drive modes include manual, electric, or hydraulic systems as required.5. Long-lasting and flexible installation: Key components are made of wear-resistant materials like stainless steel, ensuring a long service life. The valve supports both horizontal (side-mounted) and vertical (top-mounted) installation, accommodating various pipeline layouts.

The TD342X electric turbine throttling butterfly valve is a flange butterfly valve featuring a turbine worm drive mechanism and dual eccentric design. By precisely rotating the butterfly plate within a 0° to 90° range, it enables continuous flow regulation and reliable shut-off of pipeline media. Balancing operational flexibility with airtight sealing, this valve is widely used in water treatment plants, power plants, municipal water supply systems, chemical facilities, and industrial circulating water systems requiring precise flow control.TD342X Electric Turbine Throttling Butterfly Valve Product DiagramFeature1. The system features precise regulation and effortless operation. Its turbine worm gear mechanism delivers a high transmission ratio and substantial torque output, enabling effortless flow control under large-diameter or high-pressure-difference conditions. The design also ensures accurate butterfly plate opening control with self-locking functionality.2. Double eccentric design ensures reliable sealing: The dual eccentric configuration (with valve stem axis offset from both butterfly plate center and valve body center) enables the butterfly plate to disengage from the valve seat instantly during opening, significantly reducing friction and extending seal durability. During closing, the progressively tighter sealing effect ensures bidirectional sealing reliability.3. Low flow resistance and energy-efficient: The butterfly plate features a frame-type design with high structural strength. When fully open, it minimizes obstruction to the flow channel, resulting in low flow resistance and reduced energy consumption in pipeline systems.4. Easy installation and maintenance: Compact design with lightweight construction. The valve supports multiple installation orientations (horizontal/vertical) and is not restricted by fluid flow direction. Wear-prone components like sealing rings are replaceable, eliminating the need to disassemble the valve body during maintenance and simplifying the process.5. Versatile material options and adaptable performance: Key components like valve bodies and butterfly plates can be manufactured from cast iron, cast steel, or stainless steel, tailored to specific operational requirements. The sealing assembly typically combines stainless steel with nitrile rubber, ensuring compatibility with water, air, oil-based fluids, and mildly corrosive media.

The LT342X piston type flow and pressure regulating valve is a high-performance multifunctional control valve designed based on fluid mechanics principles, incorporating advanced technologies from both domestic and international sources. Featuring a unique piston structure that adjusts flow channel area through axial movement, it enables precise and continuous regulation of pipeline medium flow and pressure. Not only is it suitable for clean water, but also demonstrates excellent tolerance for natural river and lake water as well as mild wastewater. This effectively addresses the common issues of scaling and clogging in traditional valves, making it widely adopted in critical pipeline systems such as power plants, water diversion projects, and urban-rural water supply networks.

High-pressure energy dissipation and cavitation resistance: The valve body features a streamlined, axisymmetric flow channel design that significantly reduces noise and vibration. Its unique piston-and-cage (fan ring) structure effectively dissipates energy through multi-hole jet collisions, ensuring cavitation prevention even under inlet/outlet pressure differentials up to 40 kg/cm², thus safeguarding pipeline systems.2. Reliable sealing with zero-leakage closure: Featuring a metal-to-metal primary seal and floating valve seat design, it delivers exceptional sealing performance. When fully closed, the valve ensures complete leakage-free operation, making it a reliable shut-off valve.3. High resistance and durability with extended service life: The specially designed flow path and robust piston structure enable it to handle fluids containing small particles like sand. Critical components such as valve seats and guide rails are made of special stainless steel, with a hardness three times that of ordinary stainless steel, offering excellent wear and corrosion resistance. The designed service life reaches up to 30 years.4. The intelligent valve features excellent linear regulation characteristics across the full flow range, ensuring stable and precise control. It can be equipped with electric drive devices, PLC control systems, and sensors to achieve both local and remote intelligent automation, with user-friendly operation.5. The operating force is small and the flow resistance is low. The motion direction of the operating part (piston) is consistent with the direction of the fluid, and the operating torque is small. The optimized flow channel makes the pressure loss of the valve small, which helps to reduce the power consumption of the pipe network.
