Product introduction:
L202305 cage type single seat regulating valve, using top guided imbalance type structure, high strength, heavy load, S-streamlined channel, small pressure drop loss, large flow coefficient, wide adjustable range, and high accuracy of flow characteristics. This regulating valve is suitable for heavy loads, normal or harsh working conditions, and can be closed tightly and suitable for controlling fluids or gases under various pressures and temperatures control, adapt to various actuators, and play a regulatory role.
The valve cage is used to compress the valve seat design, reducing lateral load and valve core vibration, reduced friction and extended the service life of the control valve. Flow open design, the flow direction of the medium tends towards the direction of the control valve opening, with a small flow rate state, good controllability. Special measures for noise reduction and cavitation resistance valve cage types can be selected according to the working conditions

Product features:
1. Multiple operational way to choose, the electric, pneumatic, electrichydrualic actuators can be choosen which can be easily connected and controlled with industrial automation systems, achieving remote control and real-time monitoring of the valve.
2. Valve trim characteristics: valve seat guided unbalanced trim quick release structure, cage pressure valve seat (for stainless steel valve body). Valve seat in deep cold environment (aluminum alloy valve body)
3. External extraction type upper valve cover internal parts (optional for DN100 caliber and below)
4. High performance regulation: Due to the use of a combined three-way design, the electric combined three-way regulating valve has high flow regulation performance. When the fluid flows through the valve, the regulating performance of the valve is stable and not easily affected by factors such as fluid properties and temperature.
