Advantages and features of Vickers throttling check valve
‌Combined with the functions of the check valve and the throttle valve, the throttle plug is used to achieve controlled flow regulation while limiting reverse flow, simplifying the system structure and reducing the number of components.

The conical valve core is quenched and ground, with excellent sealing performance and leakage ≤1%.

‌Precise flow control and adaptability‌

The right-angle check valve design supports large flow (pressure drop ≤0.2 bar), and the straight-through design is suitable for working conditions with small impact and stable throttling.

The limited flow in the normally closed position can be adjusted through the built-in throttle, which is suitable for hydraulic cylinder oil discharge, oil replenishment and other scenarios.

‌Reliability and durability‌

The fully enclosed solenoid coil (IP67 protection) and corrosion-resistant valve body material are suitable for a wide temperature range of -40℃~120℃ and a highly polluted environment.

The modular plug-in design supports quick maintenance and is easy to replace seals or valve cores.

‌Flexible control mode‌

‌Internal control mode‌ automatically adjusts the system pressure, with high stability, suitable for hazardous environments or high-precision demand scenarios.

‌External control mode‌ supports manual or electric quick operation, suitable for systems that need to adjust the flow frequently.

Precautions for use

‌Installation specification‌

Must be installed vertically and the arrow direction is consistent with the fluid flow direction. Reverse installation will cause functional failure or seal damage.

In the hydraulic cylinder oil discharge circuit, the hydraulic control check valve must be installed close to the actuator to avoid pipeline pressure fluctuations affecting the throttling effect.

‌Oil and pollution management‌

The oil cleanliness must reach ISO 16/13 or above, and a filter should be installed at the inlet and cleaned every 2-3 months to prevent impurities from clogging the throttle or valve core.

It is prohibited to use corrosive or high-viscosity media. The maintenance cycle needs to be shortened to every 3 months under high temperature conditions (＞80℃).

‌Pressure and flow limit‌

The control pressure must be ≥20% of the system rated pressure to avoid reverse flow loss of control or abnormal wear of the valve core due to pressure loss.

When used in parallel, ensure that the diameters are consistent to prevent uneven flow distribution or throttling function failure.

‌Maintenance and Fault Prevention‌

When not in use for a long time, the solenoid needs to be activated every 3 months to prevent the valve core from getting stuck or the seal from sticking.

Regularly check the wear of the valve core and the valve seat. It is recommended to replace the seal every 6 months in high temperature or frequent start-stop environments.

Summary
The Vickers throttling check valve has the core advantages of composite function integration, precise flow regulation and wide environmental adaptability. It is suitable for hydraulic cylinder locking, large flow oil discharge and oil replenishment systems. When using, strictly follow the installation direction, oil cleanliness and pressure control specifications to ensure long-term stable operation.
