Summary of prerequisites:
The most widely defined definition of an actuator for a hydraulic control valve is a drive that provides linear or rotational motion that utilizes a drive energy source and operates under certain control signals. The hydraulic control valve actuator uses liquid, gas, electric or other energy sources and converts it into a drive by a motor, cylinder or other device. The basic actuator is used to drive the hydraulic control valve to a fully open or fully closed position.
Any hydraulic control valve actuator is a device that uses energy to drive a valve. The hydraulic control valve unit may be a manually operated gear set, a hydraulic control valve to open and close the valve, or a smart electronic component with complex control and measurement devices for continuous valve adjustment. With the development of microelectronics technology, hydraulic control valve actuators have become more complicated. The early actuators were simply motor gearing with position sensing switches. Today's actuators already have more advanced features, and the hydraulic control valve not only opens or closes the valve but also detects the valve and actuator operating conditions to provide a variety of data for predictive maintenance.

4.0MM SPC Vinyl Flooring can be easily installed on different type of floor base, either concrete, ceramic or existing flooring;
It`s formaldehyde free, completely safe flooring covering materials for both residential and public environment.
UV coating is a very important and necessary processing for SPC Flooring (Rigid vinyl plank), which is processed after the extrusion or lamination and before profiling (chamfering).
The main reasons for UV coating on SPC flooring (Rigid vinyl plank) are as to enhance the surface wear-resistance feature, we use 0.3mm (12mil) or 0.5mm (20mil) wear-layer on our SPC Vinyl Flooring to make it strong wear-resistance for heavy traffic or home using.
