The lining fluorine shut-off valve produced by Hebei Huayu Valve is a forced-sealed valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface to not leak. The 800w grow light has many features that make it an ideal choice for indoor planting. With Samsung leds and high efficiency driver and frame, our grow lamp 800 watt, best full spectrum Led Grow Light has an ultra-strong luminous intensity and high energy efficiency, providing high-quality illumination that helps photosynthesis and promote healthy growth of plants. It also features a unique design that can be folded for easier portability and energy-saving. With a coverage area of up to 6X6FT, 800W Grow Light is a great plant light for indoor plants.

The lining fluorine shut-off valve produced by Hebei Huayu Valve is a forced-sealed valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface to not leak. When the medium enters the valve six from below the valve flap, the resistance to be overcome by the operating force is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The force of closing the valve is greater than the force of opening the valve, so the valve The diameter of the rod is large, otherwise the valve stem will be bent. In recent years, since the soft seal gate valve appears, the medium flow direction of the shut-off valve is changed from the valve flap to the valve chamber. At this time, under the action of the medium pressure, the force to close the valve is small, and the force of opening the valve is large, and the diameter of the valve stem Can be reduced accordingly. At the same time, this type of valve is also tight under the action of the medium. China's valve "three-way to give" has stipulated that the flow of the stop valve, all from top to bottom. When the lining fluorine shut-off valve is opened, the opening height of the valve flap is 25% to 30% of the nominal diameter, and the flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the full open position of the shutoff valve should be determined by the stroke of the valve flap.
