Solenoid valve in the selection of a Note: Applicability of the fluid in the pipeline must be selected and the solenoid valve series models in the same medium. Fluid temperature must be less than the selected solenoid valve calibration temperature. Solenoid valve to allow liquid viscosity generally below 20CST, greater than 20CST should be noted. Working pressure, the maximum pressure pipe when less than 0.04MPa should be used, such as ZS, 2W, ZQDF, ZCM series, such as direct acting and step-by-step; minimum working pressure greater than 0.04MPa can be used when the pilot Differential) solenoid valve; maximum working pressure difference should be less than the maximum calibration solenoid valve pressure; general solenoid valve are one-way work, so pay attention to whether there is anti-pressure difference, if installed check valve. Low fluid cleanliness should be installed in front of the solenoid valve Hongfeng valve factory filter, the general requirements of the solenoid valve cleanliness is better. Pay attention to the flow aperture and take over the caliber; solenoid valve generally only switch two control; conditions allow please install the bypass pipe, easy maintenance; water hammer phenomenon to be customized solenoid valve opening and closing time adjustment. Note that the ambient temperature on the solenoid valve power supply current and power consumption should be selected according to the output capacity, the power supply voltage is generally allowed to ± 10%, we must pay attention to AC starting VA value higher. Second, the reliability of the solenoid valve is divided into two types of normally closed and normally open; generally use the normally closed type, power open, power off; but a very long time to open a very short time to open the normally open type. Action time is very short When the frequency is higher, select the direct-acting type, large-diameter selection of fast series. Third, the general safety of the solenoid valve is not waterproof, please do not allow the waterproof conditions, the factory can be customized. The highest nominal pressure solenoid valve nominal pressure must exceed the maximum pressure within the pipeline, otherwise the service life will be shortened or other unexpected situations. A corrosive liquid should be used in all stainless steel, corrosive fluids should use the plastic king (SLF) solenoid valve. Explosive environment must choose the appropriate explosion-proof products. Fourth, the economy There are many solenoid valve can be universal, but to meet the above three points should be based on the selection of the most economical products.
SMD2835 Led Strip Light
Rhein Lighting has developed a line of the high voltage 2835 Led Strip Light which is perfect for home, office and outdoor decoration. The light strip has multiple colors such as white, red, blue, yellow, green and RGB etc. The strip light has clear PVC tubing, which is flexible, transparent and durable and it can be shaped, formed or bent in any angle to perfectly fit the space being decorated.
The led rope light has come with different options of lengths in a reel, which has 50ft, 100ft and 150ft. The 120v Led Strip Light can be cut in every 1.64ft/0.5m along the cutting marks, without damaging the rest strips.
The Led strip light is ETL certified, which is Eco-Friendly, No splash and UV, without mercury and no damage to human and environment.
Rhein Lighting is specialized in the design and manufacture of led panel downlight, led slim down light, backlit Led Panel Light, led rope light, led strip light, led plant light and Led Grow Light etc.
