Solenoid valve factory after-sales service heart analyses the four performance of solenoid valve for you

Solenoid valve factory after-sales service heart as you analyze the four performance of solenoid valve solenoid valve four performance after-sales service department of solenoid valve security king of corrosive medium appropriate chooses plastic electromagnetic valve and all stainless steel; Strong corrosive medium must choose the isolation diaphragm. Cases of CDF. ZCF。 Neutral medium, appropriate chooses steel alloy for valve shell material of solenoid valve, otherwise, has a tendency to rust particles fall off valve shell, especially the actions do not frequent occasions. Ammonia valve can't adopt a copper. Explosive environment must choose corresponding level of explosion-proof products, open-air installation or dust should choose more occasions waterproof, dust-proof varieties. Nominal pressure solenoid should exceed the maximum working pressure inside. The applicability of the solenoid valve medium, nature gas, liquid or mixed state respectively choose different kinds of electromagnetic valve, example ZQDF for air ZQDF - Y used for liquid, ZQDF - ( Or) Used for steam, otherwise easy cause misoperation. ZDF series multi-function solenoid valve can be all in the air. The liquid. When the best order confess medium condition, installation mode again users don't have to. Medium temperature of different specifications products, otherwise the coil will burn, seal aging, seriously affect the life of life. Medium viscosity, usually under cSt. If more than this value, size is greater than the mm with ZDF series multi-function solenoid valve for special orders. Size is smaller than the mm high viscosity solenoid valve. When medium cleanness is not high in front of the solenoid valve should be equipped with recoil filter valve, low pressure straight moving diaphragm electromagnetic valve is used in the fair as such as a CD - P。 If the directional flow, and are not allowed to go back ZDF - N and ZQDF - N list must be two-way flow, for special requirements, please put forward. Medium temperature should fall in the range of electromagnetic valve allows. Pipe parameters to the flow direction of medium according to the requirements and selection of pipe connection valve his and models. For example, to a pipeline to the two pipes switching, smaller size of CA and the government, medium, or large please choose ZDF - Z/。 And as control two pipe flow, please choose ZDF - Z/etc. Kv value is selected according to the flow and valve nominal diameter, also optional with pipe diameter. Please note that some manufacturer not marked Kv value, often valve hole diameter smaller than interface, must not covet the broth and relatively low prices. Working pressure difference minimum differential pressure above, Mpa is can choose indirect guiding type; The minimum working pressure difference of close to or less than zero must choose direct acting or step by step. Environmental conditions of maximum and minimum temperature should fall within the scope of the permit, such as ultra difference should be made for special orders. Environment relative humidity is high and there is water drench, etc, should choose waterproof solenoid valve. Often is vibration in environment, occasions, such as turbulence and shock should choose special varieties, such as Marine electromagnetic valve. Used in corrosive or explosive environment should be prioritized according to security requirements resistant to corrosion. If environment space limited, please choose multi-function solenoid valve, because of its saves bypass and third hand dynamic valve and facilitate online servicing. According to the types of power supply, power supply condition choose ac and dc electromagnetic valve, respectively. In general the ac power access convenient. Voltage specifications with priority choose ACV, DCV listed as far as possible. Power supply voltage fluctuation usually communicate choose + % %, %, dc + % to the left or right, if poor, should be regulated measures or request a special order. Ordinary electromagnetic valve, only two places, in the high control accuracy requirement and parameters for smooth, please choose a number of solenoid valve; ZCF three normally open solenoid valve, with a tiny qi, fully open and closed three flow; 二台, Z/combo multi-function solenoid valve is fully open, open, small open, open, four kinds of traffic. Action time refers to electrical signal through or cut off time of completion of the main valve action, only the company patent product multi-function solenoid valve for opening and closing time adjustment, not only can meet the requirement of control accuracy, and also can prevent the water hammer damage. Leakage samples on the leakage of numerical for commonly used economic level, if too high, please make a special order. The reliability of the electromagnetic valve working life, this is not included in the test project, belongs to the type testing project. In order to ensure the quality of persons to be normal manufacturer of famous brand products. Working standard points duty for a long time, short work and short work over and over again. The company's products are routine for the long term, namely the coil allow electricity work for a long time. Only short time off for a long time the valve opens, the appropriate chooses normally open solenoid valve. In short work and batch is large, can make special order to reduce power consumption. Working frequency action for high frequency structure should be optimized direct acting solenoid valve, power supply to optimizing communication.  action reliability is strictly for the test is not yet officially listed in the electromagnetic valve professional standards in our country, in order to ensure the quality of persons to be normal manufacturer of famous brand products. Some occasions number is not much, but the reliability requirement is high, such as fire fighting, emergency protection, etc. , must not treat STH lightly. A laparoscope, usually connected to a particularly important, also should adopt two double insurance. Electromagnetic valve of the economy is not economy for capital, energy and waste of life choose one of the scale of it, but it must be in safe, applicable and reliable based on the economy, the economy is not only the product price, more to give priority to the function and quality as well as the installation and maintenance, and other accessories need cost, and, more importantly, a solenoid valve in the whole control system in the whole control system and the production line of cost is very low, if covet petty gain and incorrect early damage group is huge. All in all, economy not only refers to the product price, but the performance of the product price is comprehensive cost price.
