I. Security: Do not pay attention to safety that will have a disaster! 1. Erosive media: The choice of plastic electromagnetic pulse valve and stainless steel; for the erosion of the media must use isolation diaphragm. Example CD-F. Z3CF. Neutral medium, copper alloy should also be used as the valve material of the solenoid valve, otherwise, the valve shell often rust off, especially when the action is not frequent. Ammonia valves can not use copper. 2. Explosive environment: you must choose the appropriate level of explosion-proof products, open-air installation or dust should be more occasions use waterproof, dustproof varieties. 3. Solenoid valve nominal pressure should exceed the maximum working pressure tube. Co-use: not to use that is to spend money to buy things, but also add trouble! 1. Dielectric Characteristics 1.1 Solenoid valves of different types are selected for gas, liquid or mixed state. For example, ZQDF is used for air, ZQDF-Y is used for liquid and ZQDF-2 (or -3) is used for steam. Otherwise, it may cause malfunction . ZDF series of multi-function solenoid valve is available in the gas. Liquid. The best time to state the media state, the installation users do not have to adjust. 1.2 different medium temperature product specifications, or the coil will burn, aging seals, a serious impact on life expectancy. 1.3 Medium viscosity, usually below 50cSt. If more than this value, diameter greater than 15mm with ZDF series of multi-function electromagnetic pulse valve for special orders. Path less than 15mm set high viscosity solenoid valve. 1.4 Media cleanliness should be equipped with electromagnetic pulse valve before the recoil filter valve, the pressure is low fashion direct acting diaphragm solenoid valve for example CD-P. 1.5 If the medium is smooth and directional, and does not allow backflow ZDF-N and ZQDF-N need to use two-way flow, please make special requirements. 1.6 medium temperature should be selected within the agreed range of the solenoid valve. 2.Pipeline parameters 2.1 According to the media flow requirements and pipe connections choose the valve port and model. For example, the small diameter selection CA5 and Z3F for one pipe to two pipes, ZDF-Z1 / 2 for medium or large diameters. Another example is the control of the convergence of two pipelines, please choose ZDF-Z2 / 1. 2.2 According to the flow and the valve Kv value selected nominal diameter, but also optional with the pipe diameter. Please note that some manufacturers are not marked with Kv value, often the size of the valve hole is smaller than the interface diameter, must not be greedy price low and misleading.

Mold is a kind of industrial product that can make the material take shape in a certain way in a specific structure form.
Almost all industrial products, from airplanes and automobiles to tea cups and nails, must be moulded.
The high precision, high consistency and high productivity of moulds are incomparable to any other machining methods.
Mould determines the product quality, benefit and new product development ability to a great extent.
So the mold has the "mother of industry" honorary title.
