Rexroth Solenoid Valve Z2S22-1-51 For Long Working Life AC/DC Power

Product Description

4. Power supply conditions1) According to the type of power supply, choose AC and DC solenoid valves respectively. Generally speaking, AC power supply is easy to access;2) For voltage specifications, AC220V.DC24V is preferred;3) Power supply voltage fluctuation usually AC selection +%10% -15%, DC allowed ±% 10% or so, if out of tolerance, must take voltage regulation measures;4) The rated current and power consumption should be selected according to the power supply capacity. It should be noted that the VA value is high when AC starting, and the indirect pilot solenoid valve should be preferred when the capacity is insufficient.5. Control accuracy1) Ordinary solenoid valve only open, close two positions, in the control accuracy requirements of high and stable parameters need to choose a multi-digit solenoid valve;2) Operation time: refers to the time when the electrical signal is connected or cut off to the completion of the main valve action;3) Leakage: The leakage value given on the sample is a common economic grade.

Reliability:1, working life, this is not included in the factory test project, belongs to the type test project. In order to ensure the quality should choose regular manufacturers of brand-name products.2, working system: divided into long-term working system, repeated short-time working system and short-time working system three. If the valve is opened for a long time and only closed for a short time, the normally open solenoid valve should be selected.3, working frequency: When the operation frequency is high, the structure should be preferred direct acting solenoid valve, and the power supply is preferred AC.4, action reliabilityStrictly speaking, this test has not been officially included in China's solenoid valve professional standards, in order to ensure the quality of regular manufacturers should choose brand-name products. In some cases, the number of movements is not much, but the reliability requirements are very high, such as fire protection, emergency protection, etc., must not be taken lightly. It is particularly important to take two simultaneous double insurance.Economy:It is one of the scales chosen, but must be economical on a safe, applicable and reliable basis.
Economy is not only the price of the product, but also the cost of its function and quality as well as installation and maintenance and other accessories.More importantly, a solenoid valve in the entire automatic control system in the entire automatic control system and even in the production line accounted for very little cost, if the greed of small and cheap wrong selection caused by the damage group is huge.
