QTY-15 valve features:
1, the air valve is a pneumatic control system in general and the general pneumatic tubing required to maintain a certain air pressure conditions.
2, also known as pneumatic air pressure regulator valve is direct-acting air overflow valve, which is directly operated by the handle spring regulator to regulate the output pressure, can achieve stepless voltage within a predetermined pressure range, and maintain stability in the setting value.
3, the air valve downstream pressure outlet pressure exceeds the set pressure, the relief valve start overflow, it allowed for spills of harmful gases into the air, can not directly use this product.
4, the air valve adopts balanced inlet valve, so the pressure is within the range of input change is higher than the set pressure has little effect on the output pressure.

Working temperature ° C
5 ~ 60QTY-15 valve 4.1 according to the latest supply power supply types were selected to AC and DC solenoid valves. Generally AC easy access.
4.2 voltage specification with the best preferred AC220V.DC24V.
4.3 AC power supply voltage fluctuations are usually chosen +% 10% .- 15%, DC to allow ±% 10 or so, should the ultra-poor, regulators should take measures or make special order requirements.
4.4 should be selected according to the rated current and power consumption power capacity. VA should be noted that the exchange of high value when starting, inadequate capacity should be preferred in the indirect electromagnetic valve guide.
5. Control Accuracy
5.1 ordinary electromagnetic valve only opening and closing two locations, in the control of high precision and parameters for a smooth, please choose a number of solenoid valves; Z3CF three normally open solenoid valve, with Weiqi, fully open and close three flow; ZDF -Z1 / 1 combination of multi-function solenoid valve with open, wide open, small open, open all four traffic.
5.2 Action Time: refers to connect or disconnect signal to the main valve action completion time, only the company patented products Multifunction solenoid valve for opening and closing time were adjusted, not only to meet the control accuracy requirements, but also to prevent water hammer damage.
5.3 Leakage: leakage on the sample values are given for common economic level, if too high, please make a special order.
Third, reliability: unreliable would damage the entire system
1, working life, this is not included in the factory pilot project, are type of pilot projects. To ensure the quality brand-name manufacturers should be regular elections.
2, the working standard: min long-term work, repeated short-time work and short-time working three. The company conventional products are long-term work system, that coil to allow long-term power work. For a long time the valve opening of the case is only a short time off, are advised to use a normally open solenoid valve. For use in short-time working and quantities and large, it can be used for special
