What is the function of valves

AND valves - explanation of use and function

AND valves are used wherever a logical AND link is important in pneumatic and hydraulic circuits. Because the system operator has to operate them at the same time when operating a pneumatic or hydraulic system, these valves are not insignificant for safety. This prevents the operator from reaching into the machine during operation. In the following video, our experts explain the use and function of the valves to you.

The AND valves, also known as AND valves, are two-pressure valves. These valves have two input signals and only one output signal. Accordingly, you have to hold both input signals permanently to enable the output.

We will show you how this valve works using a practical structure. Applied in this way, however, it does not meet any safety guidelines. However, our expert also offers you a solution here and explains how you can achieve these guidelines.

Here you can find the articles from the video:

You can also watch an interesting video on OR valves. In addition, you will find a huge selection of other pneumatic and hydraulic components and elements in our online shop.

I have never seen a better online shop. This is just insane.

Fast delivery service, absolutely great that you can get O-rings individually! Tool "lifting set" flawless.

Delivery with GLS unacceptable. Had the part ordered to my address as the delivery address. There cannot have been an attempt to deliver to my address, as I did not leave the house all day and there was also no message in the mailbox. Since the parcel did not arrive, I did some research today and found that the parcel had already been delivered to the parcel shop on Friday. A message to me “No return” Collection possible again from Monday. Conclusion: company ok. If I pay € 7.50 to order a part of approx. 200 g, but then need another 30-45 minutes for the unwanted collection (because the delivery service is not able to work correctly), then I can do it unfortunately no longer order. Addendum: Since the evaluation is an assessment of the company, I have corrected my information. Order process was ok. My question was answered immediately. Therefore there is nothing to complain about on the site. Conclusion: 5 stars instead of 1 star and I would order there again. Nothing has changed about my attitude towards the delivery service.

I bought accessories like safety valve etc. for the compressor. I have to say it all worked very well. I am more than satisfied and can only recommend it.

After the first difficulties I gave my first review, whereupon the company immediately contacted me and met me with full confidence. I can only apologize for my first review and can only recommend it

Torben Möller
Extremely good service, excellent customer support, Mr. Hoppe takes great care of his customers. I am very enthusiastic, I would like to experience something like this more often. Actually, 5 stars are not enough.
Thorsten Knefel
Super professional service. 1A telephone support from people who are really familiar with the subject and who take the time to give advice, even for small orders. Website super clear, very well functioning order process, free shipping where various parcel service providers are possible. Own YouTube channel where the technology is explained. Delivery and ordering is very quick. Is like a specialist retailer as you know it from before, only in large size. Absolutely perfect, more service and quality is not possible. It's rare today. A specialist shop where you still know the word Kaufmansehre. Absolutely recommendable.

Ordered two valves 2 days ago and received an email today that the order had been removed from the system. I should order again from a representative nearby. Thank you very much. ADDENDUM: Today I received a nice, friendly explanation from the Landefeld company about a misunderstanding during processing. Great respect for this personal customer service and that is why I am of course very happy to accept your apology!
Gerd Winter
Very fast delivery of the ordered goods. A defective part was replaced immediately. Nice and friendly contact. Customer service is still very important here.

So far we have only had very good experiences with the Landefeld company. The online shop is well structured, you don't have to search forever and lose valuable time. The prices are acceptable and the delivery times almost unbeatable.
