Engine valves are one of the most important components of a functioning automotive engine.
Investing in quality engine valves is essential for ensuring that your engine operates efficiently and reliably.
Automotive engine valves are responsible for controlling the flow of air and fuel into and out of the cylinders of a running engine.
Engine valves open and close as the engine runs, creating a combustion stroke and allowing the engine to power your car.
Quality engine valves ensure that these strokes are properly regulated and that only the right amount of fuel and air mix is admitted into the engine.
Choosing the right engine valves for your specific engine will allow it to reach its full potential in terms of efficiency and power delivery.
We’re here to provide you with the best quality engine valves so you can get the most out of your engine.
Q: What are Engine Valves?
A: Engine valves are basically control points for the flow of fuel and exhaust gases in and out of the combustion chamber in an engine. Each cylinder in an engine requires two valves - one for intake, and one for exhaust - that open and close at the precise moment required of them.
Q: How do Engine Valves Work?
A: In internal combustion engines, the engine valves are driven by a camshaft, rotating mechanical device that shifts the valves. The camshaft is connected to the crankshaft, and when the crankshaft spins, it causes the camshaft to rotate, thus moving the valves in a series of events to allow the intake and exhaust gases to flow into and out of the combustion chamber.
Q: What are the Different Types of Engine Valves?
A: The type of engine valve used in an engine depends on the type of engine. There are poppet valves, rotary valves and overhead camshafts. Poppet valves are the most common type of engine valve, and are made up of a moving part called the valve head, and a stationary seat. Rotary valves consist of a rotating part called the rotor, which is used to control the opening and closing of the valve. Finally, overhead camshafts are actuated by rockers and are used in most modern engines.

Ring RTC Tyre inflator
Bought the tyre inflator because of the unreliable service station tyre inflators.
The buying process online through APD was straightforward. Ordered the tyre inflator late afternoon and received it 2 days later via the Royal mail.
I have a car, campervan and motorbike. I like the wind in cable feature keeps everything neat and tidy. The inflator is easy to use on all three vehicles. Appreciated the chocolate.
Very quick despatch and delivery time
Good updates. Items exactly as described. All fitted and car back on the road.
Personally I found them to be very...
helpful response to emails relating to my purchase was within the hour and they offered the best price on the parts I needed had to wait a couple of days longer than usual due to the parts that I needed was out of stock (but I was made aware of this before ordering) would happily use them again.
Very helpful company.
I ordered a cabin filter on their website which was out of stock. They contacted me by email & offered a replacement which wasn't really what I wanted so they immediately sent a refund. I found another that was suitable, they happily ordered it for me and called me when it arrived in my local store to collect.
Helpful people giving great service
The Wiper blades I ordered were competitively priced and promptly delivered. Unfortunately there was an issue with the fitment and this is where APD showed their commitment to great customer service. They were most helpful in resolving the problem to my complete satisfaction.
