One of the most common pneumatic control valve designs is the poppet valve. The pneumatic poppet valve consists of a hole that is opened and closed by raising and lowering the sealing surface of the hole. It usually has an internal spring that holds the valve in a closed position. When the spring force is overcome, the sealing surface breaks away from the bore and the valve opens.

Today we will tell you about what a Univer poppet valve is, what types of such valves exist, and where they are used.

What is Univer Poppet Valve?

Pneumatic poppet valves are often used in engines and other fast-reacting processes due to the fact that the poppet valve is a high-capacity fast-acting valve.

Poppet valves are directional control valves with large flow paths to allow media to pass through the main poppet valve body. A good way to describe how a poppet valve works is to think of the valve as a plug in a sink. Removing the plug allows the flow path to be quickly opened, making the hole larger. In the case of a poppet valve, this large orifice allows the medium to pass quickly and efficiently through the valve.

Such valves are needed for the inlet and outlet of various working media into the cylinders. They block and open highways, ensuring the smooth operation of mechanisms, but, more importantly, preventing unnecessary media from entering parts of the system that were not intended for them.

This type of valve works as follows:

  • It consists of a locking plate that covers the gate, a pair of washers, a spring, and sealing rings. This is a fairly simple and very effective design, the main advantage of which is the minimum number of moving parts. This means the minimum number of potential places for future breakdowns.
  • Depending on the installation location, the valve opens in one phase and closes in another. Moreover, he does it on his own, thanks to the well-thought-out physics of the mechanism: due to its weight and the pressure created by the piston.
  • Thanks to precise manufacturing and quality sealing, the valve seals the cylinder when closed, protecting it from the unplanned supply of the working medium, and allowing you to create the necessary working pressure.

There are two such valves on each cylinder, they are installed in a mirror: one on the inlet line, and the other on the outlet. They open in different directions, and therefore when one is open, the other is always tightly closed.

What are the Types of Univer Poppet Valves?

There are two types of pneumatic engine poppet valves which we will tell you about below.

Poppet valve with ball seat

In this type, a ball is used to stop the flow, poppet valves are normally closed valves, and ball valves are usually 2/2-way control valves. The sealing characteristics of this valve are very good, so it can be used as a shut-off valve. The ball will move from its place when you press the button. The ball will be lifted from its place and the flow will take place. If the button is released, the ball will block the flow using air pressure and a spring.

Disc seat poppet valve

This type of poppet valve uses a disc to stop the flow and this valve is a 3/2-way control valve. Thus, in this type, when the button is released, the R and P ports will be connected. Thus, if the button is pressed, port R will be blocked by the valve stem and push the disc down, thus opening the valve. Thus, ports P and R have established a connection. To close the valve, release the button and the P port will be closed by the spring and thus close the valve.
