The advantage of Cartridge Valve is better than conventional cemented with Subplate – mounted as follows.
   1. The design is flexible.
   2. Price of installation under
   3. Smaller.
   4. The features and better control.
   5. Secure.
   6. The pressure over
   7. The work more efficient.
   8. Can differentiate between leakage and external leakage and internal leakage.
   9. The time of each stroke is faster.
   10. Noise less than

   The primary function of that type of Cartridge Valve Slip – in.
   The work of this type of valve is similar to a Poppet check valve, which consists of the inserted pieces into a room of Manifold.

Cartrid Valve Detail

   Components of the Cartridge. Valve type that slip – in.

   To separate the major components is broken down. The valve to an external oil 2 channel is channel A and channel B will penetrate through the clot Man New workflow express the channel A and channel B to the rest of the system intended to be a channel bottleneck is to reduce speed. When the valve opens and closes, which in many sizes to choose from. Each size is associated with the work so the designer can reduce the Shock that occurs in the system to a minimum.

   Use of force and open the valve closed.
   Force for closing the valve caused the pressure acting on the AAP area, plus the force of the spring force to open the valve to the pressure. Made to the area of the box A and box B if the sum of the forces that close the valve more than the sum of the forces that open the valve. This valve will close in nature. And vice versa. If the sum of the forces that open the valve more than the sum of the forces that close the valve. Valves are open in nature.

Simple system with cartrid valve

     Example circuit.

   Figure HYDRO-CARTRIDGE-2. An example circuit for area 1: 2 and 40 pound spring force in this circuit will make oil go in Cartridge Valve cylinder through that area will notice that the AP is connected by pipes to the fuel tank through a DC power valve so that the valve is closed by spring force alone. If the pressure of the pressure cylinder was 1,000 pounds per square inch, it means that the pressure at Area A was 1,000 pounds per square inch, and area B were 1,000 pounds per square inch and the area of AP equal to zero if it is calculated that the valve closed or Open the following can be done.

   Assume that.
   AAP = 2 square inches.
   AA = 1 square inch
   AB = 1 square inch
   The valve closing force (Fc) = 40 pounds (0 pounds per square inch) = 40 lbs.
   Force the valve open (Fo) = (1,000 pounds per square inch x 1 inch) (1,000 pounds per square inch x 1 inch).
   Force the valve open (Fo) = 2,000 pounds per square inch.

   The various problems found in hydraulic a like pipe Hydrualic usually cause oil leakage at the joints various later also developed using Manifold Block to reduce the number of joints are for use to solve the problem of leakage. oil from the joints of pipe or a one.

A seal damaged or missing piston alone can not be held responsible for the creeping stem of the cylinder, the seal gland end of the rod must also be damaged and leakage at the same time.

If the seal gland is damaged, then steals the stem downward by gravity and a heavy load, can make up fluid to start the vacuum that rod out of the cylinder, and moves in the free atmosphere. The presence of this liquid makeup can explore. Without it, the solution would be to create a team of space they would keep in place.

In this case, the makeup air is. The air is indeed a very useful liquid (no liquid) for use in bottles, especially if you do not mind vague, non-positive movement, and you do not operate at high pressures.

If the pole is pointing up or down, we learned that the lack of piston seal will not let blocked on a single rod cylinder with cylinder fluid drive or ports when the seal gland is rampant compromised.

If you know that your bottle is, in fact, if the ports seem to slip around the directional valve, and yet the end of the rod gland seal leakage is not allowed, where are the real cause?

The check valve of the management itself is often the cause. It can not be closed, the “A” and “B” cylinder ports operate completely. The valve may be worn or it is not because of his return to the position half-closed. The cause of valve problems will be covered in future newsletters.

An altitude valve controls the level of a reservoir. The altitude valve will remain open while the tank is not full and will be closed when the reservoir reaches its maximum level. The opening and closing the valve requires no external power source (electric, pneumatic or power of man), it was done automatically, hence its name.
Control Valves
A control valve regulates the flow or fluid pressure. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. The control valves are normally fitted with actuators and positioners. Globe valves are widely used tire for control in many sectors, although quarter-turn types such as (amended), ball and butterfly valves are also used.
Regulation of the valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as Automatic Control Valves. Hydraulic actuators in response to changes in pressure or flow, and open / close the valve. Valves automatiche di controllo non richiedono Sorgente di una alimentazione esterna, il che significa che la pressione del fluido è sufficiente per aprire e chiudere the valvola. Automatic control valves include: pressure reducers, valves, flow control, back support pressure valve, altitude valves and safety valves. An altitude valve controls the level of a reservoir. The altitude valve will remain open while the tank is not full and will be closed when the reservoir reaches its maximum level. The opening and closing the valve requires no external power source (electric, pneumatic or power of man), it was done automatically, hence its name.
