The spool valve is of great use to conduct experiments related to mechanical engineering. The valve also helps in the movement of oil in certain factories where the discharge outlet and the flow outlet are maintained separately. The mechanism of a spool valve is based on a cylinder inside the exterior container. There are two outlets to be used and one is often the flush instrument to drain out the fluid. The valve and the cylinders help in maintaining the spool valve regulate the flow of the said liquid. Hence the spool valve moves in only one direction.

There are several uses of the spool valve, which is of hydraulic nature. For knowing more about a spool valve, an online supplier will help you through the specifications as the listing is done in a complete form. The various kinds of spool valve along with attributes and capacity in mentioned in the online catalogue, which is helpful for the buyer. Based on the position there are two and three position spool valves and other spool ways are based on two-way valves or three way valves. Most of the spool valves are lubricated to aid in smooth flow.

The outer case of the spool valve is generally coated with a strong metal and other varieties exist in aluminum or brass when ordered specifically as these spool valves are offered as per customization. Some spool valves are also manually operable. The type of spool valve is the pneumatic spool valve. The need for lubrication here is very high as the functioning is dependent on the same.

The pneumatic spool valve also has a stick, which leads to shutting of the hose related to the valve, and also helps to open another outlet. The pneumatic spool valve, which is aided by a solenoid works on the phenomenon of an actuator, based electric charge, which activates the machine. The air pressure used also helps in the movement and control of the valve. In industrial sector the pneumatic spool valves is easily operated by a special equipment which a logic controller.
