A pneumatic spool valve usually has two sets of atleast one but possibly more rubber o-rings which does indeed need lubrication to function properly.

What is a hydraulic detent valve?
A spring device which maintains the spool of a directional control valve in position.
Are all air valves pneumatic?
Pneumatic is defined as air driven and therefore the two terms are synonomous. However pneumatic is not as frequently used in describing a valve.
What is the definition of pneumatic valve?
A valve which requires pressurised air to operate (open or close) is known as pneumatic valve. A valve has a valve base through which the media (could be be air, liquid, steam, gas...) flows and a actuator mounted on the base which helps operate the valve. This actuator could be of pneumatic type. (or elctrically operated motorised type)
For what purpose is a pneumatic valve used?
Pneumatic valves are used to close valves in high-speed internal combustion engines, pneumatic valves are mostly to help racing engines to get to high speeds.
What is a spool type hydraulic valve used to control?
Hydraulic actuators. Also called hydraulic rams or hydraulic cylinders.
What is a pneumatic solenoid operated spool valve?
spool valveA spool valve is a multidirectional hydraulic or pneumatic valve usually operated by a joystick. It has several hoses attached to it leading to different pneumatic rams. When the joystick is pushed in one direction, it causes the valve to shut off one of the pneumatic hoses leading to the ram and open the other. Which way the joystick is pushed moves the piston in the ram in or out. Since you specified a solenoid operated valve it is operated not by a joystick that is directly connected to the valve but rather an electric joystick like the you would use in a video game and an electrical signal is sent to activate a solenoid that does the same thing but can be much farther away from the operator. Solenoid Actuated Pneumatic Spool ValveA solenoid actuated pneumatic spool valve is a spool valve actuated by an electric solenoid. They are often used in industrial automation and are usually controlled by a PC or a PLC (Programmable Logic Controller) rather than a manual switch. To reduce the size and power consumption of the solenoid, often the solenoid does not directly actuate the spool. Instead, the solenoid actuates a small internal valve which directs upstream air pressure to move the spool. This is called an air piloted solenoid actuated pneumatic spool valve. The air pilot mechanism typically requires about 40 PSI to operate reliably. If the air pressure upstream of the valve is going to be less than 40 PSI, the valve must be externally piloted, meaning that the pilot is connected to a separate air source which is above 40 PSI.
What is the function of pneumatic valves?
If you are talking about a pneumatic solenoid valve the function of it is to control the air in and out flow in a pneumatic actuator.
What is a hydraulic detent valve?
A spring device which maintains the spool of a directional control valve in position.
How does a directional control valve work?
Directional control valves are one of the most fundamental parts in hydraulic as well and pneumatic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a spool inside a cylinder which is mechanically or electrically controlled. The movement of the spool restricts or permits the flow, thus it controls the fluid flow.
Is the ion xe spool or poppet valve?
Spool. you can tell easily between spool and poppet, because a poppet valve has a visible bolt with a cocking lever on in, whereas spools have no external bolt. Look ate the planet eclipese EGO and the GEO and you will see what i mean.

What is the principle of positioner in control valve?
to amplify the input pneumatic signal
Arms wont lift up or down on Bobcat 873?
this can be caused by a number of things * low oil level *damaged hydraulic pump *sticking or spool valve *worn valve body *damaged anticavity solenoid valve *damaged lift spool lock solenoid
