Does a pneumatic spool valve require lubrication?
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 date did Harrison lingle invente the pneumatic?
Apparently no one knows...
What is the advantage of Pneumatic tires?
One answer is that the tire is made from reinforced rubber, which is very friendly to the environment.
What is a non-positive shut off valve?
A non-positive shut off valve is one that is controlled by the user. You hold down the valve to keep the water or whatever coming out, and when you want it to stop, you release the valve.
Which valve is the preferred valve to use as flow control valve at the pump discharge 8 inch size ball valve can be used for the same application?
I would use a butterfly valve to set the flow and a pitot tube to measure it. Nexus Valve makes a good one and it is price competetive as well.

How do you prevent back flow of water from a tank?
You can prevent back flow of water from your tank by installing a back flow restrictor valve. The restrictor valve will allow fluid to flow in one direction.
What are the Application of control valve with positioner?
One of the application of the control valve with positioner is that it is used to control the opening and closing of the actuator based on electric or pneumatic signals. The opening or closing of control valves is usually done automatically by electrical, hydraulic or pneumatic actuators.
How does a 4 way pneumatic valve work?
Moduflex dual valve combines two, 4-way valves into one valve body, it features two independently operated valves in the Size 1 valve body. :)
What is the function of the one way valve?
construction of one way valve brake system..
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 expansion valve?
The function of an expansion valve is to regulate the flow of a substance. One example is a thermal expansion valve which regulates the flow of cooling substances within a device.
What are some examples of pneumatic devices?
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
How AND valve in pneumatic system operate?
It is similar to logic gate AND. One out put with two inputs. Output is true when both inputs are true the valve has two air inputs. Valve operates only when both the input air are present. Valve wont operate with any one air input.
Check valve function?
A check valve or one-way valve enables fluids to flow through in a single direction.
