What is a cartridge valve?
Cartridge Valves, also known as 2/2-way valves or logic elements, are industrial hydraulic valves used for directional, pressure, check, and flow control. These cartridge valves are a compact design that can be used in hydraulic manifold systems for many types of industrial and mobile machinery.
What is pneumatic on off valve?
Pneumatic Shut Off Valves in Systems Pneumatic shut off valves are used in a variety of industries and can be used to control the flow of gases and liquids at a high pressure or in industries that deal with compressed atmospheric air. An electrical or manual system can power them.
What is a pneumatic pilot valve?
Air pilot operated pneumatic valves control compressed air within pneumatic systems; they are used to signal valves, cylinders or other pneumatic devices. Pilot operated pneumatic valves are available as a 3 or 5-way valve configuration with G1/8, G1/4 or G1/2 threaded ports.
What is slip in cartridge valve?
Slip-In Type Cartridge Valves Slip-in cartridge valves typically consist of a valve sleeve, poppet and spring. They slip into the manifold block and are held in by a cover plate that bolts on to the manifold, which seals it off.
What is the purpose of cartridge valve hydraulic?
Cartridge valves (known also as 2/2-way valves) internally regulate the direction, pressure, and/or flow control of hydraulic systems. They are a type of inline valve, meaning they act parallel to the flow of fluid, and are best used when high flow rates and leak-free control is necessary.
What is a cartridge solenoid?
Cartridge solenoid valve will control which element the hydraulic fluid will flow to. Normally, valve designed with coil and cartridge spool or poppet . The valve is generally specified by number of positions and number of ways (ports). The valve is made up of two parts, the body and the spool.
Why are pneumatic valves used?
In the first context, a pneumatic valve is a mechanism that is used to modulate or control the flow of air (or another gas) in a pneumatic system. They work by controlling the air or gas at the source, regulating its passage as needed into pipes, tubing, or devices in an automatic pneumatic system.
How do pneumatic valve springs work?
The pneumatic “spring” utilizes the elastic effect obtained when a volume of air is compressed. In short, a small cylinder of air is created under the valve retainer that, when compressed by the opening valve, generates the closing force. The “spring” can be easily tuned to have different characteristics.
What are the types of pneumatic valves?
The primary types of Pneumatic valves you’ll find are:
- Two-way directional control valves.
- Three-way directional valves.
- Four-way directional valves.
- Spring offset pneumatic valves.
What is an internal pilot valve?
Internal Pilot Operated Valves – This type of valve is provided with a 2-Way pilot solenoid operator. A diaphragm or piston provides the seal for the main seat. These valves are used for switching pressures in conjunction with orifice sizes larger than those available with direct-acting valves.
Which is a logic valve?
Logic valves are essentially high flow poppet or spool elements that are controlled by small pilot devices. They can be used to control flow, pressure, or direction, and when applied in the proper arrangements, can perform multi-task control functions.
What is the meaning of cartridge in history?
: a case or container that holds a substance, device, or material which is difficult, troublesome, or awkward to handle and that usually can be easily changed: such as. a : a tube (as of metal) containing a complete charge for a firearm and usually an initiating device (such as a primer)
What is hydraulic cartridge valves?
Hydraulic Cartridge Valves. The Sun hydraulic valves are manufactured as a 2-piece screw-in cartridge where all the moving parts are contained in the bottom section of the cartridge. This allows unbinding movement, if the threaded section of the cavity is misaligned with the drilled and bored section of the cavity.
What is a pneumatic check valve?
Pneumatic Check Valves. A pneumatic check valve from Grainger can allow air to flow through your air compressor in one direction and prevent compressed air from flowing back into it, helping compressors to keep certain parts pressurized and others depressurized.
What is a pneumatic flow control valve?
Flow Control Valves are used to reduce the rate of flow in a section of a pneumatic circuit, resulting in a slower actuator speed. Unlike a Needle Valve, a Flow Control Valve regulates air flow in only one direction, allowing free flow in the opposite direction.
