Valves are devices that control flow of liquids or gases. Valves can also be hydraulic valves, pneumatic valves or electric valves as well as having an extensive selection of types including check valves, butterfly valves, globe valves, gate valves and ball valves. While valves may be used in commercial and residential applications, industrial valves are extremely popular and valve manufacturers typically construct these more heavy-duty valves from materials such as stainless steel, aluminum and brass. These items are ideal for many industries including agriculture, defense, chemical processing, power generation and petrochemical.
Pumps are essential mechanisms that are utilized in many industrial manufacturing processes. Pumps are devices used to raise, compress or transfer fluids or gases. Pumps can be hydraulic pumps, pneumatic pumps or electric pumps and include a large variety of types such as centrifugal pumps, diaphragm pumps and vacuum pumps. Pump manufacturers also mainly fabricate industrial pumps from metallic materials, but use thermoplastic and elastomeric materials such as Teflon and polypropylene as well.
In situations where a stop valve with simply on/off capabilities are required many will turn to a device known as a ball valve.
This type of valve is engineered to have a ball in the middle of the valve which either blocks the flow or allows the substance to pass through. Ball valves are designed to handle many types of materials such as liquids, gases, and suspended solids. Ball valves can also be manufactured from stainless steel, brass, plastic, cast iron and more.

There are several types of butterfly valves, each with a unique purpose. A high-performance butterfly valve is used to control the flow in systems with extremely high pressure. A pneumatic butterfly valve, on the other hand, is optimal for pressurized air systems that operate at a much lower pressure. For more complex systems, butterfly valves with multiple shut-off points are necessary. A triple offset butterfly valve provides a tighter seal because it is mounted in three positions.
Further versions of the butterfly valve use a different method of pipe connection. A flanged valve, for example, has raised edges in the enclosure so that the valve can be bolted in between two pipes. Another type of valve called a wafer butterfly valve is installed in between two flanges with nuts and bolts. A traditional valve has a manually operated control lever, but electronic controls are also possible and even desirable for automated systems. Learn More
Check valves are a type of valve that is designed to prevent unwanted to backflow and only allow materials to flow in one direction.
When the materials attempt to flow backwards the valve will then react and create a seal. Check valves are ideal not only for eliminating backflow but also for their simple design.
Although check valves come in a variety of different sizes and configurations it is hassle-free product that can be used in virtually any industry that requires reliable flow control. Learn More
Diaphragm valves are one of the many flow control devices available on the market today. They offer precision regulation to liquid, gas, and semi-solid slurry flows alike. Diaphragm valves regulate the transport of process streams by sealing process flow lines, either partially or fully, with a flexible membrane that is stretched by an actuator.
Valves may be manual, automatic, pneumatic, electric, or hydraulic. They are reliable and easy to install and maintain, and as such, they have applications in quite a few industries. These industries include agriculture, biopharmaceuticals, chemical processing, energy production, food processing, irrigation, medicine, mining, plumbing, pulp and paper, and water treatment.

The modern age of hydraulics began in the early 1600s, with the innovations of scientists like Benedetto Castelli and Blaise Pascal. It is, in fact, Pascalís law, upon which the principles of hydraulics are founded. His law states, in essence, that when pressure placed on a confined liquid increases at any point, equal and proportional increases will appear at all other points in the container.
Using this principle, engineers and scientists have successfully designed systems that generate, control, and transfer power via pressurized fluids. Hydraulic valves are an integral part of these systems, allowing for the safe and proper control of the flow and pressure of fluid within them. Learn More
A solenoid valve is a type of valve that differs from other valves as this valve utilizes electricity energy to control mechanical devices which opens and closes the valve.
One of the most common types of solenoid valves is known as the pneumatic solenoid valve which utilizes pressure to function and is very similar to a hydraulic valve. Solenoid valves are ideal in factory settings that use automation programs because the system can easily control the operations of the solenoid valves through electric currents. Learn More
Centrifugal pumps are used to increase the fluid pressure by using rotational kinetic energy. Inside the pump a rotating impeller will rotate creating energy and moving the liquid to the center of the impeller.
This causes pressure to increase downstream in a pipe and forcing the liquid to move. Generally there are several different types of pump heads associated with a centrifugal pump. These pump heads include: total dynamic, total static, static suction, static lift, static discharge, dynamic suction and dynamic lift. Learn More
All hydraulic pumps are composed in the same basic way. First, they have a reservoir, which is the section of the pump that houses stationary fluid. Next, they use hoses or tubes to transfer this fluid into the cylinder, which is the main body of the hydraulic system. Inside the cylinder, or cylinders, are found two valves and one or more pistons or gear systems. One valve is located at each end; they are called the intake check, or inlet, valve and the discharge check, or outlet, valve, respectively.
When pressurized fluid is pumped into the cylinder through the inlet, it picks up more force, which it carries over into the hydraulic system when it is released through the outlet. The role of the piston is to move or compress fluid. When the piston is withdrawn, the check valve is opened, creating a vacuum that pulls in hydraulic fluid from the reservoir. Learn More
Classified as a type of positive displacement pump, metering pumps move precise volumes of liquid in predetermined increments within specific time frames. All metering pumps can process water, but some are designed to pump other liquids, like solvents, syrups, solutions, oil, and more. When used to pump chemicals, including acids, slurries, bases, and corrosives, metering pumps may be alternatively referred to as chemical dosing devices. Other common names for metering pumps include dispensing pumps, controlled-volume pumps, and proportioning pumps.
Metering pumps encompass a large range of terms including: bellow pumps, dispensing pumps, peristaltic pumps, piston metering pumps, centrifugal pumps, and many other configurations. A metering pump controls the flow rate of a liquid and are typically designed for either variable displacement at a constant speed or fixed displacement at a variable speed. When these devices are functioning properly they will not any leakage or slippage from the input or output. Learn More
A vacuum pump is necessary for a range of industrial settings and applications. In labs, vacuum pumps help to control delicate testing environments when contaminants could destroy experiments. There are several types of vacuum pump systems, and these include: liquid ring pumps, dry pumps, oilless pumps and rotary vane pumps.
Essentially, every vacuum pump is an air pump because it moves air out of an enclosed space while also preventing it from re-entering that space. Learn More
