Industrial valves are classified in many different ways. They can be distinguished by material of construction, media handled, and/or application. Most industrial valves are made of metal or plastic materials. Metal valves are made of aluminum, brass, bronze, copper, cast iron, ductile iron, steel, or stainless steel. Plastic valves are made of acetal polymers, polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), polyethylene (PE), polypropylene (PP), or polyvinylidene fluoride (PVDF). In terms of media handled, there are many choices for industrial valves. Air valves can handle breathable, compressed, or non-pressurized air. Water valves can handle hot water, cold water, ground water, potable water, salt water, or wastewater. Gas valves can handle high-purity gas, liquefied petroleum (LP), natural gas, or sour gas. Some industrial valves can handle abrasive materials, acids, adhesives, concrete, coolants, hazardous materials, high viscosity fluids, hydraulic fluids, or gasoline. Others are designed to handle liquid metal, lubricants, oil, powders, rendering wastes, solids, sludge, slurry, or steam.

Products & Services Related to Industrial Valves
Air Pressure Regulators
Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices.
Air Valves
Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.
Control Valves
Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system.
Diaphragm Valves
Diaphragm valves close by means of a flexible diaphragm attached to a compressor.
Plastic Valves
Plastic valves are made from plastic materials and are used in applications that require corrosion resistance and/or chemical handling.
Pressure Regulators
Pressure regulators are used to maintain a constant outlet pressure or flow.
Sanitary Valves
Sanitary valves are designed for applications requiring clean or sterile processing.
