Industrial valves are classified in many different ways. They can be distinguished by material of construction, media handled, and/or application

Ball valves provide tight shut-off and characterizable control. They have high rangeability due to the design of the regulating element, without the complications of side loads typical of butterfly or globe valves

Butterfly valves control flow through a circular disc or vane by turning the valve's pivot axis at right angles to the direction of flow in the pipe. They are normally used as throttling valves to control flow

Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. 

Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system

Dispensing valve systems are designed to provide precise fluid dispensing depending on applications. The dispensed output can be a bead, dot, flat spray, round spray, or fill (potting). The type of dispensing pattern from dispensing valve systems is determined by valve design and is dependent on dispensed fluid properties. 

Gate valves and knife valves are linear motion valves in which a flat closure element slides into the media stream to shut off flow

Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves

Plastic valves are made from plastic materials and are used in applications that require corrosion resistance and/or chemical handling

Valve repair services repair and rebuild used valves

Emergency shut-off valves (ESV) automatically close in the event of an emergency to prevent the loss of handled media

Safety shut-off valves close a line and stop the flow of material when a pre-set condition occurs, such as excess flow, a pressure pulse from a broken line, or a temperature change from an idle burner

Single component diaphragm valves are designed to provide a precise fluid supply depending on the application. The dispensed output can be a bead, dot or fill

Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow

Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line
