: This valve is operated manually, and is used to regulate fluid flow in pipes. The design consists of outlet openings, which are oriented to the inlet openings at right angles. Angle valves are sub-typed into cage-style and disk stack style valves.
: This valve type is used to regulate pipeline flows. The design comprises a spherical body, with the two halves separated by a baffle. The valve has an opening where a movable disk or plug is placed to close the valve. Globe valves can be designed in single-port, three-way, port-guided, double-ported, high capacity cage-guided, and balanced-plug cage-style bodies.
: Rotary valves consist of transverse plugs, which rotate, thus allowing for flow regulation of gases or liquids. They are mainly used in steam and gas engines, and in industrial furnaces.
: Also known as membrane valves, diaphragm valves are designed with multiple ports. The diaphragm that closes the valve is located on top of a weir, or saddle. The design can include pneumatic, electric, hydraulic, or even manual actuators. Valves with two port bodies are known as 2/2-way valves, while bodies with three ports are called 3/2, or T valves. Bodies with more than three ports are called block valves.
: As the name suggests, this valve type utilizes air pressure to produce linear or circular movements. The valve is supported by a piston or diaphragm. Air Operated valves can be designed as 2-way, 3-way, and 4-way valves. Sub-types include relay and pinch valves.
: This type of valve is primarily used in applications involving steam engines. It helps control the amount of steam that goes into the engine. It is also used to control exhaust emissions. They slide from side to side, moving with other moving parts to control the steam and exhaust. Today, sliding cylinder valves are used in automobiles to control the intake of gas in engines.
: These valves are controlled by pneumatic actuators. The design includes a piston actuator, which is used to provide linear movements to lift seals. Angle valves are primarily used in applications consisting of high flow rates and temperatures.
