They are also used to control or regulate the flow of solids to and from process units, storage bins, [[Conveyors]] and product packaging. There are several basic types of solids valves. Ball valves provide tight shut off, predictable control, and ease of operation. 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 &lt;/ins&gt;the &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;pipe&lt;/ins&gt;. &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;Clamshell valves &lt;/ins&gt;use &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;a swinging disc or gate to cutoff, restrict, or control the flow path. [[Control Valves]] or proportional valves are power-operated devices that modify fluid flow or pressure rate in a process system. [[Diverter Valves]] change the direction of the flow &lt;/ins&gt;of &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;a medium &lt;/ins&gt;to &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;two or more different directions&lt;/ins&gt;. &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;Double flap airlocks and flap valves are used to shut-off the flow of bulk material. The flaps open sequentially to maintain the airlock between &lt;/ins&gt;the &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;hopper and conveyor or process unit. Iris valves enclose mechanical components in a flexible sleeve to prevent &lt;/ins&gt;the &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;ingress of solid materials&lt;/ins&gt;. &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;Mixing valves combine &lt;/ins&gt;the &lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;flows of two or more inlets into a single outlet. Pinch valves are full bore, linear action valves used for on&lt;/ins&gt;/&lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;off control or throttling service. Gate valves or knife valves are solids valves that use a flat closure element to provide shut-off.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Valve size represents the size of the passage opening and is measured in English units such as inches (in) or metric units such as centimeters (cm). Pressure rating is the maximum pressure, usually measured in pounds per square inch (psi), for which products are rated. There are many different actuation methods for solids valves. Manual devices are opened or closed via a hand&lt;/ins&gt;-&lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;operated wheel or crank. Mechanical valves are actuated by an unpowered component such as a float or cam. Electric and [[Pneumatic Valves]] are commonly available. Electro&lt;/ins&gt;-&lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;hydraulic servo valves produce hydraulic control in response to an electrical signal input. Similarly, electro&lt;/ins&gt;-&lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;pneumatic servo valves produce pneumatic control in response to an electrical signal input. Thermally&lt;/ins&gt;-&lt;ins style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;actuated valves are activated by a change in temperature in the handled media. Typically, temperature and pressure relief occurs once a preset temperature is reached.  &lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
