They remove pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator. Expansion valves serve two purposes: controlling the amount of refrigerant entering the evaporator and maintaining the pressure difference between the condenser (high-pressure side) and the evaporator (low-pressure side).

Thermal Expansion Valves<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">\u00a0A <a href=\"https:\/\/en.wikipedia.org\/wiki\/Thermal_expansion_valve\" target=\"_blank\" rel=\"noopener noreferrer\">thermal expansion valve<\/a> or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a device that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the vapor leaving the evaporator. Although often described as a &#8220;thermostatic&#8221; valve, an expansion valve does not regulate temperature; the temperature of the evaporator will vary with the evaporation pressure.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These <\/span><span style=\"font-weight: 400;\">types of expansion valves<\/span><span style=\"font-weight: 400;\"> are popular due to their simplicity and availability, and their relatively good sensitivity and accuracy in regulation. The large choice of expansion valve sizes and bulb charges means the capacity and temperature ranges are very good. The disadvantage of TEVs is the necessity for relatively high superheating, which steals the heat transfer area from the evaporation process.<\/span><\/p>\n<figure id=\"attachment_17273\" aria-describedby=\"caption-attachment-17273\" style=\"width: 1200px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-17273\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/1200px-Thermostatic_expansion_valve.svg_.png\" alt=\"Types of Expansion Valves\" width=\"1200\" height=\"1150\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/1200px-Thermostatic_expansion_valve.svg_.png 1200w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/1200px-Thermostatic_expansion_valve.svg_-300x288.png 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/1200px-Thermostatic_expansion_valve.svg_-1024x981.png 1024w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/1200px-Thermostatic_expansion_valve.svg_-768x736.png 768w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><figcaption id=\"caption-attachment-17273\" class=\"wp-caption-text\">Parts of a thermal expansion valve (Reference: <strong>en.wikipedia.org<\/strong>)<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400;\">The TEV strives to maintain a stable level of superheating inside the evaporator under all conditions by adjusting the mass flow of refrigerant in response to the evaporator load. This is achieved by a membrane inside the valve housing, which compares the temperature before and after the evaporator. To be able to compare the pressures before and after the evaporator, the TEV has to be combined with another device, a bulb. The difference in pressure between the saturation pressure of evaporation and the pressure of the bulb is balanced across a membrane inside the head of the valve. The movement of the membrane controls the position of a needle and hence the mass flow of refrigerant entering the evaporator.<\/span><\/p>\n<p style=\"text-align: center;\"><span style=\"text-decoration: underline;\"><a href=\"https:\/\/www.linquip.com\/industrial-directories\/836\/actuator\/for-sale?utm_source=blog&amp;utm_medium=content&amp;utm_campaign=CRO&amp;utm_term=expansion_valve_types&amp;utm_content=for_sale\" target=\"_blank\" rel=\"noopener\"><strong>See All Actuator Valve for Sale<\/strong><\/a><\/span><\/p>\n<h3><strong>2.

The needle position is fixed, and the mass flow through it depends on the pressure difference across the valve. The hand expansion valve is normally used as a supplementary safety valve installed in a bypass line. It is also commonly used to control the flow rate through oil bleeder lines. The manual expansion valve is non-regulating and should not be used as an expansion valve with a BPHE evaporator, because any changes in operating conditions would instantly change the evaporation process inside the rapidly responding plate heat exchanger. Regulating the flow manually would require immediate adjustment, which is not practically feasible.\u200b\u200b<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These <\/span><span style=\"font-weight: 400;\">types of expansion valves<\/span><span style=\"font-weight: 400;\"> have the disadvantage of being unresponsive to changes in load or seawater temperature and must be adjusted frequently. The valve itself is a screw-down needle valve dimensioned to give fine adjustment.<\/span><\/p>\n<figure id=\"attachment_17274\" aria-describedby=\"caption-attachment-17274\" style=\"width: 355px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-17274\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/handexpansionvalve.jpg\" alt=\"Types of Expansion Valves\" width=\"355\" height=\"450\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/handexpansionvalve.jpg 355w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/handexpansionvalve-237x300.jpg 237w\" sizes=\"(max-width: 355px) 100vw, 355px\" \/><figcaption id=\"caption-attachment-17274\" class=\"wp-caption-text\">Manual expansion valve (Reference: <strong>campbell-sevey.com<\/strong>)<\/figcaption><\/figure>\n<h3><strong>3.

They do this in response to signals sent to them by an electronic controller. A small motor is used to open and close the valve port that is called a step or a stepper motor. Step motors do not rotate continuously; they are controlled by an electronic controller and rotate a fraction of a revolution for each signal sent to them by the electronic controller. The step motor is driven by a gear train, which positions a pin in a port in which refrigerant flows.<\/span><\/p>\n<figure id=\"attachment_17277\" aria-describedby=\"caption-attachment-17277\" style=\"width: 902px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-17277\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/thermal-vs-electronic.png\" alt=\"Types of Expansion Valves\" width=\"902\" height=\"434\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/thermal-vs-electronic.png 902w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/thermal-vs-electronic-300x144.png 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/09\/thermal-vs-electronic-768x370.png 768w\" sizes=\"(max-width: 902px) 100vw, 902px\" \/><figcaption id=\"caption-attachment-17277\" class=\"wp-caption-text\">A comparison between thermal and electronic expansion valves (Reference: <strong>no.pinterest.com<\/strong>)<\/figcaption><\/figure>\n<h3><strong>6. Float Valves<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">The Float Valve operates by a float immersed in the liquid refrigerant. Both low-side float and high side-float are devices used to control the flow of liquid refrigerant.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The low-side float valve helps maintain a constant level of liquid refrigerant in the evaporator. It opens when there is no liquid in the evaporator and closes when there is liquid in the evaporator.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The high-side float valve is located at the high-pressure side of the system that maintains a constant level of refrigerant in the condenser. When the compressor operates, the condensed refrigerant flows to the float chamber and opens the valve.<\/span><\/p>\n<p style=\"text-align: center;\"><span style=\"text-decoration: underline;\"><a href=\"https:\/\/www.linquip.com\/industrial-directories\/997\/bleeder-valve\/for-sale?utm_source=blog&amp;utm_medium=content&amp;utm_campaign=CRO&amp;utm_term=expansion_valve_types&amp;utm_content=for_sale\" target=\"_blank\" rel=\"noopener\"><strong>See All Bleeder Valve for Sale<\/strong><\/a><\/span><\/p>\n<p><span style=\"font-weight: 400;\">This causes the refrigerant to flow into the evaporator where it is stored.
