How does a thermal expansion valve work
WebApr 26, 2024 · In the automatic expansion valve, the spring pressure along with the atmospheric pressure acts on the diaphragm and pushes it down. As a result, the needle also tends to move down away from the seat leading to the opening of the valve. The evaporator pressure pushes the diaphragm in an upward direction. Due to this, the needle … WebThermal Expansion Relief Valve. SKU 25704LF. SharkBite's Thermal Expansion Relief Valve eliminates the need for an expansion tank, shut-off valve and fitting. Features a pressure-only safety relief valve designed to protect hot water supply systems where high pressure conditions are likely to occur as a result of thermal expansion.
