However, you must verify the physical pipe diameters (7\/8\" inlet and 1 1\/8\" outlet) as some older EBS series valves may have utilized different connection specifications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is external equalization necessary for a 20-ton valve?\u003c\/strong\u003e\u003cbr\u003eIn high-capacity systems, the pressure drop across the evaporator is often significant. An \u003cstrong\u003eexternally equalized thermal expansion valve\u003c\/strong\u003e senses pressure at the evaporator outlet, ensuring the valve responds to the true superheat rather than the pressure at the valve outlet.\u003c\/p\u003e\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
