It is the genuine Pentair part, rated at 97 psig and 8 ton.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the valve does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA heat pump makes heat by moving refrigerant through a cycle, and the expansion valve is what meters that refrigerant into the evaporator coil. Get too little through and the unit cannot absorb heat from the air; get too much and it floods. When the valve stops metering correctly the symptom is usually a heat pump that runs and runs but never brings the pool up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatch the model\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis valve is specific to the UltraTemp 120, 120C and 90I. The larger UltraTemp 140, 140C and 140HC take a different Pentair expansion valve, so check the model plate on your unit before ordering.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48633369886932,"sku":"PUR-151-4330","price":232.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1c6e0995-6178-4eca-9e11-c4a45355f6ac.jpg?v=1788798495","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-473787z-thermostatic-expansion-valve-for-ultratemp-models-120-120c-90i-heat-pumps","provider":"Active Pool Supply","version":"1.0","type":"link"}
