The valve has an integrated shut-off\/check valve which ­ensures opening even at low pressure differences. The check valve is inspection able and classified as a back flow preventer Type EA, fluid category 1-2, according to EN 1717.\u003cbr\u003e\u003cbr\u003eThe arrow on the valve body indicates the direction of the flow.\u003c\/p\u003e\n\u003cp\u003eMale threads are sealed in the usual manner. Both the inlet side as well as the outlet side are designed according to the LK Armatur O-ring seal system. When connecting to this system, tighten first by hand until stop, then another 0.5-1.5 turns with an appropriate tool into the right position.\u003cbr\u003e\u003cbr\u003eIt is easier to fit the compression fitting if a lubricant is applied to the thread and bevel. Tighten first by hand and then with a box spanner. Number of turns to be tightened with a spanner: See the separate datasheet for compression fittings. Soft pipes are to be fitted with a support sleeve.\u003c\/p\u003e\n\u003cp\u003eThe valve requires no maintenance but the installation should be checked regularly.\u003c\/p\u003e","brand":"LK","offers":[{"title":"090268 - DIM M½\" KVS M³\/H 2.7 - Male Thread","offer_id":55181157106040,"sku":"090268","price":41.95,"currency_code":"EUR","in_stock":true},{"title":"090271 - DIM M15mm KVS M³\/H 2.7 - Compression","offer_id":55181157138808,"sku":"090271","price":48.95,"currency_code":"EUR","in_stock":true},{"title":"090269 - DIM M½\"\/15mm KVS M³\/H 2.7 - Male \u0026 Compression","offer_id":55181157171576,"sku":"090269","price":46.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0799\/5523\/1002\/files\/lk-538-thermofill-ea-_male.jpg?v=1751037020","url":"https:\/\/heatpumpparts.eu\/products\/lk-538-thermofill%c2%ae-ea","provider":"Heat Pump Parts","version":"1.0","type":"link"}
