Should the actual operating pressure exceed the adjusted operating pressure, the valve then acts as a pressure regulator. The valve switches to pressure-free bypass operation when the spray gun shuts off and the spray pressure between gun and valve remains idle.\u003cbr\u003eThe valve can be operated together with several spray guns. It is also possible to connect several pumps to one common discharge line.\u003c\/font\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cfont face=\"Arial\"\u003eSafety Instructions\u003cbr\u003eObserve direction of flow. The bypass must under no circumstances be closed or fitted with any shut- off device.\u003cbr\u003eContinuous bypass operation without re- leasing the water can cause the liquid to heat up which in turn could damage the unit and endanger persons.\u003cbr\u003ePossible preventive measures:\u003cbr\u003e1.) Limit the bypass duration (max. temperature 70C); the duration is to be calculated by the operator and in conjunction with the operating conditions.\u003cbr\u003e2.) Use fittings (e.g. thermo valve on water inlet) to avoid heat increase.\u003c\/font\u003e\u003c\/p\u003e","brand":"SPECK Kolbenpumpfabrik","offers":[{"title":"100 \/ Standard Version","offer_id":46789799510173,"sku":"00.0639","price":173.75,"currency_code":"GBP","in_stock":true},{"title":"140 \/ Standard Version","offer_id":46789799542941,"sku":"00.0640","price":173.75,"currency_code":"GBP","in_stock":false},{"title":"100 \/ Handwheel Version","offer_id":46789799575709,"sku":"00.0804","price":199.38,"currency_code":"GBP","in_stock":false},{"title":"140 \/ Handwheel Version","offer_id":46789799608477,"sku":"00.0805","price":199.38,"currency_code":"GBP","in_stock":true},{"title":"200 \/ Standard Version","offer_id":46789799641245,"sku":"00.0817","price":193.13,"currency_code":"GBP","in_stock":true},{"title":"200 \/ Handwheel Version","offer_id":46789799674013,"sku":"00.0818","price":206.25,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/0025\/1037\/files\/ul221_2.png?v=1751539614"}],"url":"https:\/\/speck.co.uk\/collections\/unloader-valves-1.oembed","provider":"SPECK Pumps (UK) Ltd","version":"1.0","type":"link"}
