When the 3 bar threshold is exceeded, the internal spring-loaded gate automatically opens and discharges the excess volume of liquid into the atmosphere or a drain line, preventing the rupture of the tank, pipelines, and heat exchangers.\u003c\/p\u003e\n\n\u003ch3\u003eKey Advantages and Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHot-pressed brass body:\u003c\/strong\u003e Provides high mechanical strength, resistance to water hammer, temperature fluctuations, and zinc leaching during long-term contact with hot water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise spring calibration:\u003c\/strong\u003e A rigid factory setting for an opening pressure of 3.0 Bar guarantees reliable operation without delays or leaks during normal operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManual override rotary handle:\u003c\/strong\u003e The upper red ribbed plastic cap allows for manual forced opening of the valve for regular functional testing and cleaning the seat from scale.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEPDM elastomer seal:\u003c\/strong\u003e Ensures 100% tightness of the unit at operating pressure up to the moment of emergency discharge.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility and Application Area:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeating boilers:\u003c\/strong\u003e Wall-mounted and floor-standing gas, electric, and solid fuel boilers with a power of up to 50 kW (Bosch, Protherm, Vaillant, Viessmann, Baxi, Ferroli, Ariston, Danko, Mayak, Tenko, etc.).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater heating equipment:\u003c\/strong\u003e Indirect heating boilers, storage tanks (thermal accumulators), storage electric water heaters with a circuit operating pressure of up to 3 bar.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiping systems:\u003c\/strong\u003e Closed gravity and circulation systems for radiator heating and underfloor heating.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;

The flow direction must strictly correspond to the arrow on the brass body. Lead the discharge line from the side fitting into the sewer through a transparent funnel with an air gap to visually monitor leaks. Every 2–3 months, turn the red cap to flush the valve seat of hardness salts and prevent the disc from sticking.\u003c\/em\u003e\u003c\/p\u003e","brand":"Dostavka","offers":[{"title":"Default Title","offer_id":48092063695025,"sku":"19886","price":1364.0,"currency_code":"UAH","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0538\/8517\/3937\/files\/g1_3f46bbdb-9959-4d3f-a8ee-001e76487b8f.jpg?v=1792885837","url":"https:\/\/usefulrare.com\/products\/water-heater-safety-relief-valve-3-bar-34-internal-thread-brass","provider":"Dostavka","version":"1.0","type":"link"}
