BRA.Y6.623 - check valves threaded stainless steel

This category includes threaded stainless steel check valves from the BRA.Y6.623 series. These valves are designed for use in heating, ventilation, and air conditioning (HVAC) systems, as well as water supply lines, pumping stations, oil and hydrocarbon systems, chemical and food industries. They operate at temperatures ranging from -20°C to +180°C and can handle pressures up to 40 bar. Available in sizes from 1/4" to 2", they feature full female threads according to ISO 228-1 standards.

The valves are constructed with a body and disc made from A351 CF8M stainless steel, springs from AISI 316, and PTFE seals. They are suitable for water containing up to 50% glycol and require a minimum opening pressure of 0.15 bar. They are not recommended for steam applications. They meet drinking water regulations under Czech Ordinance No. 409/2005 Coll.

How to choose

• Select the correct nominal size (from 1/4" to 2") based on the pipe dimensions and flow requirements of your system.
• Ensure the valve has female ISO 228-1 threads matching the fitting requirements of your installation.
• Confirm compatibility with the working medium—these valves are suitable for water, glycol mixtures, oils, hydrocarbons, and chemical environments but not for steam.
• Verify the operating temperature range (-20°C to +180°C) aligns with your system's conditions.
• Check the minimum opening pressure (0.15 bar) meets the needs of your application.
