Safety valve Afriso 3/4" 6 bar model 42234, pressure relief valve for heating and plumbing

Afriso safety valve model 42234 is a 3/4" pressure relief valve designed for heating and plumbing systems that require a 6 bar set opening pressure. The valve protects boilers, water heaters and connected piping by opening at the set pressure and discharging excess fluid to prevent overpressure. Constructed for use in residential and light commercial installations, this pressure relief valve is compatible with conventional hot water and central heating systems where a reliable 6 bar safety device is required.

Advantages

The Afriso 3/4" 6 bar safety valve provides precise pressure relief at the specified set point and is designed for straightforward installation on compatible system ports. Its mechanical operation requires no external power and it is made to withstand repeated openings and closings under normal service conditions. The valve’s size and connection type make it suitable for a wide range of domestic and small commercial heating and plumbing applications where a 6 bar relief capacity is specified.
