The HK02ZA402-SL High Pressure Switch from Carrier is a reliable and robust component designed to protect hydronic heating systems from overpressure conditions. This switch is an essential safety device that provides peace of mind for homeowners or facility managers by ensuring the safe operation of the heating system.

The HK02ZA402-SL is a pneumatic switch, meaning it operates using compressed air or nitrogen. It is designed to activate when the system pressure reaches a predetermined level, typically between 40 and 80 psi (2.7 and 5.5 bar). Once the pressure threshold has been exceeded, the switch will open, releasing the air pressure and preventing further damage to the system.

The switch body is made of brass, which is known for its durability and resistance to corrosion. Brass is also an excellent conductor of heat, making it an ideal material for use in high-pressure applications. The switch features a stainless steel diaphragm, which is also corrosion-resistant and provides excellent flexibility, ensuring accurate pressure sensing.

The HK02ZA402-SL is easy to install and requires minimal maintenance. It comes with an adjustable factory set pressure of 50 psi (3.4 bar), but the pressure can be easily adjusted using the provided Allen wrench. The switch also features a clear pressure gauge, allowing users to monitor the system pressure at a glance.

The switch has a maximum operating temperature of 257 F (125 C), making it suitable for use in a wide range of heating applications. It is also compatible with a variety of hydronic heating systems, including hot water and steam systems, making it a versatile component for any heating application.

In summary, the Carrier HK02ZA402-SL High Pressure Switch is a reliable and robust safety device designed to protect hydronic heating systems from overpressure conditions. Its brass body and stainless steel diaphragm ensure durability and corrosion resistance, while its adjustable pressure setting and clear pressure gauge make it easy to use and monitor. With a maximum operating temperature of 257 F (125 C) and compatibility with a variety of heating systems, this switch is a versatile and essential component for any hydronic heating application.
