Combined Relief Valves & Humidity Indicator
Combined Humidity and Relief Valves protect both humidity and pressure build-up with only one attachment.
Ideal when space is limited, combining a Humidity Indicator and Relief Valve together will only require one hole to be fitted to equipment or containers. While incorporating a humidity indicator and two-way breather valve within the same housing, this unit has separate and distinct settings for both pressure and vacuum relief.
Designed for mounting in moisture-sensitive electronic equipment or any other humidity controlled enclosure, it monitors and detects changes in space’s humidity. As the humidity increases, the sensor paper changes from blue to pink in colour, and as the humidity decreases, it reverts to blue.
Static desiccators can be fitted with a desiccant cartridge to adsorb and remove any moisture entering the equipment during its use. There are two models of combined relief valves and indicators – M24 Thread Pressure Relief & Humidity Indicator Unit and ¾” Thread Humi-Valve.
M24 Thread Pressure Relief & Humidity Indicator Unit
Apart from relieving pressure and monitoring humidity, a desiccator can be fitted on the rear of the unit using the internal thread for R.F screening continuity, allowing the unit to perform three functions in one product.
¾” Thread Humi-Valve.
This lightweight, rugged, tamper-proof breather valve contains a separate path to the humidity indicator. There is no need for field maintenance as the valve seal is made of silicone rubber, and corrosion-resistant materials are used throughout the valve. The manual release push button on the valve equalizes residual pressure or vacuum differentials, allowing containers to be opened easily.
Each valve comes with a gasket, washer, and hex nut.
