Combined Indicators & Relief Valves

Combined Indicators & Relief Valves

Combined Indicators & Relief Valves are designed for installation in places with limited spaces, requiring one hole for fitting into equipment or container. A reversible indicator, the sensor paper will change from blue to pink when humidity increases, reverting to blue as humidity returns back to normal. Desiccant cartridges, also known as static desiccators, are additional units/optional tools which can fit most combined indicators & relief valves, adsorbing moisture entering the equipment during its use.

Humi Pak offers our Indicator and Relief Valve in 4 different models:

  • BLD9720/01-06 – ¾” Thread Humi-Valve

The ¾” Thread Humi-Valve features a humidity indicator and a two-way breather valve incorporated within the same housing, allowing users to save cost by eliminating the need for an additional hole in the case. The valve features separate and distinct settings for both pressure and vacuum relief. There is a separate path to the humidity indicator. The breather valve is lightweight, rugged, tamper-proof, and does not require the need for field maintenance.

The product also features corrosion-resistant material used throughout, and its valve is made of silicone rubber. Users can activate the unit with the manual release push button featured on all breather valves. This button equalises residual pressure or vacuum differentials to make the opening of the container easier. A gasket, washer, and hex nut are provided with the purchase of each valve.
