The DH/D8887 Breather Valve was designed to meet the need for a low cost, two-way valve for use on transit cases and similar applications up to 4 cubic feet in volume. The valve has separate and distinct settings for both pressure and vacuum relief. It has a flow rate of 0.5 scfm at a pressure of 1.5 psi to 2.0 psi above the valve setting. Standard settings range from 0.5 psid to 3.0 psid reseal pressure, please contact us if this is not what you are looking for.
The DH/D8887 Breather Valve is tamper-proof and requires no field maintenance. Corrosion-resistant materials are used throughout. The valve seal is made of silicone rubber. Each valve comes complete with a nut and o-ring, and is intended for small cases that require a low profile valve. A manual release push button is standard on all DH/D8887 valves. It is used to equalize pressure or vacuum differentials in order to open the container.
