Our two-way pressure valves, or breather valves, have proprietary design characteristics that ensure the valve opens, or “cracks”, at the desired pressure and provide significant flow rate at lower differential pressures.
One-way pressure and vacuum relief valves can be used if it is unnecessary or undesirable to relieve pressure in both directions.
We offer a growing collection of accessories to help engineers meet mil-standard requirements including humidity indicators, observation windows, record holders, and access ports.
These older designs are still available for purchase for existing systems but we generally don’t recommended them for new projects. Refer to our other product categories for current offerings.
