Drawing   3D Model

The BV2000 two-way pressure relief valve is a popular valve for medium to large containers and has been optimized to provide maximum air flow at a low differential pressure to protect from overpressurization. One valve provides enough air flow for an internal volume of 416 ft3. An aluminum shield is provided to prevent intrusion of water during spray-down as well as wind-driven sand, dust, and rain. To manually equalize container pressure, the valve can be opened by pressing the button in the center of the shield. The valve is installed using the included hex mounting nut.
The pressure and vacuum directions work independently from each other so any of the available pressure and vacuum settings can be combined to meet requirements.
Compliant with Navy drawing 6212863.

 

Description

Configurations

The first dash number after “BV2000” indicates the setting in the pressure direction. The second dash number indicates the setting in the vacuum direcion.
Any of the below pressure and vacuum settings can be combined. For example, if a 0.25 psi cracking pressure and a 1.25 psi cracking vacuum are desired, use part number BV2000-025-125.
