The BLD8887 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 BLD8887 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 BLD8887 valves. It is used to equalize pressure or vacuum differentials in order to open the container.

1.00-20 UNEF Thread Double Differential Relief Valve.

The BLD9146 Breather Valve fills the need for a low cost, but higher flow valve than the BLD8887 Breather Valve. The valve can be used on transit cases and similar applications up to 33 cubic feet in volume. It has a flow rate of 4.0 scfm and is available in settings from 0.5 psi to 5.0 psi.

The valve is lightweight, rugged, tamper-proof and requires no field maintenance. Corrosion-resistant materials are used throughout. The valve seal is made of silicone rubber. A recessed manual release push button is standard on all Breather Valves Versions. It is used to equalize residual pressure or vacuum differentials in order to open the container.

Please contact us for more information.

0.75 x 16 UNF Double Differential Relief Valve (With Weather Shield)

The BLD9314 Breather Valve, a weather shielded version of Brownell's time tested BLD8777 Breather Valve, was designed to meet the need for a weather shielded, 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.

The BLD9314 Breather Valve 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.

The conversion coated housing allows for use of a conductive o-ring for minimal RFI shielding. For higher energy RFI shielding, Brownell's standard style RFI nuts are available.

BLD9132/01
¾" Thread Double Differential Relief Valve

The BLD9132 Breather Valve has separate and distinct settings for both pressure and vacuum relief. It has a flow rate that ranges from 1.5 to 4.0 scfm at 1.5 psi above the valve reseal setting, making it suitable for containers and similar applications up to 33 cubic feet in volume. Standard settings are available from 0.25 psid to 3.0 psid reseal pressure. The lower the setting, the higher the flow rate.

The BLD9132 Breather Valve is tamper-proof and requires no field maintenance. Corrosion-resistant materials are used throughout. The valve seal is made of silicone rubber. The spherical valve seat is Teflon coated for easy "break-away" action even after prolonged storage. The manual release push button is used to equalize the pressure or vacuum differentials in order to make opening the container easier. The button is recessed in the cover to protect it from damage and eliminate the possibility that an adjacent container might press the button and inadvertently cause the valve to remain open. A unique feature of the push button is a light duty spring under the cover, separating the button from the vacuum stem, which must be overcome before the button opens the valve.

 

The BLD9132 valve is offered in two types: “Cracking” and “Reseal”. Cracking valves are rated by cracking pressure (the pressure at which the valve has opened enough to flow 1 cubic centimeter per minute) and the flow rate at 1.5 psi above the cracking pressure. Reseal valves are rated by reseal pressure (the pressure by which the valve is guaranteed to close after it has cracked open) and the flow rate at 1.5 psi above the reseal pressure.

Gasket, washer and hex nut are provided with each valve. A weldable nut is available for use as a threaded boss, or the valve may be used with our Mounting Flanges. RFI/EMI shielding is also available.
