Overpressure Blast Valve

The Overpressure Blast Valve Type A 3603 is a valve used to stop explosive blast waves from entering a bomb shelter as well as to regulate the air pressure in the shelter. The valve is tested and certified to the Israeli Standard 4570 by the Civil Defence Command and the Standards Institution of Israel.

The Overpressure Blast Valve Type A 3603 is designed to release air from the shelter while maintaining a constant overpressure and also to protect against explosive and implosive blast waves. The valve is normally closed. It is maintenance-free and withstands heat and corrosion. The springs are manufactured from special stainless steel and all steel parts are phosphate treated and finished with a powder coating.

Usage

• Has to be installed inside the shelter on a 14" flange according to BS 4504 - PN 6 or DIN 2501 - PN 6

• Should only be installed together with "Noah's Ark" equipment manufactured by Beth-El Industries to ensure maximum performance

Certifications:

• Tested and certified to IS 4570 by the Standards Institution of Israel

• Approved by the Civil Defence Command of Israel

• Quality Control according to ISO 9001

• Quality Assurance AQAP 120

Overpressure Blast Valve

The Overpressure Blast Valve Type A 7003 is a valve used to stop explosive blast waves from entering a bomb shelter as well as to regulate the air pressure in the shelter.

The Overpressure Blast Valve Type A 7003 is designed to release air from the shelter while maintaining a constant overpressure and also to protect against explosive and implosive blast waves. The valve is normally closed. It is maintenance-free and withstands heat and corrosion. The springs are manufactured from special stainless steel and all steel parts are phosphate treated and finished with a powder coating.

Usage

• Has to be installed inside the shelter on an 20" flange

• Should only be installed together with "Noah's Ark" equipment and accessories manufactured by Beth-El Industries to ensure maximum performance

Certifications:

• Quality Control according to ISO 9001

• Quality Assurance AQAP 120

Overpressure Valve

The Overpressure Valve Type Z 500 D is designed to regulate the differential pressure between the different areas inside the shelter. The valve is normally closed. It conforms to the Israeli, Singaporean and Swiss standards. The Valve is tested and certified by the Civil Defence Command and the Standards Institution of Israel.

The Overpressure Valve Type Z 500 D is maintenance - free, temperature and corrosion resistant. The differential pressure between rooms may be adjusted to the required value. The valve must be installed only inside the protected area.

Usage

• Has to be installed between the mainshelter and decontamination area/sanitary rooms.

• Has to be installed on an 8" flange according to BS 4504 - PN 6 or DIN 2501 - PN 6

• Should only be installed together with "Noah's Ark" equipment manufactured by Beth-El Industries to ensure maximum performance

Certifications:

• Tested and certified to IS 4570 by the Standards Institution of Israel

• Approved by the Civil Defence Command of Israel

• Quality Control according to ISO 9001

• Quality Assurance AQAP 120

Gas-tight Shut-off Valve

With achieved Excellency, the PPV Valves are a reliable solution to the requirement of gas tight shut off valves in Bomb Shelters. The vulcanized rubber lining, light weight body and long neck, all contribute to the manicured performance of the Gas-tight Shut-off Valve. The smooth disc without pins of screws and the intensive split shaft make operation smooth.

Usage

• Available in a variety of different size

• Should only be installed together with "Noah's Ark" equipment manufactured by Beth-El Industries to ensure maximum performance

Differential Pressure Gauge

The Differential Pressure Gauge Type DPG-A shows the differential pressure between two rooms. It is used in shelters to indicate the overpressure disparity between the shelter and the outside area, or the differential pressure between the different areas inside the shelter.

Selected for its high accuracy, the cost effective Differential Pressure Gauge Type DPG-A, is guaranteed to be accurate within 2% (of full scale) suiting precise needs. Low air pressure, positive, negative (vacuum) or differential, are quickly indicated on an analog display, using simple frictionless movement. It is designed to resist shock, vibration and overpressures. The Differential Pressure Gauge withstands a blast pressure of 40 bar at an impulse of 70 bar ms.

It has no manometer fluid, alleviating the problems of fluid evaporation, freezing, toxicity of leveling difficultise.

Tested and certified for compliance to the Israeli and Singaporean Standards.
