Explosion-proof Moisture Barrier Vent

The Explosion-Proof Moisture Barrier Vent, model PB10ALM42*1.5-10P-8T, is engineered to deliver an optimal combination of explosion protection and moisture prevention, making it an essential component in industries where both flammable gases and high humidity pose significant risks. This advanced Waterproof, breathable, and explosion-proof valve is specially designed to allow safe and controlled pressure release while preventing the ingress of moisture, dust, and contaminants.

Technical Specifications

Key Features and Benefits

Explosion-Proof and Moisture Barrier Functionality

The valve's explosion-proof design ensures it can safely vent gases without igniting volatile atmospheres, while the moisture barrier feature effectively blocks water vapor and liquid from entering sensitive enclosures. This dual protection makes it ideal for use in hazardous chemical processing, oil and gas facilities, and mining operations—environments that demand strict safety and environmental controls.

High-Performance Airflow and Pressure Regulation

With an air intake permeability of ≥ 9 ML/min at 1.5 kPa and gas output exceeding 50 ML/min, the valve facilitates effective ventilation and pressure equalization. Under a slightly higher pressure of 2.5 kPa, the air intake can reach ≥ 15 ML/min, with gas output over 600 ML/min, ensuring rapid and safe pressure release. The valve opens at a pressure range of 7 to 13 kPa, preventing enclosure deformation or failure caused by pressure build-up.

Robust IP68 / 6K9K Waterproof and Dustproof Protection

The IP68 / 6K9K ingress protection rating guarantees that the valve remains impervious to dust ingress and powerful water jets or immersion. This ensures long-term reliable operation in outdoor enclosures, marine environments, and other harsh conditions where moisture can cause equipment failure or corrosion.

Durable Construction with Aluminum Alloy Body

The valve body is crafted from high-quality aluminum alloy, combining strength, corrosion resistance, and light weight. The exterior flange type installation (moisture barrier type) and threaded mounting design provide secure, leak-proof attachment to electrical and control enclosures.

Applications

The Explosion-Proof Moisture Barrier Vent is widely applied in environments requiring strict explosion-proof measures alongside moisture protection, including but not limited to:

• Mining equipment and control cabinets

• Oil and gas industry enclosures

• Hazardous chemical processing plants

• Outdoor electrical control boxes and junction boxes

• Battery storage enclosures and charging stations

• Marine communication and navigation equipment housings

By incorporating this valve into your equipment, you enhance safety and durability by balancing pressure, preventing moisture ingress, and reducing explosion risk.
