Unidirectional Explosion-Proof Valve

PUW is a leading Explosion-Proof Valve Manufacturer specializing in high-precision safety solutions for new energy vehicles (NEVs) and battery systems. Our Unidirectional Explosion-Proof Valves are engineered to maintain pressure balance and provide rapid relief in non-vacuum sealed cavities of battery packs, ensuring both performance and safety in harsh environments.

The PD12ALM20*1.5-15 model is made from high-grade aluminum with anti-oxidation coating, offering excellent corrosion resistance and a protection rating of up to IP68. Designed with a dual-channel system for ventilation and pressure release, our valves efficiently manage gas while providing precise and repeatable activation under predefined pressure thresholds.

Product Description & Application Value

A Unidirectional Explosion-Proof Valve, also known as a One-Way Explosion-Proof Valve or Explosion-Proof Vent Valve, is critical for controlling overpressure events in lithium battery packs, EV battery modules, and industrial energy storage systems. By allowing controlled venting in a single direction, these valves prevent structural damage, reverse flow, and potential explosions.

Our EV Battery Explosion-Proof Valve solutions are widely applied in:

• Battery Pack Explosion-Proof Valve systems for NEVs

• Pressure Relief Valve for Battery enclosures

• Gas Release Valve for EV Batteries

• Industrial safety systems with high-pressure risk

The valves are also compatible with dust collectors, chemical storage tanks, and pharmaceutical vessels, ensuring personnel and equipment protection in various industrial scenarios.

FAQ

1. What is a Unidirectional Explosion-Proof Valve?
It is a One-Way Explosion-Proof Valve that allows pressure to vent in a single direction, protecting personnel and equipment during explosive events in batteries, dust collectors, or chemical systems.

2. How does it differ from a bidirectional valve?
Unlike bidirectional valves, our unidirectional valves prevent reverse flow and secondary explosions, making them safer for enclosed systems.

3. What materials are used?
Aluminum alloy, stainless steel, and explosion-proof composites. Optional ePTFE membranes provide waterproof and breathable capabilities.

4. What is the standard opening pressure?
Customizable from 0.05 bar to 1.5 bar, depending on system requirements.

5. Where is it commonly used?
Battery pack enclosures, EV/NEV systems, dust explosion protection, chemical storage, pharmaceutical vessels, and industrial high-pressure systems.

6. Can I request a custom valve design?
Yes. PUW supports full customization including shape, size, pressure rating, material, installation method, and flame arrestors.

7. Are your valves compliant with international safety standards?
Yes. All valves comply with ATEX, EN14491, EN14994, and NFPA68 standards. Third-party testing reports are available.
