The Carmo 03‑374 Pressure Relief Valve is a durable, low‑profile ABS component engineered to deliver safe and reliable pressure control in inflatable products and technical textile applications. Designed to open automatically at a set pressure threshold, it protects structures against over‑inflation, temperature‑related expansion and unexpected pressure spikes—making it a trusted choice for buoys, rafts, maritime equipment, ballast systems and other inflatable assemblies exposed to changing environmental conditions.
As part of Carmo’s modular valve system, the 03‑374 valve fits directly into the standard 03‑601 HF/ultrasonic weldable threaded flange, enabling quick, secure installation. The system uses a G 3/4" threaded interface, ensuring strong compatibility with Carmo’s full range of modular components, including inflation valves and vacuum valves, to support versatile multi‑valve configurations.
Manufactured in Denmark using high‑precision injection moulding, this valve offers excellent dimensional accuracy, long‑term durability and consistent performance. Carmo’s production approach prioritises sustainability, ensuring high‑quality materials are used while minimising environmental impact.
When paired with the compatible weldable flange, the 03‑374 valve is suitable for HF welding to PVC and PUR‑based materials, providing dependable bonding and long‑lasting functionality in demanding marine, industrial and environmental applications.
Whether you are building inflatables, buoyancy systems or flexible tank solutions, the Carmo 03‑374 Pressure Relief Valve delivers a proven, industry‑standard level of safety, stability and performance.
This listing is for customers looking full box quantities, and offers exceptional value for manufacturers, OEMs and high‑volume production environments. By purchasing the full box quantity of 500 units, you benefit from Carmo’s best‑value bulk pricing, making this the most cost‑effective option for continuous production, inventory planning or large‑scale manufacturing projects.
