Protection of tanks against pressure and vacuum through pressure/vacuum relief valves
At EFSVALVES, we offer a specialized range of pressure/vacuum relief valves designed to protect tanks, vessels and pipelines against overpressure or vacuum conditions caused by temperature changes, emptying or rapid filling operations.
These valves ensure both safety and functionality in demanding applications such as food processing, pharmaceutical, chemical, laboratory and cosmetics industries—where reliable pressure control is critical to avoid structural damage or contamination.
Key features:
- Construction in AISI 316L stainless steel or Hastelloy, ensuring corrosion resistance in hygienic environments.
- Sizes available from ¼” to 4”, with BSP/NPT threaded, clamp, or EN/ASA flanged connections.
- Polished finish up to Ra 0.38 µm available on request—ideal for ultra-clean processes.
- PED/CE and ATEX compliant, suitable for European safety standards and explosive atmospheres.
These valves are an effective solution for protecting process integrity under varying pressure conditions and form part of our advanced safety offering for tanks and critical applications.
