Our stainless steel vent plug is designed to provide reliable pressure and vacuum relief for tanks, vessels and piping systems. Constructed from high-quality stainless steel for superior corrosion resistance and durability, it ensures safe and efficient โbreathingโ of the systemโletting air in or out as required to maintain pressure equilibrium, prevent tank deformation and protect equipment integrity.
Key Features
1๏ผBody material: 304 or 316L stainless steel (depending on model) offering excellent resistance to harsh chemical and environmental conditions.
2๏ผPressure/Vacuum relief: Automatically opens to vent excess positive pressure, and/or draws in air when vacuum occurs โ thereby maintaining near atmospheric internal pressure.
3๏ผWide operating temperature range and durable sealing materials: Seals made of PTFE, EPDM or Viton are available depending on application. 4๏ผVarious connection sizes and types: Threaded, tri-clamp, flange or sanitary connections to suit different tank or vessel configurations.
5๏ผHygienic / sterile versions available: For food, beverage or pharmaceutical applications, with polished internal surfaces and sanitary fittings.
6๏ผCompact and reliable design: Minimal maintenance, simple installation (typically mounted at top of tank/vessel) and stable performance over time.
Technical Specifications (typical)
1๏ผMaterials: 304 SS or 316L SS for body; sealing components PTFE/Viton/EPDM.
2๏ผPressure relief range: e.g., +0.9 PSI for vacuum break, +1 PSI for positive pressure (factory pre-set for hygienic version)
3๏ผTemperature range: approx. โ10 ยฐC to +140 ยฐC (14 ยฐF to 285 ยฐF) for hygienic model.
4๏ผConnection sizes: 1.5โณโ3โณ OD in hygienic version; other threaded/flanged sizes available.
5๏ผFinish: Internal / external mirror polish (for sanitary types) with Ra < 0.6 ยตm for ID.
It is widely used in mechanical automation, new energy vehicles, wind power energy storage, electronic communications, marine and aviation, nuclear power plants, and various other scenarios
Excellent Waterproof Sealing
The nickel-plated brass ventilation valve resists corrosion and high temperatures. Its hydrophobic, breathable membrane ensures breathability and waterproofing, blocking liquids and dust while balancing pressure differences to prevent seal failure.
Protection Safe and Reliable
It can be dust-proof, salt-proof, acid-alkaline, alcohol-grease and general solvent, suitable for outdoor harsh environments Plug and play, convenient and fast.
