• Quality

  ISO 9001 registered. ENARDO products are world-renown for their innovative design, efficiency and long life. In a word -- quality.

• Price

  Now ENARDO quality is available at a value price. Our new Series 450 (pipe-away) and 550 (vent-to-atmosphere) pressure vacuum relief valves deliver the features you need at the price you want.




• Performance

  Low, up-front expense is just the beginning.

• Ease and speed of maintenance keep costs down.
• High flow maximizes cost-effectiveness.
• Tight seal reduces emissions and product loss

• Low Maintenance

  Because the pallet and seat may be replaced without dismounting the valve or using special tools, production suffers less down time. Fewer man hours are spent on repair. Spare parts inventory is reduced to sealing surfaces only instead of whole valve assemblies. Similar valves on the market need to be removed from the line and, if repairable at all, re-machined. ENARDO valves deliver.

• Replaceable seats.
• Stainless steel pallet
• FEP Teflon® pallet seals

• Corrosion Resistance and Durability

  ENARDO's valves are at home in the harshest environments including on and off shore petrochemical production, processing and storage; food processing; and pharmaceutical production. Pallet seals are durable FEP Teflon® for long life and durability. Valve bodies are available in carbon steel, stainless steel, or aluminum, as service requires. A coating of Amershield™ aliphatic polyurethane is standard for all external surfaces. Amershield™ provides excellent chemical, impact and abrasion resistance.

  Great valves. Great value. ENARDO valves are available when and where you need them. And, if you have system design questions, the engineers at ENARDO provides solutions when and where you need our expertise.
