Equate PV Valve 2.5″ EQUATE PV VALVE DESIGN FEATURES: Safer ratchet: Smaller, lighter, and easier to carry and well under NIOSH maximum 51 lbs used in lifting equations Longer life Higher quality Easier ratcheting Uses current tools (i.e. Jonny bar) and procedures Traceable (serialized) if required ERL’s Equate PV Valve is designed to automatically maintain safe design working pressure and vacuum levels within your tank barge. It remains vapor-tight until set point pressure or vacuum is reached, allowing vapor flow in or out at a rate sufficient to maintain safe levels within your tank barge.  Available in 2.5, 4, and 8 inch sizes Customizable pressure/vacuum curves Automatic operation Simple to use design Stainless steel construction 100% factory tested prior to shipment USCG approved design  Rebuild, COI re-certification and service available from ERL AUTOMATIC OPERATION Maintain safe design working pressure and vacuum levels automatically within your tank barge. It remains vapor-tight until set point pressure or vacuum overcomes the force of each respective set point spring, allowing vapor to flow out or air to flow in at a rate sufficient to maintain safe levels within your tank barge.  SIMPLE DESIGN Having very few parts, the Equate PV valve operates with two springs: one to determine the pressure set opening point and the second to determine the vacuum set opening point. A manual test handle allows tankermen to check the pressure ands vacuum sides of the valve. Weather covers easily remove to allow complete valve inspection in minutes. Easy to replace elastomer seals ensure vapor tightness.  100% STAINLESS STEEL & FACTORY TESTED All components are 300 series stainless steel for extended service life and reduce the need for maintenance. Every Equate PV Valve is 100% factory tested at our state-of-the-art testing facility prior to shipment and is USCG approved.   ADDITIONAL INFORMATION 2.5 inch Equate PV Valve • 35% lighter (34lbs vs 52lbs) • Smaller length (36” vs 51”); Same travel • Corrosion -protected components (nickelplated steel and anodized aluminum) • Fully sealed, permanently greased mechanism •  Made in the USA • Same operation: ACME rod with pelican hook • More ratchet teeth (60 vs 12) • Maximum work load of 35,000 lbs 4 inch Equate PV Valve • Safer ratchet: Smaller, lighter, and easier to carry and well under NIOSH maximum 51 lbs used in lifting equations • Longer life • Higher quality • Easier ratcheting • Uses current tools (i.e. Jonny bar) and procedures • Traceable (serialized) if required 8 inch Equate PV Valve • Safer ratchet: Smaller, lighter, and easier to carry and well under NIOSH maximum 51 lbs used in lifting equations • Longer life • Higher quality • Easier ratcheting • Uses current tools (i.e. Jonny bar) and procedures • Traceable (serialized) if required Talk to Our Sales Team CONTACT US RECOMMENDED PRODUCTS Lightweight Ratchet See Product Deck Stands See Product Pressure/Vacuum VibraGauge See Product Load More
