Enviro-Loc EVR Balance Fuel Hose from VST has a patented, variable design venturi that allows maximum flow rate with superior performance. Your customers will find it easier to use because Enviro-Loc hose is lighter and has more flexibility than any old-style vacuum assist hose. The VST EVR Balance hose design has no vapor tubing to stretch or kink, which can block the vapor path and can trigger a system alarm.

The VST Coaxial Balance Hose built-in permanent double swivels offer superior handling and less flex stressing on the hose which translates into longer service life.

All assemblies are UL listed.

Venturi is a device that creates a vacuum in a fuel line by constricting the fuel flow. The suction is used to extract condensation and excess fuel from the vapor line by means of pick up tubing.

VST's Ventrui flow sensor opens and closes venturi with changes in line pressure. This unique design provides the industries highest flow rates, 15% to 30%, higher than competitive designs. All fixed Venturi designs must exceed a minimum flow rate before they will function. VST's variable design compensates for low flow applications, thereby exceeding the CARB requirements for all flow rates. VST's VDV is the only Venturi hose to meet CARB's requirements for low flow evacuation of 50 ml at 5 GPM flow rate. The combined advantages of the VDV's higher flow rate and improved evacuation provide for significantly increased dispenser efficiency in balance systems.

Designed for Assist type systems where maximum flow rate and efficiency are required. Light-weight and flexible construction provides the most user friendly system available with up to 40% improved flow rates. Factory built-in value added products are integral parts to the hose and eliminate the need for secondary connections.

VST Assist Hose is also available in Healy style.

Customer benefits: Light weight assembly, offers maximum kink resistance, easy to handle, and reduces user exposue to gasline vapors.

All assemblies are UL listed.

• Inner Hose - Special formulated nitrile tube material offers superior chemical resistance. It will not stiffen, harden or flex crack when exposed to most know grades of gasoline. Superior resistance to wet dry applications that are normal in balance systems.

• Reinforcement - High tensile strength wire braid construction provides maximum coupling retention.

• Retaining Clip - Special "spider" design simplifies change over as no tools are required to replace the outer hose.

• Outer Hose - Resistant to all grades of gasoline, including oxygenated fuels containing MTBE and Ethanol.
