HGV250 Series - Hydrant Gate Valve 2.5" Hydrant Gate Valve QST, Aluminum Anodized Click on the PDF TAB above to review the Standard Canadian Thread Sizes and Steps on How to Measure Your Threads. USAGE Hydrant Gate Valves are ideal for use in hose testing, hydrants, stand pipes and pumps. The HGV250 Series and HGV250-DS-Y Series are excellent shut-off vales used on the 2 ½” outlet port of hydrants to control water hammer and reduce hydrant main damage. Both Series are supplied with Full Flow Waterways and just 11 easy turns to open and close. Maximum operating pressure 250 PSI. TERMINOLOGY Casting is a process where the metal is melted before going into a mold. The metal pours into the mold and solidifies as it cools. The control of the molten metal temperature is critical. Likewise, the quality of the metal being melted must be controlled so that no impurities get into the molten metal. Anodizing is an electronic process that converts the metal surface into a durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. MATERIAL HGV250 Series Body cast from 356-T6 grade aluminum construction supplied hard coat anodized for corrosion resistance. Stainless Steel Spindle. Stainless Steel Ball Bearings and Set Screw. Hard Coat Anodized Gate, Swivel and Male Threads. Supplied with 3 Spoke Hand-wheel. HGV250-DS-Y Series (Heavy Duty Yellow) Body cast from 356-T6 grade aluminum construction supplied hard coat anodized with powder coat Vis Yellow body for corrosion resistance. Stainless Steel Spindle. Stainless Steel Ball Bearings and Set Screw. Hard Coat Anodized Gate, Swivel and Male Threads. Supplied with 3 Spoke Hand-wheel. Dual Seals on each side of Gate for seal proof shut off. NPSH – National Pipe Straight Hose. NPSH is sometimes referred to as “IPT” or Iron Pipe Thread. NPSH threads are straight threads and require a gasket for sealing between mating threads. NPT – National Pipe Tapered. This thread is most commonly found in pluming applications. NPT is a tapered thread and the seal between mating threads is made by squeezing the threads together. Therefore, no gasket is required. NPT and NPSH threads are similar in diameter and threads per inch. OPERATING PRESSURE HGV Series and HGV-DS-Y Series operating pressure is specified at 250 PSI. GASKETS High quality swivel gaskets are lathe cut ozone free EPDM.
