| ROOTS Ultraseal Gas Meter Valves Ultraseal 
    valves are permanently lubricated and bi-directional. They meet NPFA 
    standards and continue to maintain a bubble-tight seal after Qualification 
    testing to over 10,000 cycles. Torque values remain low even at subzero 
    temperatures. Locking plates are also available.  ROOTS Pipeline Strainers  These strainers are designed to protect meters and other precision 
    devices from the damaging effects of entrained system debris. A low pressure 
    drop is achieved through a large element area and venturi port design. The 
    debris bowl is tapped for cleaning.  ROOTS Gasket Strainers  Using a 20 mesh stainless steel screen, the Gasket Strainer helps protect 
    against potential damage to precision pipeline measurement and regulation 
    equipment caused by occasional introduction of weld slag, plastic pipe 
    shavings, or other debris.  Restricting Orifice Plates  Sized orifice plates provide low cost protection against meter overspeed. 
    The plates are designed to choke gas flow at 100% for meters rated over 300 
    PSIG. Plates are installed 2 to 4 pipe diameters downstream for maximum 
    effectiveness.  Companion Flange Assemblies  These include all the equipment necessary for mounting a meter in a 
    pipeline. The kit consists of flanges, coated flange bolts, and gaskets. |
