Actuated Plug Valves


Conforms to AWWA C504 wall thickness, the valve body casting is in ASTM A126 CL B cast iron using high pressure molding techniques. Alternative ends of flanged, grooved or mechanical joint ends are available. Flange diameter, thickness and drilling conform to ANSI B16.1 Class 125 or 250. Grooved ends meet AWWA C-606 for ductile or steel pipe. Mechanical joints to AWWA C111 (ANSI A21.11).


The valve incorporates as standard, on 3" and larger, a 1/8" thick welded 99% nickel seat for corrosion and erosion resistance specifically profiled for low torque and extended seat life.​



Supported on integral trunnions, the plug is totally encapsulated with an elastomer that is molded on 2-1/2" – 48" and vulcanized on 54" and larger to the casting providing tight shut off even under vacuum conditions. High integrity corrosion-free sealing is achieved by a variety of abrasion resistant elastomers which protect the plug right up to the trunnions. When assembled, the light compression of the elastomers onto PTFE thrust washers, prevents entry of abrasive materials into the bearings.
