About this file
This document is a Brand Name or Equal Specification for a motor-operated plug valve assembly required for delivery to 7794 Folsom Dam Road, Folsom, CA 95630, Attn: Janell Vincent, on an F.O.B. Destination basis.
The specification calls for a ten-inch Nordstrum Dynamic Plug Valve Assembly (or equivalent) consisting of three integrated components: a 10" Nordstrum 1949 Plug Valve, a Limitorque MXB Series Electric Actuator, and a Limitorque WG35 Gear Box. The valve body must be ASME B16.34 Class 150 iron in Figure 1949 Short Pattern with a 10-inch nominal pipe size and a 13.00-inch face-to-face flanged dimension. The valve plug shall be a quarter-turn metal tapered design with a coated, low-friction surface and self-protecting metal seating. It must include an integral sealant system with a replaceable drop-tight sealant injection fitting and internal configuration that maintains pressure equalization while protecting the balancing system from foreign material. The gear box shall have a 52:1 ratio (or as appropriate for the connected actuator), adjustable quarter-turn travel, self-locking bronze worm gear with steel worm shaft, FA16 iron housing, and position indication on the housing cover. The electric actuator must be multi-turn, 3-phase, 60 Hertz, 480 VAC. The assembly shall be fully assembled and cycle tested at the factory. The contractor is responsible for protecting all parts from corrosion, deformation, and damage during storage, handling, and delivery, with any transit damage to be replaced at the contractor's expense.
