BODY
One-piece bodies are available in both wafer and full tapped lug designs. The standard longneck body provides full clearance for 2-inches of insulation with ANSI 150 pipe flanges.
STEMS
Heavy-duty, two-piece design allows for easy maintenance. Stems are secured by the use of retaining pins.
BEARINGS
Two bronze or Teflon®* bearings are standard on 2"-12". Sizes above 12" have full-length bearings on upper and lower stems.
Stem/Disc Attachment
Rectangular drive ensures proper disc connection. No pins or bolts are exposed to flow.
Seat
Elastomer, reinforced with phenolic backing ring, enables valve to be used on pressure or vacuum service. Seat can be field replaced. Grinnell's special double seal design eliminates the need for flange gaskets. Three stem seal O-rings are molded into the the seat liner to back up the primary stem seal.
DISC
Streamlined for maximum flow and minimum seat wear. Ease of maintenance due to the elimination of bolts, pins, etc., as disc to stem connectors.
Dead-End Service
A unique patented lip, integral to the body prevents the liner from moving downstream, eliminating seat and flange leakage. This feature allows lug valve to be used in uni-directional, dead-end service applications at full rated pressure without the use of downstream flange.
