Features Model Document

Molded-in resilient seat provides bubble-tight shutoff to 150 psi.
Temperature rating for standard EPDM seat: -40°F to 250°F (-40°C to 121°C).
Lugged body is drilled and tapped for isolation and removal of downstream piping at full rated pressure.
Round, polished disc and hub edge provides 360° concentric seating, minimum flow restriction, lower torques and longer seat life.
Upper and lower inboard bronze bearings ensure longer service life with low operating torques.
Thru-stem design provides high strength and positive disc control with standardized end connection for operator interchangeability.
Extended neck allows adequate clearance for flanges and insulation.
Bi-directional, select adjusting stem seat is suitable for vacuum and pressure while preventing external contamination of the stem area.
Heavy-duty corrosion resistant top bushing absorbs actuator side thrust.
Cast-in top plate is an integral part of the body and is standardized to allow direct mounting of actuators.
Each valve is factory tested to 110 percent of specified pressure rating.
Available in multiple configurations to match jobsite needs.
