' • Extended neck allows adequate ' clearance for flanges and insulation. r • Bi-directional, self-adjusting stem seal, located in the upper journal, is suitable for vacuum and pressure while also preventing external contamination of the stem area. • Heavy-duty corrosion resistant top `. bushing, located in the upper journal, absorbs actuator side thrust. • Cast-in top plate is an integral part of the body and is standardized to allow direct mounting of all Tyco actuators. • Each valve is factory tested to 110 percent of specified pressure rating. General Application Technical Data Heating,ventilation, air conditioning and Size Range : 2-12-inch wafer and general industrial services. lug style Pressure Rating : 250 psi bi-directional shutoff. Lugged body style is rated for 250 psi bi-directional dead-end service with downstream piping removed.
