BULLETIN 10.00-1 JANUARY 2009 VALVE SELECTION GUIDE Plug Valves Eccentric Plug Valves (PEC) 100% Port Eccentric Design Features: Eccentric action and resilient plug Plug Valves (PEF) facings assure lasting dead-tight shutoff. An inherent Design Features: Port is 100% of standard pipe linear flow characteristic is ideal for throttling applica- area, including straight through body design with tions. Heavy-duty stainless steel bearings, choice of flushing port to maximize flow capacity and reduce resilient plug facings, welded-in corrosion resistant headloss. Rectangular port design provides wide nickel seat, adjustable packing and a variety of end tolerance seating geometry for lasting superior styles are available. Capable of handling clean and shutoff. Standard features include corrosion dirty liquids and gases, sludges and slurries. resistant bearings, welded nickel seat, grit excluders, adjustable packing and a choice of Size Range: .5–72 (15–1800mm) resilient plug facings.
