The L1200 series offers Groth’s special “cushioned air” seating. Superior performing fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture. The L1200 series has a self draining housing body and drip rings to protect seating surfaces from condensate and freezing. This design also avoids dangerous pressure or vacuum buildup due to binding or clogging of the valve. To insure the proper alignment of seating surfaces, there is peripheral guiding and a center stabilizing system.
• Buna-N, Fluoropolymer, FKM and other seating diaphragms
