A-T Controls Series Power-SEAL P1 High Performance Butterfly Valves

Manual and automated POWER-SEAL Series P1 high performance butterfly valves come in three models: P1S: G2TFE soft seat design; P1F: G2TFE/316L SST fire-safe seat design; and P1M/P1H: 316L SST seat for Class V shutoff in high temperature applications. Soft and fire-safe seats offer bubble-tight, bidirectional shutoff to full ANSI/ASME Class 150 and 300 standards.

P1 Series replaces P Series high performance butterfly valves and features a new and improved seat material — G2TFE, which is comprised of 80% PTFE, 15% glass fiber and 5% molybdenum. Molybdenum adds lubricity and longevity to the seat.
