4 Soft Seat Design SOFT-SEAT Bi-directional seat with encapsulated elastomeric o-ring core for resiliency. Common seat materials include TFE, RTFE and UHMWPE. DISC 360° uninterrupted spherical edge for sealing. Profile is designed for maximum flow and equal percentage control. The Flowseal Soft Seat valve provides a bi-directional bubble tight shutoff (zero leakage) by the use of a patented seat. This unique seat design creates a self-energized seal in vacuum-tolow pressure applications. Under higher pressure conditions, the seat is also designed to permit, confine and direct movement of...

Disc open In Figure 1, the disc and seat are not engaged. In this position, the shoulders of the seat are forced against the cavity shoulders by the compression of the o-ring. The seat is recessed inside the seat cavity and acts as a gasket in the anchoring groove area. The seat cavity is sealed from exposure from the process fluid and protects the seat from abrasion and wear. The o-ring, which is completely encapsulated by the seat, is also isolated from exposure to the process fluid. Disc closed, Self-Energized Seal In Figure 2, the Flowseal disc and seat are engaged, and the process...

6 Fire Flow Design The Flowseal Fire-Flow™ high performance butterfly valve (HPBFV) is a fire-safe, soft seat quarter-turn valve. The Fire-Flow™ design incorporates a seat which function together to seal off pipeline flow. In normal operation, the soft seat provides a bi-directional "bubble tight" shutoff (zero leakage); in conformance to industry firesafe requirements. FIRE–FLOW SEAT Bi-directional soft seat design for zero-leakage in normal operation and a metal-to-metal seal after fire, meeting or exceeding industry "fire-safe" specifications. DISC SPACERS Disc is centered by use of...
