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...

BODY ANSI B16.34 design in either wafer or lug configuration. BLOW OUT PROOF SHAFT Solid shaft provides alignment and rigid support for disc. KEY Square key valve-to-operator connection provides an externally controlled failure point upon over-torquing. GLAND FLANGE Applies load against packing gland to prevent external leakage. Fully adjustable. PACKING GLAND Separate part from gland flange, preventing uneven load distribution against packing. PACKING Chevron design TFE prevents external leakage out valve neck to full ANSI hydrostatic shell test pressures (150% of C.W.P.). BEARINGS Both...

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...

BODY ANSI B16.34 design in either wafer or lug configuration. BLOW OUT PROOF SHAFT Solid shaft provides alignment and rigid support for disc. KEY Square key valve-to-operator connection provides an externally controlled failure point upon over-torquing. GLAND FLANGE Applies load against packing gland to prevent external leakage. Fully adjustable. PACKING GLAND Separate part from gland flange, preventing uneven load distribution against packing. PACKING Standard material is graphite. BEARINGS Both above and below the disc, bearings are of composite design: PTFE bonded to epoxy-glass filament...

In this position, the metal seat acts to keep the soft seat inside the seat cavity while the soft seat shoulders seal the cavity from exposure to the process fluid. (The o-ring is under tension and imparts a load against the soft seat.) The soft seat is protected from abrasion and wear...
