API609 Fire Safe Double Seated Fire Safe High Performance Industrial Valves

API609 Fire Safe Double Seated Fire Safe High Performance Industrial Valves

Double Eccentric High Performance Butterfly Valve, with patented seat, provides bi-directional seal, Metal Seal and API609 Fire-safe seal design.

Soft seated: Bi-directional seat with encapsulated elastomeric o-ring for resiliency. Common sea materials include PTFE, RPTFE and UHMWPE.

Metal Seated: TEKO metal seat with metal back-up ring to accomplished by the line contact between a spherical surface and conical surface.

Fire safe seat: Double seat design, bi-directional soft sea design for zero-leakage in normal operation and a metal-to-metal seal after fire, meeting or exceeding industry ”fire-safe” requirements.
