Brand Fouress Ss Butterfly Valve, Media Water, Operation Type By Lever

Fouress #300 rating high performance butterfly-shaped valves well proven, Are reliable design provides bi, Directional shut, Off. 4s, V30 valves come equipped with a groove/step on the seat to be held in position between seatring and the body under throttled condition, When the valve disc is the high, Crack open velocity cannot pull the seat. Hence seat will not get damaged as a result of elevated velocity during control duty. Seal back, Up ring will prevent any undue outward motion of the teflon seat. The seat has been crafted to move slightly in the path of flow this allows the pressure entry to the back of the seat, Thus making the seat progressively tighter as the pressure increases. During reverse flow, Any deflection of the disc would tend to minimize the tightness but the pressure behind the seat compensates to preserve the seat tightness. Large area of seat contact this ensures increased tightness and shut, Off potential. Seat ring designed to move in the direction of flow this allows pressure access in the back of thus making, The seat the seal progressively tighter as the pressure increases. During reverse flow, Any deflection of the disc would tend to reduce the tightness but the pressure behind the seat compensates to maintain the seatringspecial features 4s, V30 valves could can serve as both on/off and control duty. Fully rated for 300#, May be utilized as much as 50 bar pressure. As per design standard ms, Sp68. Reliable design proved by cycle test.
