SHEARSEAL KNIFEGATE VALVE
Shearseal Design
Most knife gate valve manufacturers describe their valve as rugged and dependable. In the Shearseal Valve, these qualities are not idle claims. The product has been designed and built in Australia without any cost cutting measures adopted by many mass producers
Compare a Shearseal Knife Gate Valve with any of its competitors. The Shearseal valve is stronger. The additional strength comes from built in reserves where it is most need in full bodied castings, reinforced gland and stuffing box sections extra thickness in the stainless steel gate, heavy duty stainless stem, and bronze drive nut, large diameter hand wheel and ball thrust races in all sizes. Four gland bolts – not two. O-ring sealing standard at no extra cost.
Every component used in the construction of a Shearseal Knife Gate Valve is built to last, as you would expect in any valve having easily replaceable seat rubber for maximum service life. Seat pressure rating 1034 kpa (689 kpa for valves 200mm and bigger up to 750mm)
The superior design and construction of valves follows three decades of development of the o-ring seating principle. Rubber seated knife gates are used around the world in traditional knife gate valve markets, with an increasing number of new users, who have found in this design all the advantages of pocket less knife gate construction without compromising fluid tightness, directionality, bore dimensions and finish.
All valves can be flange drilled either to wafer or lugged/tapped to any specification required for the job such as Table C, D, E, F and H, ANSI 150 and 300, DIN 10, PN10 and 16 as well as S.A.B.S 1123 to name a few. If you require anything else or require special needs it can be accommodated.
