Conval (Somers, CT) introduces the Clampseal Throttling Valves, ideal for severe service applications that require repeatable flow control and dependable shut-off. The valves are available in ½” through 4” sizes through ASME Class 4500. Standard forging materials include SA 105, SA 182-F22, SA 182-F91, SA 182-F92 and SA 182-F316. Features include the following:
- The venturi is an integral part of the removable seat. Both the seat and the stem assembly are easily changed in-line should a flow characteristic change be required or replacement necessary from excessive corrosion or erosion.
- The orifice is sized to keep fluid velocity across the seat below damaging levels. The exit orifice angle is designed to minimize downstream piping erosion and noise.
- The simple and effective pressure seal bonnet provides ready access for servicing with no welds to cut or seal rings or gaskets to replace. The body-to-bonnet joint integrity is maintained through countless thermal cycles.
- The durable single-piece stainless steel gland contributes to the longevity of the valve.
