Conval, a manufacturer of severe-service valves, has recently introduced a line of clampseal throttling valves. The valves are appropriate for use in applications that require accurate repeatable flow control and dependable shutoff.
The valve’s Venturi is a critical component of the removable seat. Both the seat and the stem assembly are easily changed inline in the event that modified flow characteristics are required, or replacement is necessary.
The orifice size is designed to keep fluid velocity across the seat under damaging levels. Meanwhile, the exit orifice angle is designed to reduce downstream piping erosion and noise. The 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 several thermal cycles. The durable, single-piece stainless-steel gland contributes to the longevity of the valve.
