Throttling valves provide dependable shutoff

By Chemical Engineering |

Clampseal throttling valves (photo) are well suited for severe-service applications that require repeatable flow control and shutoff. The valves are available in 0.5- through 4-in. sizes with a variety of standard forging materials. The valves’ venturi is an integral part of the removable seat. Both the seat and the stem assembly are easily changed inline in the event of a flow characteristic change or 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 pressure-seal bonnet provides service access with no need to cut welds or replace seal rings or gaskets. — Conval, Somers, Conn.
