AAP 4 in Cast Iron Gate Valve, Rising Stem, Table D | VCIGRS94D

This AAP rising stem cast iron gate valve has a cast iron body, bonnet and wedge and flanges to AS 2129 Table D (manufacturer-stated). It is supplied in one size, 4 in (100 mm).

A wedge gate valve moves a wedge-shaped gate between two body seats using a spindle, so when it is fully open the fluid has a straight, uninterrupted passage with very little pressure drop. AAP says it is not recommended for flow regulation and should only be used fully open or fully closed. On a rising stem valve the stem lifts out of the valve as the handwheel opens it, so the stem position shows whether the valve is open or closed, and you need headroom above the valve. AAP describes the wedge as a solid wedge disc.

AAP gives a maximum temperature of 200 degrees C and a cold working pressure of 1,379 kPa (13.79 bar), with flanges to AS 2129 Table D (manufacturer-stated), and lists the valve for water, sewage and neutral liquid applications. The body, bonnet and wedge are cast iron with cast bronze seat and wedge face rings, a brass stem, Teflon packing and a graphite and steel body gasket.

Materials

Key specifications

Selecting the right option

Choose the size to match your Table D flanges, and check the hole count against your mating flange, because it differs between Table D and Table E. Allow headroom above the valve for the rising stem.
