4.4.1.6 Function
The main components of the globe valves are the pressure-retaining parts, i.e. the
body (1) and the bonnet (7), and the functional unit.
The body (1) and the bonnet (7) are connected by studs (5), and the joint is sealed to
atmosphere by the gasket (26).
The functional unit consists of the valve disc (2), the stem (4) and the bellows (8). The
actuating unit is a handwheel (20) or actuator.
The stem (4) passage through the bonnet (7) is sealed off by the bellows (8). The
back-up gland packing (11) is tightened by means of two eyebolts (22) and nuts (23).
The bellows-type stem seal is maintenance-free.
The seating surfaces of the body seat and the valve disc (30) are made of stainless
materials. The handwheel (20) is mounted on the square or hexagon of the stem nut
(17) and secured with a threaded ring (18).
