Ball Valve
Ball = trim component that varies the area of the flow within the valve body.
Ball seals = outside, on either side of the ball, to prevent leakage.
Flow characterizer,or integral flow insert = provides ball valves with their equal
percentage flow characteristic.
Stem and packing = are at the top connects the valve to the actuator
and prevents leakage around the stem.
Mounting bracket = where the actuator gets mounted to the valves.
Valve components
Butterfly Valve
Valve body = contains the plate at the top, which is also used for mounting the
actuator. The most common type of butterfly valve is the lug type, which is
the valve type pictured.
Stem = connects the actuator to the valve.
Disc = component which makes contact around the resilient seat. The position of
the disc, controls the amount of flow, and closes into the rubber seat to provide
close off.
Seat = provides that surface for the plug to seal and stop flow.
Globe Valve
Bonnet = top of the globe valve which contains the packing and is where the
actuator attaches to the valve plug.
Stem guide = supports the stem
EPDM packing cartridge = prevents leakage around the stem.
Trim = refers to the material of the plug and the seat components.
Plug = varies the area of flow within the valve body, and determines the flow
characteristic of the valve.
Seat = provides a surface for the plug to seal and stop the flow.
