Angle valve

ISO 10628-2 (group 21, valves) / PIP PIC001

Drawn as

Two triangles at right angles: one pointing in from the side (inlet) and one pointing up from below (outlet), tips meeting, with a stem and handwheel on top.

Meaning

Globe-type valve whose outlet is at 90° to the inlet. Common for drains, chokes and blowdown. A spring on top makes it a relief valve, not an angle valve.

Variants

A dot at the tips makes it an angle globe valve
With an actuator it is an angle control valve
With a spring or a pilot box it is a PSV (see relief)
