For air, water, non-corrosive and non-viscous liquids
The GD-200/200H valves offer high capacity and
highly accurate control, with a large, cupped diaphragm for a long
stroke. Compact and rugged, the GD-200’s composition valve and bronze
metal seat mean high performance over a longer service life. Well suited
to non-viscous liquid pressure reduction, the valve is widely applied
in domestic water applications, construction equipment, irrigation,
tank-car loading, and industrial or commercial air conditioning.
Upstream variations do not affect the balanced pressure valve, and the
composition disc ensures tight shutoff. The turndown ratio is 10:1, and
sizes range from 2″ through 6″ (15–50 mm).
