Duco® DGL Series is a commercial-grade tee globe valve designed to achieve a perfect shut off or fluid throttle in the system even after years of use.
It is commonly installed to modulate the flow restriction near the boiler sensor, reducing the steam rate which prevents steam flashing.
The body is made of bronze which is high ductility (crack resistant) and corrosion resistant. Contains lead, not for use in water systems intended for human consumption.
