Direct acting DRV
The DRV is a fully balanced direct acting reducing valve suitable
for general service applications including for use on steam, air,
industrial gases and liquids and will operate at pressures
up to 40 bar inlet and temperatures up to 300°C. It is designed
to reduce from very high to very low pressures and is ideal for
higher capacities, where loads are fairly constant it will give very
consistent, reliable and accurate control even under the most
arduous working conditions, such as wet and dirty steam.
