GRV high temperature and high pressure globe valves includes WBY and GLT types, well resistant to water, steam, oil, hydrogen nitrate, acetic acid carbamide and other environments typical of gas & oil separtation plant, boiler and petrochemical fields. In particular, our WBY globe valves are widely applied to thermal and nuclear power station and petrochemical pipelines.

Most important components for both WBY and GLT valves are designed and manufactured in our own facilities, with complete tests and quality control to ensure their quality in full compliance with international standards but also to satisfy our customers with the easer service and long life performance.
