Description

Globe valves are designed for full fluid flow cut-off and equipped with shut-off device. These valves must be fully open or close during their operation. Globe valves are always single-seated.

We provide a full range of customer service including full warranty, 24/7 consultation and support, valuable insights into the ideal technical solutions in accordance with your requirements and expectations. At your desire we will be glad to supervise or execute the installation and commissioning process. Thanks to strict control over manufacturing process each equipment unit is inspected and recorded so the aftermarket support and spare parts delivery are notable for promptness and full interchangeability. To prolong the life-time of your equipment we are always ready to render on-site services from scheduled maintenance to troubleshooting, equipment inspection and emergency & repair works. All-time we keep our customers informed concerning possible improvements, up-to-date solutions and technical developments which can help to upgrade your equipment and enhance efficiency.
