708HT SERIES HIGH TEMPERATURE CONTROL VALVE

Fractional Flow Control Valve with Finned Bonnet for High Temperature Service

The cooling fin bonnet option is for the protection of the stem packing from elevated temperature associated with steam, hot water, and high temperature oil, gas, and liquid services. The finned bonnet cools the area around the packing, which permits the use of standard packing materials that otherwise would not be suitable for the service temperature conditions.

Features & Benefits:

• For steam, hot water, and high temperature, oil, gas and liquid services
• Provides cooling effect on bonnet, protecting the packing from higher than normal temperature conditions
• For precise control of higher temperature fractional flow services in pilot plants and low flow process applications

LowFlow control valves and regulators are often used in OEM, laboratory or pilot plant applications for critical control of gases, liquids or steam. Installations such as these frequently require valve trim changes and a multitude of CVs in order to meet varying flow requirements for a given application.
