Product Range
Thermal Relief Valve
The Flow-Tek FT-100 (Screwed End) and FT-110 (Flanged End) models are specifically developed for critical service environments such as pharmaceutical manufacturing, food and beverage processing, nuclear installations, chemical reactors, pressure vessels, and pipeline systems.
The valve is particularly suited for high-pressure triplex plunger pump applications, where it safeguards pumps and associated pipelines from excessive pressure buildup.It is also commonly installed in air eliminator systems at petroleum product loading terminals, ensuring reliable pressure control and operational safety.
