Frequently Asked Questions
Lug type valves, like the F170, feature threaded inserts that allow them to be bolted directly to the pipe flange, enabling the valve to be used for end-of-line service where piping can be disconnected from one side.
Choice depends on temperature and chemistry: EPDM for general water/steam, PTFE for extreme chemicals/high heat (-50 to 200°C), and Viton for oil-based media.
Yes, it is designed to meet ANSI 125/150, PN10, PN16, and 10K standards, ensuring stability and safety in high-pressure environments.
For highly corrosive media, we recommend ASTM A351 CF8 or CF8M Stainless Steel, which provides superior resistance to oxidation and chemical attack.
While they can withstand lower temperatures without permanent damage, the elastomer becomes harder, which typically increases the required operating torque.
Yes, the Series F170 is designed for compatibility with pneumatic and electric actuators to facilitate automated flow management in industrial systems.
