Frequently Asked Questions
Lug type valves have threaded inserts (lugs) that allow the valve to be bolted directly to the pipe flange, enabling it to be used for dead-end service where the piping can be disconnected from one side without removing the valve.
For high-temperature environments, PTFE is highly recommended as it can withstand temperatures up to 200°C, and Viton is suitable for up to 230°C depending on the specific application.
Yes, the F170 series is manufactured to meet ANSI 125/150, PN10, PN16, and 10K standards, ensuring compatibility with global industrial piping specifications.
Absolutely. We offer various materials including Stainless Steel (ASTM A351 CF8/CF8M) and Al-Bronze to provide the necessary chemical resistance for your specific medium.
At very low temperatures, elastomer seats may become harder, which can increase the torque required to operate the valve, although the seat typically remains undamaged.
The F170 series covers a wide spectrum of sizes, starting from 1½ inches (40mm) up to 24 inches (600mm) to accommodate various flow requirements.
