Frequently Asked Questions
Lug type valves have threaded inserts (lugs) that allow them to be bolted directly to the pipe flange, enabling the valve to be used for end-of-line service where one side of the piping can be disconnected without removing the valve.
For high temperatures, PTFE (-50 to 200°C) or Viton (-12 to 230°C) are recommended due to their superior thermal stability and chemical resistance.
Yes, the Series F101 is compatible with both electric and pneumatic actuators for sizes ranging from 1½″ up to 48″, allowing for full integration into automated control systems.
To prevent corrosion, we offer Stainless Steel (ASTM A351 CF8, CF8M, CF3, CF3M) and Ductile Cast Iron options depending on the aggressiveness of the medium.
Yes, our valves are manufactured to meet ANSI 125/150, PN10, PN16, and JIS 10K standards to ensure compatibility with worldwide piping infrastructure.
The lug design provides superior support and a more secure mechanical connection to the pipeline, reducing the risk of movement or failure under high-pressure flow conditions.
