Frequently Asked Questions
Lug type valves have threaded inserts (lugs) that allow them to be bolted directly to the flange, enabling them to be used for dead-end service where the piping can be disconnected from one side without removing the valve.
Selection depends on temperature and chemicals. For high temperatures up to 200°C, PTFE is recommended. For general use, EPDM or NBR are suitable, while Viton is ideal for chemical resistance.
Yes, it is designed to meet ANSI 125/150, PN10, PN16, and JIS 10K standards, ensuring it fits most global industrial piping systems.
Absolutely. By selecting Stainless Steel (CF8/CF8M) for the body and disc, and PTFE or Viton for the seat, the valve provides excellent resistance to corrosive media.
NBR seats are typically rated for temperatures between -20°C and 100°C (-4°F to 212°F).
The Series F170 is available in a wide range of sizes, from 1.5 inches (40mm) up to 24 inches (600mm).
