FAQ:

1. What is the difference between resilient-seated and metal-seated gate valves?

Resilient-seated gate valves are typically used in water and sewage systems, as the soft EPDM seat provides a tight seal even under moderate pressures. Metal-seated valves, on the other hand, are better suited for high-pressure and high-temperature applications.

2. What is the maximum pressure rating for your resilient-seated gate valve?

Our resilient-seated gate valve is rated for PN10/16, making it suitable for most water and wastewater systems.
