Product Overview

The FIVC Gate Valve is designed for dependable full-flow isolation in water systems. Its straight-through design ensures minimal pressure loss, while the robust ductile iron construction delivers long-term durability and tight shut-off performance. The rising stem design also provides clear visual confirmation of valve position while keeping critical threads outside the flow for improved reliability.

Frequently Asked Questions
What type of valve is this? +
"It is a linear-operated gate valve designed for full-flow pipeline isolation. The valve operates by raising or lowering a wedge to open or close the flow path."
Is the valve CE marked? +
No. According to PED 2014/68/EU Art. 4.3, it is manufactured under Sound Engineering Practice (SEP) and therefore exempt from CE marking.
What stem types are available? +
"The valve is available in both rising stem and non-rising stem configurations. What this means in practice: Rising stem: The stem moves upward when the valve opens, providing clear visual position indication. Non-rising stem: The stem remains in position while operating, making it suitable for installations with limited vertical space."
What is the advantage of a full-flow gate valve design? +
"A gate valve: Provides minimal pressure loss when fully open Maintains full flow capacity Reduces unnecessary turbulence Supports efficient system operation This makes it ideal for isolation in systems where flow performance is important."
Can this valve be used for flow regulation? +
"No. Gate valves are designed for isolation only and should be operated in fully open or fully closed positions. For continuous regulation or throttling, a globe valve or control valve is typically the better engineering choice."
