The DIN3202 F4 NRS Cast Steel Gate Valve is a robust industrial valve designed for reliable flow control. It adheres to the DIN3202 F4 standard, specifying a "short" face-to-face length for compact installation.
Key Features
NRS (Non-Rising Stem): The stem threads remain inside the valve, making it ideal for tight spaces where vertical clearance is limited.
Material: Built from cast steel, providing high tensile strength and durability for high-pressure or high-temperature applications.
Design: Features a wedge gate mechanism for a tight seal and minimal pressure drop.
It is commonly used in water treatment, oil, and gas industries where space-saving and structural integrity are priorities.
