NRS Gate Valve

An NRS Gate Valve, or Non-Rising Stem Gate Valve, operates using a threaded stem that remains stationary while the gate moves up and down to control the flow. The stem is threaded on the inside and is directly connected to the gate. When the handwheel is rotated, the gate moves along the stem's threads, enabling the valve to open or close without the stem rising. This design is particularly useful in applications where vertical space is limited.
