Gate valves are generally used to completely shut off fluid flow or, in the fully open position, provide full flow in the pipeline. Thus they are used either in fully closed or fully open positions.
DIN3352 is the production standard of the German standard valve, which includes metal sealing valves and soft sealing valves.
F5 is the face-to-face length of the German standard valve, which is included in the DIN3202 standard, and the corresponding is F4. In contrast, the F5 structure length is longer than the length of F4.
NRS is a Non-Rising Stem, which refers to a Non-Rising gate valve. The Non-Rising gate valve is also referred to as a rotary gate valve, which is rotated during the opening and closing process. The handwheel drives the valve stem rotation, the valve stem is driven up and down, and the switching process is completed. When the non-rising gate valve is opened, the valve stem is only rotating, there is no action of up and down.

The body material of NRS DIN3352 F5 Flanged Gate Valves VS O.S.&Y. can be CI/DI/WCB/SS, compared the weight, the same size O.S.&Y. gate valve is heavier that NRS gate valve
Both NRS DIN3352 F5 Flanged Gate Valves VS O.S.&Y. DIN3352 F5 flanged gate valve pressure can be PN10/16.
Stardard:DIN 3352
Face to face:DIN 3202 F4/F5
Connection flange type:DIN standard
The height of the non-stem&yoke gate valve is lower than the rising stem, suitable for installation on the ground, while the opening time is short, suitable for large diameter or limited installation space installation environment

Yes. Before shipment, we will arrange the pressure test for each piece of gate valve to avoid the leakage problem.
