Choosing PN10/16 Resilient Seated Non Rising Stem Gate Valve DIN3352-F4, DN50-DN600: Working Requirements and Integration Fit

1. Start with your service conditions

Write down your line requirements before you compare any valve:

• Medium: what fluid will pass through the valve?
• Operating pressure: what is the nominal pressure class of the line?
• Temperature: what are the lowest and highest temperatures the fluid will reach?
• Pipe size: what nominal diameter (DN) is the line?
• Connection standards: which face-to-face and flange standards does the existing pipework use?

With these answers you can check each point against the product data below.

2. Pressure class and test pressures

The valve has two pressure ratings:

Choose the pressure class that matches your system's design pressure. The seal and shell test values are the published test pressures. They are not operating limits, so the system should run within the nominal pressure of the class you choose.

3. Medium and temperature range

The published suitable medium is water. The suitable temperature range is -10 to 80℃.

When this valve does not apply: the confirmed material only covers water service. If your project carries another medium, or the temperature goes outside -10 to 80℃, this product description does not support the application. Ask the supplier for confirmed data before you consider it.

4. Main parts and materials

The disc is listed as GGG50 with either an NBR or an EPDM resilient covering. That is why the valve is described as resilient seated. Tell the supplier which elastomer (NBR or EPDM) your specification or water service requires.

5. Non-rising stem design

The valve uses a non-rising stem design. If your installation has limited space above the valve, include this in your fit check. Confirm the overall dimensions with the supplier, because no height data is included in the published material.

6. Standards and connection fit

• Design and manufacture: DIN3352
• Face to face: DIN3202 F4/F5
• Flange end: BS EN1092-2:1997

The product name refers to DIN3352-F4, but the published face-to-face reference lists DIN3202 F4/F5. Confirm which face-to-face length you need so that the valve fits the space in your existing or planned line. Also check that the mating flanges follow BS EN1092-2:1997 drilling at your chosen PN class.

7. Size range

The published sizes are DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN350, DN400, DN450, DN500 and DN600. Sizes outside this list are not covered by this product description.

Selection checklist

1. The medium is water.
2. Operating temperature stays within -10 to 80℃.
3. System pressure is within PN10 (1.0 MPa) or PN16 (1.6 MPa), and you have chosen the class.
4. Pipe size is one of the listed sizes from DN50 to DN600.
5. The pipework uses DIN3202 F4/F5 face-to-face and BS EN1092-2:1997 flange connections.
6. You have specified NBR or EPDM for the disc covering.
7. A non-rising stem suits your installation space and operation.

What to confirm before ordering

The published material does not include prices, lead times, certifications or approvals for specific markets. If your project in the United States, the Middle East, Europe or Southeast Asia needs particular approvals, documents or inspection, raise these requirements with HEBEI YONGQIAN TRADING CO.,LTD. and get them confirmed in writing.
