 よくある質問 | よくある質問

Q1: What is the difference between NRS gate valve and OS&Y gate valve?

あ: The NRS (concealed stem) gate valve does not raise or lower the valve stem during operation and is suitable for underground installations and valve wells with limited clearance. The valve stem of the OS&Y (rising stem) gate valve rises and falls during operation, providing a visual indication of the valve position. It is suitable for occasions on the ground where visual confirmation of the switch status is required.

第2四半期: What is the difference between elastic wedge gate valve (soft seal) and hard seal gate valve?

あ: The gate plate of the elastic wedge gate valve (soft seal) is entirely covered with EPDM rubber, providing a zero-leakage seal (bubble level) and suitable for water, sewage and mild chemicals. Hard-sealed gate valves (metal-to-metal) are suitable for high temperatures (>150℃) and abrasive media, but have higher leakage rates. For most water supply and HVAC applications, resilient wedge gate valves are the most cost-effective option.

Q3: What is the maximum working pressure and temperature of this gate valve?

あ: The standard configuration provides two pressure levels, PN10 and PN16, with a temperature range of -10°C to +80°C. For higher temperatures or pressures, please contact our sales team for custom options.

Q4: Is this valve suitable for drinking water systems?

あ: はい. This valve uses lead-free EPDM sealing material, meets drinking water safety standards, and can be safely used in drinking water distribution systems.

Q5: What is the minimum order quantity?

あ: The minimum order quantity for standard orders is 1 piece. Customization services (サイズ, 色, 梱包, logo) please contact our sales team for details.
