Zasuwy odgrywają kluczową rolę w kontrolowaniu przepływu cieczy w instalacjach przemysłowych i komunalnych. Różne typy, jak zasuwa BS5163 PN16, Zasuwa zasuwowa BS5163 z elastycznym gniazdem, I zasuwa o dużych rozmiarach, cater to varying applications based on their pressure resistance, budowa, and specific features. Here’s a detailed look into their pressure handling capabilities, application areas, and how to choose the right valve.
Pressure Resistance of Gate Valves
- BS5163 Gate Valve PN16: These valves are designed to withstand a maximum pressure of 16 bar (232 psi), ideal for waterworks and industrial applications. The resilient seated design ensures leak-proof performance, especially at temperatures between -10°C to +80°C.
- Big Size Gate Valve: For larger systems, these valves offer a pressure rating of PN10 or PN16. Their robust ductile iron construction allows them to handle heavy-duty applications without compromising performance.
- Other Variants: Rising stem and non-rising stem gate valves also differ in pressure resistance, often determined by their material and design standards like API600 or DIN3352.
Applications of Gate Valves
Gate valves are versatile, finding usage in:
- Water Supply Systems: Commonly used in municipal water networks and industrial cooling systems.
- Wastewater Treatment: Zasuwa zasuwowa BS5163 z elastycznym gniazdem is preferred for its reliability and tight seal.
- Olej & Gas Industry: Big size valves control flow in pipelines, ensuring minimal resistance and high efficiency.
- Fire Protection: Their superior sealing performance makes them a staple in fire suppression systems.
| Valve Type | Ciśnienie (bar) | Aplikacja |
|---|---|---|
| BS5163 Gate Valve PN16 | Up to 16 | Waterworks, industrial pipelines |
| Big Size Gate Valve | PN10/PN16 | Large-scale fluid control systems |
| Zawór zasuwający z wznoszącym się trzpieniem | Variable | Olej, gaz, and municipal pipelines |
| Zasuwa zasuwowa z niewznoszącym się trzpieniem | Variable | Underground installations |
How to Choose the Right Gate Valve
- Pressure Requirements: Ensure compatibility with the system’s maximum operating pressure. For systems requiring resilience and durability, the BS5163 resilient seated gate valve is an excellent choice.
- Size and Flow Needs: For large pipelines, opt for big size gate valves to reduce fluid resistance.
- Stem Design: Choose between rising or non-rising stems based on the installation space and visibility requirements.
Differences Between Gate Valve Types
- BS5163 Gate Valve PN16 vs. Big Size Gate Valve: While both are durable, the former focuses on medium-scale waterworks, and the latter excels in large-scale applications.
- Rising Stem vs. Non-Rising Stem: Rising stem provides visual indication of valve position, whereas non-rising stem saves space and is ideal for underground installations.
- Material Construction: Ductile iron valves like the big size gate valve offer higher tensile strength compared to cast iron valves.
Crafting Reliable Systems with the Right Gate Valve
Selecting the correct gate valve ensures system efficiency, niezawodność, and longevity. Whether you choose the BS5163 resilient seated gate valve, Zasuwa zasuwowa BS5163 PN16, or big size gate valve, understanding their unique features will help you match them to your specific needs. Always prioritize quality, trwałość, and compatibility when choosing a valve to maintain seamless operation in your fluid systems.
