派克 Autoclave Engineers RVS系列軟座安全閥
Autoclave Engineers RVS 系列安全閥 - 20,000 PSI | #10RVS9072


派克 Autoclave Engineers 安全閥為 1,500 psi (103 bar) 至 20,000 psi (1378 bar) 的設定壓力提供可靠的氣體排放。軟閥座設計提供氣密密封、可重復彈出和重新安裝。這些精密閥門專為零泄漏至關重要的壓力氣體系統而設計。Parker Autoclave 的 RVS 系列安全閥采用軟閥座設計，可在 1500 psi (103 bar) 至 20000 psi (1378 bar) 的設定壓力下可靠地排放氣體。工作溫度范圍為 32°F (0°C) 至 400°F (204°C)。軟閥座設計提供氣密密封、可重復彈出和重新安裝。此外，軟座閥提供比金屬座減壓閥更高的循環壽命。

這些精密安全閥專為壓力氣體系統而設計，其中零泄漏至關重要。不建議將它們用于液氮或液態二氧化碳，因為它們在釋放時會在低溫下產生氣體。它們被設計成與壓力增加成比例地打開。因此，不建議將它們用于需要在設定壓力下立即全閥流量的應用（例如分解、聚合等）。溢流閥的全流量定義為超過設定壓力 10%。

選項：Autoclave Engineers可以根據特殊訂單提供各種入口和出口連接。

注意：
1. 派克 Autoclave 安全閥已預設并在工廠密封。如果客戶破壞密封，則保修無效。
2. 最大系統工作壓力不應超過安全閥設定壓力的 90%。超過此壓力的工作壓力可能會導致滲漏，從而損壞塞子和閥座。

Parker Autoclave's RVS Series relief valves provide reliable venting of gases for set pressures from 1,500 psi (103 bar) to 20,000 psi (1378 bar). The valve's soft seat design provides bubble tight sealing, repeatable pop-off, and reseat capability.

Parker Autoclave's RVS Series relief valves are designed with a soft seat design for reliable venting of gases at set pressures from 1500 psi (103 bar) to 20000 psi (1378 bar). The operating temperature range is 32°F (0°C) to 400°F (204°C). The soft seat design provides bubble tight sealing, repeatable pop-off, and reseat. Additionally, soft seat valves provide a higher cycle life than metal seat relief valves.

These precision relief valves are designed for pressure gas systems, where zero leakage is critical. They are not recommended for liquid nitrogen or liquid carbon dioxide, which produce gas at cryogenic temperatures upon relief. They are designed to open proportionally to increasing pressure. Therefore, they are not recommended for applications requiring immediate full valve flow at set pressure (such as decompositions, polymerizations, etc.). Full flow of relief valve is defined at 10% over set pressure.

Options: Autoclave Engineers can supply various inlet and outlet connections on special order.

CAUTION:
1. Parker Autoclave relief valves are preset and factory sealed. Warranty is voided if seal is broken by customer.
2. Maximum system operating pressure should not exceed 90% of relief valve set pressure. Operating pressures in excess of this may cause weepage resulting in damage to the plug and seat.

Markets:
- Oil and Gas
- Petrochemical
- Chemical
- Research

Features/Benefits:
- Standard models of Relief Valves are constructed of 316 stainless steel with selected components
- made of anti-galling stainless steel material for optimum economy and ruggedness.
- Designed with 9/16” Parker Autoclave Engineers Medium Pressure inlet connections. The outlet connection on all models is a female 3/4” NPT. While adapters to other sizes and connection types are available, they must be sized for specific flow requirements.
- Orifice diameters range from .062 (1.57mm) to .312” (7.92mm).
- Designed to open as a function of increasing system pressure. Proper spring selection assures repeatability of opening, full lift and flow, and reseat pressures.
- Materials engineering and stringent quality control procedures combine to assure the highest quality, reliability and service life. Each valve is preset and factory sealed to ensure proper valve operation.
- Unique seat construction plus over-the-nozzle guiding and proper selection of materials permits standard set pressures to 75,000 psi. (5171 bar)
- Designed to provide bubble tight shut off of gases.
- Engineered to perform with fewer basic components, RVS valves facilitate minimum stocking of spare parts and ease of maintenance
- Available with CE Mark. SOG option available upon request.


Applications:
- Pressure Gas Systems
- Cryogenic systems
- Steam Handling Systems
