Autoclave Engineers RVS 系列安全阀 - 20,000 PSI | #10RVS9072


派克 Autoclave Engineers 安全阀为 1,500 psi (103 bar) 至 20,000 psi (1378 bar) 的设定压力提供可靠的气体排放。软阀座设计提供气密密封、可重复弹出和重新安装。这些精密阀门专为零泄漏至关重要的压力气体系统而设计。Parker Autoclave 的 RVS 系列安全阀采用软阀座设计，可在 1500 psi (103 bar) 至 20000 psi (1378 bar) 的设定压力下可靠地排放气体。工作温度范围为 32°F (0°C) 至 400°F (204°C)。软阀座设计提供气密密封、可重复弹出和重新安装。此外，软座阀提供比金属座减压阀更高的循环寿命。

这些精密安全阀专为压力气体系统而设计，其中零泄漏至关重要。不建议将它们用于液氮或液态二氧化碳，因为它们在释放时会在低温下产生气体。它们被设计成与压力增加成比例地打开。因此，不建议将它们用于需要在设定压力下立即全阀流量的应用（例如分解、聚合等）。溢流阀的全流量定义为超过设定压力 10%。

选项：Autoclave Engineers可以根据特殊订单提供各种入口和出口连接。

注意：
1. 派克 Autoclave 安全阀已预设并在工厂密封。如果客户破坏密封，则保修无效。
2. 最大系统工作压力不应超过安全阀设定压力的 90%。超过此压力的工作压力可能会导致渗漏，从而损坏塞子和阀座。

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.
