Parker Pressure Relief Valves
RVP 系列 5171 bar溢流阀Relief Valve, RVP Series - 75,000 PSI

RVP 系列 5171 bar溢流阀用于高压灭菌器,可对工作气体或流体提供可靠的卸压压力在 103-5171 bar之间。 Parker Autoclave's RVP Series relief valves provide reliable venting of gases for set pressures from 3,000 psi (206 bar) to 75,000 psi (5171 bar). The valve's metal seat design provides shut-off of liquids and gases to commercial standards.

Parker Autoclave的RVP系列溢流阀采用金属阀座设计，可在3,000 psi（206 bar）至75,000 psi（5171 bar）的设定压力下安全稳定地排放气体，工作温度范围为-423°F(-252° C)到400°F(204°C)。这些精密溢流阀设计用于在对流量要求不高应用中，这些应用主要包含高压下的热膨胀或低容量泄压，因此这些型号的液体曲线在目录中没有显示。 Parker Autoclave's RVP Series relief valves are designed with a metal seat design for reliable venting of gases at set pressures from 3,000 psi (206 bar) to 75,000 psi (5171 bar). The operating temperature range is -423°F (-252°C) to 400°F (204°C).These precision relief valves are designed for thermal expansion or low volume relief applications at high pressures where flow is not critical. Thus, liquid curves for these models are not shown in the catalog

Parker 高压灭菌器可以根据特殊订单提供各种进口和出口连接。对于RVP型号，高温选项也适用于750°F（399°C）的温度。指定高温选项：为750°F(399°C)高温选项添加后缀"HT”。 Parker Autoclave can supply various inlet and outlet connections on special order. A high temperature option is also available for temperatures to 750°F (399°C) for RVP models. To specify high temperature option: Add suffix “HT” for 750°F (399°C) high temperature option.

警告Caution:
1. AE泄压阀是预设和工厂密封的。如果密封被客户破坏，保修是无效的。 AE relief valves are preset and factory sealed. Warranty is voided if seal is broken by customer.
2. 系统工作压力不应超过安全阀设定压力的90％。 Maximum system operating pressure should not exceed 90% of relief valve set pressure.

特点/优势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 3/8” and 5/16” Parker Autoclave high 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.
- 安全阀的标准型号由316不锈钢制成，所选部件由防磨损不锈钢材料制成，以实现理想的经济性和坚固性。
- 采用"3/8"和"5/16”Parker高压灭菌器高压入口连接设计。出口连接均为"3/4"NPT内螺纹。尽管其他尺寸和连接类型的适配器都可用，但应根据特定的流量要求进行调整。
- 孔径范围从.062 (1.57mm)到.312(7.92mm)。
- 随着系统压力的增加而打开。正确的弹簧选择保障开启，完全升降和流动的可重复性，以及重置压力。
- 材料工程和严格的质量控制程序相结合，以获得更高的质量，稳定性和使用寿命。每个阀门都预先设定好并在工厂密封，以保障阀门正常工作
- 新颖的底座结构，加上喷嘴引导和适当的材料选择，可使标准设定压力达到75,000 psi。 (5171bar)
- 设计用于提供气密关闭气体。
- RVS阀设计用于减少基本部件的使用，从而减少备件的存放量，并便于维护。
- 提供CE标志。 SOG选项可根据要求提供。
