GENERANT安全阀Brass CRV系列介绍
描述
Generant 黄铜 CRV 系列低温安全阀是一种弹簧参考过压保护装置。 CRV 结合了独有的“污垢防护”以防止系统碎片，非常适合作为低温系统中的“安全阻塞线路”。 CRV 按照 O2 服务标准提供清洁和包装。该阀门可在工厂预设为 10 至 750 Psig（0.7 至 51.7 Bar）并永久锁定。阀座和提升阀几何形状与优化的弹簧范围相结合，可提供高流量和微小的压力积累。释放压力可以排放到大气或下游连接。
CRV 配有用于 10 – 49 Psig (0.7 – 3.4 Bar) 的设定压力的氟硅酮密封件和用于 50 – 750 Psig (3.5 – 51.7 Bar) 的设定压力的 PCTFE 密封件。
特征
• 可用的CE 标志：“CE 标志”符合压力设备指令(PED) 的要求。
• 独家“DIRT GUARD”提升阀：包含提升阀网以延长阀门寿命并确保可靠性。
• 针对高流量进行了优化：高流量和出色的复位性能。
• 防篡改：提供工厂预设并永久锁定以进行防篡改服务。
• 可配置：排放到大气或多种入口和出口管道配置，可选的导流帽可用于转移废气。
• 100% 工厂测试：针对泄漏、裂纹和复位性能进行了测试。
• 与氧气服务兼容：清洁和包装符合氧气服务标准。
Description
The Generant Series Brass CRV, Cryogenic Relief Valve is a spring reference over pressure protection device. Incorporating the exclusive “Dirt Guard” to protect from system debris, the CRV is ideally suited as a “Blocked Line Safety” in cryogenic systems. The CRV is supplied cleaned and packaged for O2 service standard. This valve can be ordered factory preset from 10 to 750 Psig (0.7 to 51.7 Bar) and are permanently locked. Seat and poppet geometry combined with optimized spring ranges provide high flow with minimum pressure accumulation. Relief pressure can be discharged to atmosphere or to a downstream connection.
The CRV is supplied with Flourosilicone seals for set pressures from 10 – 49 Psig (0.7 – 3.4 Bar) and PCTFE seals for set pressures 50 – 750 Psig (3.5 – 51.7 Bar).
Features
• AVAILABLE CE MARKED: “CE Marked” in accordance with the requirements of the Pressure Equipment Directive (PED).
• EXCLUSIVE “DIRT GUARD” POPPET: Incorporates a poppet screen to extend valve life and ensure reliability.
• OPTIMIZED FOR HIGH FLOW: High Flow Capacity and Excellent Reseat Performance.
• TAMPER PROOF: Supplied Factory Preset and Permanently Locked for Tamper Proof Service.
• CONFIGURABLE: Discharge to Atmosphere or a Wide Variety of Inlet and Outlet piping configurations, Optional Deflector Cap available for diverting exhausted gas.
• 100% FACTORY TESTED: Tested for Leakage, Crack and Reseat performance.
• OXYGEN SERVICE COMPATIBLE: Cleaned and Packaged for Oxygen Service standard.
