UHP PTFE 氟聚合物背压调节器（1/2 英寸）- BR-08 系列 | #BR-08-52612

BR-08 系列 PTFE 背压调节器适用于超高纯度和腐蚀性流体处理系统。其非泄压设计要求整个阀门有 5 psi 的压差，从而获得更好的下垂特性和低滞后。派克 BR-08 系列是 1/2 英寸 PTFE 氟聚合物背压调节器，设计用于超高纯度 (UHP)、去离子水、腐蚀性化学品和浆液分配系统，包括用于半导体制造和清洁的系统- 区域应用程序。它的非泄压设计要求阀门两端的压差为 5 psi，从而在高达 120 psig 的流体处理系统中实现低滞后、更好的下垂特性和稳态压力控制。

BR-8 采用机加工 PTFE 主体，带有精密加工的阀座和隔膜密封区域，具有出色的泄漏完整性和耐化学性。大隔膜允许对下游变化更敏感，防止压力波动的影响被传递到上游。其不锈钢弹簧可减少腐蚀性环境的影响，并确保与各种腐蚀性过程介质的兼容性。

为了提高灵活性，BR-08 系列可配备多种端口配置，包括 1/2 和 3/4 英寸 Parbond 和 Parflare 管接头。这些配件减少了组装时间和安装成本，同时确保在清洁度至关重要的应用中实现可靠密封。

BR-08 系列背压调节器的舌槽密封确保隔膜与阀体之间的正向密封，将过程介质与大气隔离，并为弹簧和调节螺钉提供额外的保护。调节器配有定位安装环和流向箭头，便于安装并节省时间。

The BR-08 Series PTFE Back Pressure Regulator is suited for ultra-high purity and aggressive fluid handling systems. Its non-relieving design requires a 5 psi differential across the valve, resulting in better droop characteristics and low hysteresis. Parker BR-08 Series is a 1/2 inch PTFE fluoropolymer back pressure regulator that is designed for use in ultra-high purity (UHP), DI water, aggressive chemical, and slurry distribution systems, including those used in semiconductor manufacturing and clean-area applications. It’s non-relieving design requires a 5 psi differential across the valve, which leads to low hysteresis, better droop characteristics, and steady-state pressure control in fluid handling systems up to 120 psig.

The BR-8 utilizes a machined PTFE body with a precision-machined seat and diaphragm sealing area for superior leak integrity and chemical resistance. The large diaphragm allows for greater sensitivity to changes downstream, preventing the effects of pressure surges being transferred upstream. Its stainless steel spring reduces the effects of corrosive environments and ensures compatibility with a wide range of aggressive process media.

For increased flexibility, the BR-08 Series can be fitted with a variety of port configurations, including 1/2 and 3/4 inch Parbond and Parflare tube fittings. The fittings reduce assembly time and installation costs, while ensuring a leak-tight seal for reliability in applications where cleanliness is critical.

The tongue and groove seal of the BR-08 Series back pressure regulator ensures a positive diaphragm to body seal, which isolates process media from the atmosphere and provides added protection for the spring and adjusting screw. The regulator comes equipped with a positional mounting ring and flow direction arrow for ease of installation and time savings.
