Fisher™ EZR 型泄压阀或背压调压器

费希尔Fisher EZR 型先导式泄压阀或背压调压器通常在城市门站和区站中用作过压保护泄压阀，或在商业和工业应用中用作背压调压器。 其运行安静、顺畅，关断严密且使用寿命长，即使在脏污的工况下也能有很好的表现。广州奥丽斯特燃气设备有限公司是美国FISHER产品华南区域（广东省）艾默生集团授权代理商。2020美国FISHER技术选型020*叁贰贰0162张S中国费希尔调压网www.zgfisher.com 【张工15876552411手机同微XIN】

功能

运行安静—标准阀笼可实现一流的减噪效果，使 EZR 产品较同类的柔性元件调压器噪声低 6-8 dBa。

更大的液体处理能力—EZR 系列的流体路径可获得最佳的液体处理能力，且运行极为安静。 Fisher™ 产品经实验室检测，其公布的产品流体数据皆能 100% 实现。

使用寿命长—经现场验证的阀膜具有分层纤维结构，凸起式焊边和模制形状，从而具有更高的强度、更好的耐用性和更长的使用寿命。

防碎屑保护—EZR 系列阀笼创新性的流体通路可以减少碎屑带来的损伤，而不锈钢入口粗滤器可以防止大块的碎屑损伤阀膜。

严密关断—金属塞设计可使颗粒和碎屑偏离阀膜，带来卓越的关断效果，延长维护间隔。

行程指示器—简化了维护过程的检测和系统故障排查

功能多样—通过将泄压先导系统转变为减压先导系统，EZR 型泄压阀或背压调节器可以轻松地转变为减压调压器。

Fisher Type EZR pilot-operated, pressure relief valve or backpressure regulator is typically used in city gate and district stations as a relief valve for overpressure protection, or in commercial and industrial applications as a backpressure regulator. It provides smooth, quiet operation, tight shutoff, and long life, even in dirty service.

Features

Quiet Operation—The standard cage provides best-in-class noise reduction, making the EZR Series 6-8 dBa quieter than comparable flexible element regulators.

High Capacity—The flow path of the EZR Series produces best-in-class capacity combined with the quietest operation. Fisher™ products are laboratory tested so 100% of the published flow capacity can be used with confidence.

Long Life—The field proven dipahragm design incorporates layered fabric, a raised bead edge and molded shape to increase strength, durability, and service life

Debris Protection—The revolutionary flow path of the EZR Series cage minimizes the damage from debris while the stainless steel inlet strainer prevents large particles from damaging the diaphragm.

Tight Shutoff—The metal plug is designed to deflect particles and debris away from the diaphragm, providing superior shutoff and increasing the time between maintenance intervals.

Travel Indicator—Simplifies in-service inspection and system troubleshooting

Versatility—By changing from a relief piloting system to a pressure reducing piloting system, a Type EZR relief valve or backpressure regulator easily becomes a pressure reducing regulator.
