Fisher™ EZR 系列减压

功 能

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。

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。

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。

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。

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。

行程指示器—简化了维护过程的检测和系统故障排查

高精度—161EB 系列、161AY 系列和 PRX/120 先导型提供了多出口压力范围和窄比例段，赋予 EZR 系列紧密且精确的控制能力。

一体化切断—EZR-OSX 型切断在出现过压或失压时会中断供气。

Type EZR pilot-operated, pressure reducing regulator designed to give accurate, smooth, quiet operation, tight shutoff, and long life, even in dirty service. EZR Series can be installed in various applications such as natural gas transmission/distribution systems, industrial and commercial facilities. The Type EZROSX is available with a slam-shut device which provides overpressure protection and/or under pressure protection by completely shutting off the flow of gas to the downstream system.

Features

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.

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.

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

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

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.

Travel Indicator—Simplifies in-service inspection and system troubleshooting

High Accuracy—Multiple outlet pressure ranges and narrow proportional bands offered by the 161EB Series, 161AY Series and Type PRX/120 pilots provide the EZR Series with tight, accurate control.

Integrated Slamshut—Type EZR-OSX slam-shut interrupts gas service during an overpressure or underpressure condition.
