1/2″ EVR-GDS4 with Manual Pilot Setpoint Adjuster
HIGH RESOLUTION AND ACCURACY FOR PIPING SIZES 1/4″ TO 1″
Equilibar precision vacuum regulators (EVR) are designed specifically to control a highly stable inlet pressure across widely varying input conditions. These regulators show very little effect due to variation in supply vacuum or changes in flow rate. Equilibar precision vacuum regulators work differently than traditional vacuum control valve designs. The EVR uses a flexible diaphragm as the only moving part. This diaphragm is used to directly seal against the internal valve orifices, eliminating the “stiction” commonly found in traditional vacuum control valves that rely on dynamic O-ring or wiper type seals. The Equilibar design is frictionless and can control vacuum with very high resolution.
equibar 精密真空调节器 (evr) 是专门为在各种不同的输入条件下控制高度稳定的入口压力而设计的。由于供应真空的变化或流量的变化, 这些调节器的效果很小。equilibar 精密真空调节器的工作方式不同于传统的真空控制阀设计。evr 使用柔性隔膜作为唯一的运动部件。该隔膜用于直接密封内部阀门孔, 消除了传统真空控制阀中常见的 “粘附”, 这些阀依赖于动态 o 形圈或雨刮器型密封件。equibar 的设计是无摩擦的, 可以控制真空与非常高的分辨率。
Our lower flow precision vacuum regulators are available in sizes ranging from 1/4″ to 1″ with material options of stainless steel 316/316L, anodized aluminum or PVC depending on the application requirements for temperature and chemical resistance. Each EVR is delivered with a manual pilot setpoint regulator for convenient knob adjustment. 我们的低流量精密真空调节器的尺寸从 “到 1” 不等, 可根据温度和耐化学性的应用要求选择不锈钢、阳极氧化铝或 pvc。每个 evr 都配有手动导频设定值调节器, 方便旋钮调整。
