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 精密真空調節(jié)器 (evr) 是專門為在各種不同的輸入條件下控制高度穩(wěn)定的入口壓力而設計的。由于供應真空的變化或流量的變化, 這些調節(jié)器的效果很小。equilibar 精密真空調節(jié)器的工作方式不同于傳統(tǒng)的真空控制閥設計。evr 使用柔性隔膜作為唯一的運動部件。該隔膜用于直接密封內(nèi)部閥門孔, 消除了傳統(tǒng)真空控制閥中常見的 “粘附”, 這些閥依賴于動態(tài) o 形圈或雨刮器型密封件。equibar 的設計是無摩擦的, 可以控制真空與非常高的分辨率。
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.?我們的低流量精密真空調節(jié)器的尺寸從 “到 1” 不等, 可根據(jù)溫度和耐化學性的應用要求選擇不銹鋼、陽極氧化鋁或 pvc。每個 evr 都配有手動導頻設定值調節(jié)器, 方便旋鈕調整。
