Equilibar 4″ EVR-BD32 vacuum regulator with PVC body and manual pilot setpoint control
Precision High Flow Vacuum Valves?精密高流量真空閥
Equilibar’s precision high flow vacuum regulating valves offer unique performance advantages for pipe sizes up to 4″ in size.? equibar 的精密高流量真空調節(jié)閥為尺寸不超過4英寸的管道提供了獨特的性能優(yōu)勢。
Equilibar’s patented technology offers lightning-fast response that is mechanically native, with zero hysteresis or deadband.?Equilibar precision vacuum regulators work differently with a flexible diaphragm as the only moving part. This diaphragm directly seals against the internal valve orifices, eliminating the “stiction” commonly found in traditional vacuum control valves with dynamic O-ring or wiper type seals. The Equilibar design is frictionless and can control vacuum with very high resolution.?equilibar 的專利技術提供了機械上的閃電般的快速響應, 零滯后或死帶。equilibar 精密真空調節(jié)器以柔性膜片作為唯一的移動部件, 以不同的工作方式工作。這種隔膜直接密封內部閥門孔, 消除了傳統(tǒng)真空控制閥中常見的 “粘附”, 帶有動態(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。詳細了解它們的工作原理。
Our precision high flow vacuum valves are available in sizes ranging from 1 1/2″ to 4″ 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.? 我們的精密高流量真空閥的尺寸從 1 “到 4” 不等, 可根據溫度和耐化學性的應用要求提供不銹鋼的材料選擇。每個 evr 都配有手動導頻設定值調節(jié)器, 方便旋鈕調整.
