PARKER Needle Valve, Toggle Valve - VQ Series Needle Valve
針閥、撥動閥-VQ系列針閥

PARKER VQ系列撥動閥是一種快速作用的閥門，適用于具有低壓（300磅/平方英寸）要求的簡單開啟或關(guān)閉系統(tǒng)。帕克的VQ系列撥動閥是在中等壓力和溫度應(yīng)用中手動或氣動開關(guān)控制的性能和值的正確組合。手動型采用一個撥動手柄，可在壓力高達300 psig（21 bar）時快速動作。緊湊型雙作用、常閉和常開氣動閥門是600 psig（41 bar）壓力下自動控制的理想選擇。

Parker's VQ Series toggle valves are quick acting valves for simple open or close systems with low pressure (300 PSI) requirements.Parker’s VQ Series Toggle Valves are the right combination of performance and value for manual or pneumatic on-off control in moderate pressure and temperature applications. The manual version employs a toggle handle for quick action at pressures up to 300 psig (21 bar). Compact double acting, normally closed, and normally open pneumatically actuated versions of this valve are ideal for automatic control at pressures up to 600 psig (41 bar).
