PARKER Needle Valve, Toggle Valve - VQ Series Needle Valve
针阀、拨动阀-VQ系列针阀

PARKER VQ系列拨动阀是一种快速作用的阀门，适用于具有低压（300磅/平方英寸）要求的简单开启或关闭系统。帕克的VQ系列拨动阀是在中等压力和温度应用中手动或气动开关控制的性能和值的正确组合。手动型采用一个拨动手柄，可在压力高达300 psig（21 bar）时快速动作。紧凑型双作用、常闭和常开气动阀门是600 psig（41 bar）压力下自动控制的理想选择。

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).
