XF61 Top guided Control Valve

Brief Description

XF61 top guided control valve is made up of multi-spring pneumatic diaphragm actuator and low flow resistance of single-seated control valve body, Multi-spring thin membrane actuators’  function is low height, light weight, simple equipment, Body flow of pneumatic single-seated control valve is in an s-shaped streamline, with the merits of compact, lightweight, less pressure drop loss, large capacity of valve, precise flow characteristic, easy maintenance, it can be used in harsh working conditions. Particularly applicable to allow the less leakage, both front and back valve pressure has no big difference and has a certain viscosity with a small amount of fibre medium.
