Axial Flow Control Valves Manufacturers

Axial flow control valve consists of a valve body. It has a flow passage containing there in a cylinder and an annular sleeve both are held in position by a positioning sleeve. The annular sleeve has a wall member formed with a multi-pores means for providing a number of V-shaped or elongate ports for reducing noise and vibration of fluid flow. A push rod is axially movably disposed within the cylinder, having one end attached with a resiliently biasing means for resiliently engaging a valve piston axially displaceable within the cylinder and the annular sleeve for controlling fluid flow. The positioning sleeve is formed with a truncated conical valve seat to associate with the valve piston for sealingly occluding fluid flow. O-rings made of resiliently metallic or ceramic material are disposed on the valve piston and/or the push rod for sealing the axially movable elements, so that the valve can be used in a high-temperature environment.
