Multistage Minimum Flow Control Valve

Product Description

INTRODUCTION

ZHD multistage minimum flow control valve cage control valve used multilevel cage symmetric sleeve control valve. It complete control medium velocitywithin valve, and greatly reduced noise made by high pressure gas or steam within valve, stabile multistage pressure reducing effective prevent liquid cavitation, so it’s the stable control valve used in high-pressure medium performance,customers can also select multi-spring diaphragm mechanism or pneumatic actuators, etc.
