ZQP type stop valve

Pneumatic Stop Valve | Electric Stop Valve

ZQP Type Stop Valve Introduction

ZQP stop valve has a simple structure, easy operation, small volume, lightweight, good seal, large flow, reliability using and so on. The disk can use a single action or sleeve to adopt stop needs under different pressure drops. It can choose a big push pneumatic piston actuator or electric actuator.
