Applications: GV716 series are designed for use in systems where material are clean or non-corrosive gas. They are also available for single or multiple stages and standard or low profile bodies. They function by the up-down movement of gate forced by actuated gas. Well suited as shut-off device for pumps. Key features are easy and fast maintenance and virtually shock-free locking.
