Inline Control Valve, Air-to-Close, 3" FNPT, Cla-Val Model 7100, 81665C

Product Description

The Cla-Val 7100 Inline Control Valve (81665C) is a dependable, heavy-duty solution designed for controlled fluid flow in demanding applications. Featuring a 3" FNPT connection, this valve is ideal for water trucks, industrial systems, and equipment requiring reliable inline flow control.

This model utilizes an air-to-close (normally open) operation, allowing the valve to remain open until air pressure is applied to close it. This makes it especially useful in systems where fail-safe flow or controlled shutoff is required. Built on the proven Cla-Val 7100 platform, it delivers consistent performance, tight sealing, and long service life.

With its rugged construction and straightforward design, the 81665C valve performs reliably in harsh environments while minimizing maintenance and downtime.
