The Cla-Val 81663H Model 7100 is a 2-inch air-to-close inline control valve designed for remote pneumatic control of water flow in water-truck and industrial plumbing systems. Its diaphragm-operated design provides reliable shutoff while allowing the valve to open fully when control air is released.
This 2-inch FNPT configuration is well suited for water-truck spray systems, discharge plumbing, dust-control equipment, and other applications that require remotely actuated water flow control. The Cla-Val 7100 design uses a replaceable seat and serviceable internal components to simplify maintenance and reduce downtime.
