403-11 Pneumatically Operated Remote Control Valve – Freshwater and Seawater Ser

The Cla-Val 403-11 Remote Control Valve is used where “on-off” control is required. Pressure signals from a remote control “open or close” a small auxiliary valve installed on the main valve cover, which in turn opens or closes the main valve. Only the small amount of fluid in the auxiliary valve cover must pass through the remote control pilot in order to fully open or close the larger main valve.
