They control the filling of tanks and interrupt the supply when the maximum level is reached in the tank and prevents the overflow, we offer two basic types of valves: direct-acting float valves and piloted valves.
The direct acting float valves have a float that triggers the closing of the valve when the maximum level is reached: the upward force exerted on the arm by the float is transmitted to the piston, activating the closing.
In piloted valves with external controls, the closing is essentially produced by the hydraulic forces that are applied to the piston in the main valve; when the pilot placed inside the tank closes, it triggers the order of closing. These valves have the option of deferred opening, with two levels (one for closing and a lower one for opening). These valves may be installed in a chamber next to the tank and only require connecting the valve to the pilot with a ½”pipe.
