Profile: Tectrol USA, Inc. specializes in manufacturing a long nose gas choke, high pressure control valves, liquid level controls and pressere control equipments. Our model 4-liquid level controller uses a sensing rod with an attached displacer on the end. With the rising of the fluid the static lift force allows the actuator pad to move closer to the nozzle, diverting the supply pressure to a diaphragm operated motor valve. As the fluid drains, the level drops and the pad moves away from the nozzle, resulting in the relief of the supply pressure and the diaphragm operated motor valve closes. Snap valve is the miniature valves being offered for industrial application. It features a 1/16 inch orifice, with a working pressure of 100 PSI, encased in a standard anodized housing.
