4-Way Bi-Level Vertical Float #66

This 4-Way, adjustable, last position bi-level vertical float, is actuated by the float sliding along the rod assembly to either pull it down or float it up, switching the float pilot position. When the float is between the adjustable high and low level stoppers, the main valve remains in its last position. The float pilot … Continued

Pitot Tube

When a pitot tube is used as an integral part of a flow control valve control circuit, it provides the differential pressure (ΔP) to power the flow control pilot. A pitot tube flow sensor is recommended for applications where low head loss is essential and required flow is relatively high. Due to its low ΔP … Continued

2-Way Modulating Vertical Float

This adjustable 2-Way Modulating Vertical Float is actuated by the “locked in place” float either pulling the float assembly rod down or floating it up. This float can be used to control reservoir filling or emptying:  When used as a filling level control pilot, it throttles closed as level rises towards set point.  When used … Continued

Orifice Assembly

When an orifice plate assembly is used as an integral part of a flow-control valve control circuit, it provides the differential pressure (ΔP) to power the flow control pilot. The opening and closing of the pilot causes the flowcontrol valve to throttle accordingly. Total head-loss across the valve is reduced by locating sensing ports close … Continued
