Level Controls

LC10 Level Controls are rugged, field configurable, displacer-operated, liquid level controllers. Ideal applications include scrubbers, separators, and heater treaters. Their industry-proven force balance design allows for control of gas/liquid as well as liquid/liquid interfaces. The LC10 can be mounted on the left or right hand side and can be set up for direct or reverse acting. Both the mounting and action are field reversible. Models are available with an easily replaceable snap or throttling pilot for pneumatic control. The snap pilot is available with a soft seat option that meets 40 CFR Part 60, Subpart 0000. SPDT and DPDT switches are available for electric control.

The LC25 Electric Level Control is a low-pressure, float operated, liquid level switch. With a working pressure of up to 200 psi, the LC25 features a rugged aluminum housing containing a SPDT switch that can be wired to either make or break contact when the liquid level rises or falls.

The LC40 Liquid Level Switch is a head pressure operated level controller meant for use on atmospheric storage vessels. The LC40 can be used as an easy to read, real-time visual indicator showing the height of the liquid in a vessel or tank. The switch option includes a SPDT electric switch that can be set to trigger at different heights for rising and falling level. The LC40 has adjustment knobs for zero offset as well as for span which is used to set it for different specific gravity fluids.

The LC50 Snap Level Control is a float operated liquid level control. With a maximum working pressure of 500 psi, it is a great choice for low to medium pressure applications. Its adjustable range allows it to be used as either a hi/low alarm or a traditional level controller. The LC50 contains a replaceable 3-way block and bleed pilot featuring a soft seat for a bubble tight shutoff. It is available in 2” threaded, 4” or 5” union, and 4” grooved connection sizes. Two stainless steel float sizes are available with other sizes and arm lengths by request. For sour service a NACE option is available.

The LC60 Liquid Level Control is a float operated liquid level control with a wide adjustable span. The high and low trigger points are independently adjustable and can be easily accessed by simply removing the cover. It has a maximum working pressure of 500 psi, making it a great choice for low to medium pressure applications. The LC60 contains a replaceable 3-way block and bleed pilot featuring a soft seat for a bubble tight shutoff. It is available in 4” flanged and grooved connection sizes. Two stainless steel float sizes are available with other sizes and arm lengths by request. For sour service a NACE option is available.

The LC70 Level Control, now available with patent pending Gator Technology, is a float operated liquid level control device sometimes referred to as a “trunnion” or a “float nose”. The LC70 utilizes a large float, linkage rod and levers to mechanically operate a dump valve via rotational connections. The Gator is a spline mechanism that replaces existing “D” or keyed rotational connections that quickly wear out through normal use. The spline design eliminates slippage/slack, providing greater accuracy and precision. The LC70 is available in 2 different body styles: 8” Union and Bolted. The levers can easily be changed from the left to right to match the dump valve mount.
