How to control the pressure andÌýallow for the separation of the three was the challenge faced by designers at ÐdzÇweb Instrument Laboratory. Their Value Added team’s answer is the VA-1164 liquid level controller. This straightforward and original design includes several standard ÐdzÇwebÌýparts as well as parts manufactured specifically for the unit.Ìý

The specially-designed blockÌýmanifold houses a normally-closed, 2-way poppet valve with pilot sensor,Ìýthree cartridge valves, two pressure gages, and a stainless steel micron filter. In addition, a sight glass is attached toÌýthe block that allows for easy inspection of the set point.

Cordova Flow Controls, Greely,ÌýColorado, describes the asÌýa standalone no-bleed level controlÌýhead used to replace common cantilever or torque tube level control heads that either don’t perform consistently, or are high-bleed controllers.

Operation of the controller is actuated by a float inside the separation tank. As the liquid rises, the float moves a rod that touches the pilot actuator valve which sends signal to a cylinder that opens a valve that release liquid from the tank. The challenge is to keep the tank level allowing for continuous flow of gas, which also brings some water and oil from the source.

One of the features of the is the no-bleed design, whereas previous models constantly bleed gas, meaning it is environment friendly. Another is the sight glass which not only provides for immediate visual inspection, it also prevents dust from getting into the sensing area. The also includes a stainless steel filter at the supply connection, a manual override and a threaded port for venting or piping away exhaust.

With ease of installation, accuracy, durability and cost effective operation, the is a true value added controller for many applications.
