Unloading Equipment: Deactivator
CECO’s provides finger-style and plug-style deactivators.
Plug-Style Deactivator
CECO DurMAX™ deactivators can be supplied as a complete unit – ready to install on your compressor. By supervising the installation and training your station personnel, CECO assures the successful commissioning and operation of these custom-designed deactivators.
CECO DurMAX™ deactivators are fail-safe plug type with a balanced piston and open on loss of air pressure. We use two cast-iron rings on the plunger guide allowing the self-aligning plunger to seal properly. The plunger and guide are heat-treated 4140 steel and are hardened to provide long, trouble-free operation.
DurMAX™ deactivators conform to API specs and require only one air supply line. The covered sight glass gives a visual indication of closed or open position. The operating shaft is a high-strength alloy steel and noncorrosive. The operating cylinder has a noncorrosive wear surface for long service life.
Finger-Style Deactivator
CECO's DUR-FLEX® is the world's first long-lasting, low maintenance deactivator that can be used in valves requiring finger-style unloaders and operating up to 1,200 rpm. With small valve diameters, the only effective method of unloading suction valves is through the use of finger style unloaders. Until now, this method was fraught with problems. Finger and valve element breakages are extremely common.
The DUR-FLEX® finger-style deactivator compensates for varying pressure on the valve elements. It is more robust and reliable, eliminating premature failures inherent in older designs.The DUR-FLEX® design allows for the deactivation of valves without damaging them, and does it in a timely, efficient manner. This is accomplished with a unique patent pending self-dampening finger-style construction that eliminates the breakage of fingers or valve sealing elements. The CECO DUR-FLEX® deactivator unloads existing valves with excellent results.
