Rotork IQ3 Environmental Protection

August 29, 2014

Rotork IQ3 controls

Rotork's IQ3 Actuator's environmental protection and cable-less data communication includes the use of bidirectional handheld wireless technology as well as the non-intrusive local controls. The cut-out photo shows how the local control is mounted without the control or any wiring penetrating the case. Through use of magnetic hall-effect sensors the local controls keep the interior of the IQ3 fully isolated from the environment. Rotork IQ3 Actuators

Rotork IQ3 Enhanced Sealing

August 23, 2014

Rotork IQ3 cutaway

The Rotork IQ3 cutaway photo illustrates some of the enhanced sealing for outstanding environmental protection. The terminal compartment is double-sealed to protect the actuator even while cabling. Thrust bases are separable across all ranges, the IQ3 gives extremely reliable valve position sensing (independent of voltage and temperature variations), and the casing coatings provide improved corrosion protection.

Rotork Fireproofing

August 16, 2014

Rotork Fireproofing

Rotork offers a wide range of options for fireproofing actuators. The semi-rigid enclosure offers fire protection of up to 30 minutes and 2,000F for all actuators including the IQ3. The flexible enclosure offers similar fire protection as well being capable of being tailor-fitted to also contain gearboxes. The patented System-E fireproofing coating is molded to the actuator itself and reflects heat back into the fire. Rotork IQ3 Actuators

Bray Series 22/23 Butterfly Valve

August 14, 2014

Bray 22/23 Butterfly Valve

Bray Series 22/23 Butterfly Valves offer high CV values, bubble-tight shut-off, and a long service life. The reinforced PTFE gaskets between the body halves eliminate external contamination and potential leak paths. Secondary seal capsules apply upward and downward pressure on the seat and disc surfaces to isolate the stem and valve body from the line's media. Accessories include a tapped leak detector port in the body neck below the stem seal. Bray Valves

Detcon GD1 Laser Open Path H2S Gas Detector

August 12, 2014

Detcon GD1 Laser Open Path H2S Gas Detector

The Detcon GD1 Laser Open Path H2S Gas Detector uses a tunable laser diode that eliminates environmental effects (fog, rain, and sun) to enable superior stability and the fastest possible response time while requiring no recalibration. Multiple standard detectors can be replaced with the GD1 to monitor the same hazards. The electrical classification is Ex II 2 G Ex e IIC T4/T5/T6. Detcon Gas Detectors
