Cowan Dynamics: SIL 3 Certified Linear Hydraulic & Pneumatic Actuators

Cowan eNews Release image 1.27.16Cowan Dynamics announces the availability of linear hydraulic and pneumatic actuators with up to a SIL 3 safety rating. The SIL 3 capable rating is designed to provide our customers reliable actuation solutions in critical applications without compromising their Safety Instrumented Systems (SIS - compliant with IEC 61511/ISA 84).

The SIL 3 capable rating was achieved by certifying the products to IEC 61508 and was obtained from Exida Certification Services after passing rigorous Failure Mode Effects Diagnostic Analysis (FMEDA).

Cowan Dynamics’ SIL 3 capable products include:

A Series – Double-Acting Pneumatic Valve Actuator

AS Series – Spring-Return Pneumatic Valve Actuator

AT Series – Pneumatic Control Valve Actuator

A2A Series – Pneumatic Pressure Booster

ML Series – Hydraulic Valve Actuator

MS Series – Spring-Return Hydraulic Valve Actuator

Products certified to SIL3 capability are, on request, supplied with copies of the Exida certification, which contains all the information that engineers and designers need to calculate the safety integrity level of their complete system, based on its component parts.

Moog: Actuator for Customized, Critical Service

Spectork Valve Moog smallMoog Inc. has released its Moog Spec-Tork custom pneumatic and hydraulic rotary actuators to meet OEM torque and speed specifications. Spec-Tork actuators satisfy special customer requirements that vary from the capabilities of Moog’s standard actuators. For example, the Spec-Tork can meet applications that might include: rotations of less than 90°; special cushions for high speed requirements, electro-hydraulic actuators and systems, integral valving and special mounting flanges. Moog’s engineers can also customize its Spec-Tork actuators for applications including lift and turn, dampers, and fluid power service.

The Spec-Tork can provide millions of cycles of continuous service and achieve 90-degree rotation in less than five seconds, for catalytic cracking units, pipe line valves, and electric valve actuation and R&P valve actuation in processing plants. For natural gas processing plants, the fireproof-enclosed Spec-Tork can produce 1,440,000 pound-inches of torque and have a hydraulic pressure rating of 3,000 psi. The Spec-Tork’s end-of-stroke design reduces the shock to both the actuator and the valve it controls, which extends service life.  

AUMA: Fail Safe Actuator

pic AUMA FQMFor applications with significant hazard potential in the oil & gas sector and other industrial markets, fail safe actuators are required. These specialist devices automatically open and close valves in the event of emergency, even with disrupted power supply. Meeting these challenging market requirements, a new AUMA FQM fail safe unit offers an innovative mechanical actuator solution.

Incorporating a patent pending constant force spring motor, the new AUMA fail safe unit mechanically provides the required torque in the event of an emergency. While conventional springs lose 80% of their torque across valve travel, the AUMA solution provides virtually constant torque. Additionally, an overriding gear arrangement ensures that the spring does not move during standard operation. Both these factors contribute to enabling selection of significantly smaller actuator solutions. Premature spring fatigue and excessive torques at the valve are also avoided.
