Speed is non-negotiable in today's automation lines, and NTA hasn't overlooked it while chasing efficiency gains. The new valves are tuned for rapid, high-frequency cycling with near-instant response, ...

The cascading bypass system is perhaps the most common design for managing high-pressure steam in a combined-cycle plant. It is the hot reheat (HRH) bypass valve actuator that defines the valve’s ...

• Standard solenoid valves pose an ignition danger near hazardous materials. • Valves with pneumatic and magnetic actuators require no electricity, making them inherently safe in hazardous locations.

When we last spoke to the people at Microstaq Inc., maker of the silicon Ventillum microelectromechanical systems (MEMS) expansion valve IC, they were busy addressing the requirements of the HVAC ...

If you are interested in participating on ISA96, please contact ISA standards staff at +1 919-549-8411 or ISA Standards. The committee will develop standards and technical reports related to valve ...

The article will then look at valve types very briefly before focusing on digital positioners. It will examine the expectations that the user should have with regards to digital positioners, for ...
