SPM® now offers a Status Indicator System as an option to be included in all new 3” and 4” Emergency Back Pressure & Unloading Relief Valves. The product operation concept is simple. At any given time when the valve piston lifts greater than 0.030”, the system will remotely indicate that the valve has opened. In the instance that the valve piston has dropped below 0.030” the system will then remotely indicate that the valve has closed.
The SPM® Status Indicator System can interface with existing customermanaged data monitoring and logging systems allowing for accurate control and trouble shooting of over pressure events on a frac site. The Data Van Interface directly integrates the Status Indicator System into the data van’s data acquisition system. A 200 ft weather resistant cable can be purchased separately for transferring data.
