The Status Indicator System for Emergency Back
Pressure & Unloading Relief Valves allows for remote indication
and data logging while creating a safe environment for technicians.
This optional feature to Weir SPM's existing Nitrogen Relief Valve
offering notifies the operator immediately and safely that an event
has occurred by providing a remote indication and an electronic
record of an over pressure event.

Weir SPM is offering 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 Weir SPM Status Indicator System can interface with existing
customer-managed 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. Integrating
with the Data Van Interface benefits the user by featuring an
easily visible status notification during fraccing operations and
during overpressure events, allowing for an electronic record of
the event including reaction time of the valve relative to the over
pressure event. A 200 ft weather resistant cable can be purchased
separately for transferring data. Contact Weir SPM's Flow
Engineering team for more detailed information about interfacing
data.
Benefits of the Status Indicator System:
• Allows an electronic record that the valve
has opened
• Allows electronic data logging of the
reaction time of the relief valve, relative to the overpressure
event
• Creates a safer environment for the
technician, by allowing remote indication when the valve has
opened
