The
Vatac Surface Safety valve is used in conjunction with an emergency shut down
system (ESD) which will be normally installed upstream of the choke manifold. The
valve is remotely operated either manually by push button or automatically triggered
by high/low pressure pilots. When a remote station is activated the emergency
shut down panel acts as a receiver for the air signal. The unit translates this
signal into a hydraulic response which bleeds the control line pressure off of
the actuator and closes the fail closed valve.
The
Vatac surface safety valve is used to provide fast response valve closure for
isolating the well in the event of an emergency, Vatac surface safety valves
are hydraulically actuated failsafe gate valves designed to close upon loss of
control line pressure. The Safety valve is used to quickly shut in the well in
the event of a leak to, overpressure or failure of any of the downstream
welltest equipment.
