Stream-Flo’s Crown Hydraulic Self-Contained, Spring-Fail Closed Emergency Shutdown (ESD) System is used for the automatic closing of gate valves on wellheads and flow lines under emergency conditions. The system consists of a hydraulic actuator, a manual hydraulic pump and control assembly, and a reverse-acting gate valve. The system can be tripped by several means, the most common means by a pressure pilot which trips the system when it senses pressure fluctuations outside of the specified control range. Also remotely by the use of solenoids and position switches
Stream-Flo ESD models can be equipped with single or double-acting hydraulic or pneumatic actuators with manual override and fail-safe closed or open systems.
Stream-Flo’s Crown gate and check valve products feature a full bore/thru-conduit design, in-line reparability and protected long-life seats. The gate valves are designed for all types of applications.
Stream-flo wellheads, gate valves, check valves, valve automation and control are proven around the world in the most demanding operating environments
Stream-Flo Crown Self-Contained Hydraulic ESD / SSV actuation system mounted as a master valve shutdown system. It is being powered and controlled by remotely located Crown Pump Control Unit and tripped by an integral Crown High / Low Pressure Sensing Pilot and RTU / SCADA. It is equipped with position indicating limit switches.
Self-Contained Hydraulic: Emergency shutdown systems & Surface safety Valves
Stream-Flo’s Crown self-contained hydraulic valve actuation systems are used for the automatic closing of gate valves on wellheads and flow lines under emergency conditions, such as emergency shutdown systems and surface safety valves. The system consists of a hydraulic actuator, a manual hydraulic pump and control assembly, a reverse-acting gate valve, and some form of tripping control(s).
Hydraulic Valve Actuation
Stream-Flo’s Crown hydraulic actuated valves are used for the automatic closing of gate valves on wellheads and flow lines under emergency conditions. The system consists of a hydraulic actuator and a reverse-acting gate valve.
Proven in extreme conditions around the world, Crown hydraulic actuated valves are API 6A certified and SIL 3 capable to provide reliable protection of personnel, facilities, resources, and the environment.
Config2 Integrated Systems
Combining the industry-leading technologies from Stream-Flo and Master Flo Valve in a factory assembled and tested system provides substantial cost savings to assemble and install on-site, faster installation, and a smaller footprint. The Stream-Flo Surface Safety Valve (SSV) provides reliable automatic shutdown in the event of abnormal pressure fluctuations in the flow line due to fire, ruptured line, surface equipment failures/faults, damaged wellheads or other causes. Master Flo’s choke/control valve provides effective flow control at all flow rates, along with superior resistance to sand erosion and body or outlet port erosion
The Config2 consists of an actuated gate valve assembly, choke/control valve, access tee, pump control unit, pilot, isolation valve, needle valve and pressure gauge. Trip control devices such as a solenoid can be added. The actuated gate valve is on the upstream end, the access tee on the downstream end, and the choke/control valve is located between the two.
Wellhead Control Panels
Stream-Flo is able to provide self-contained hydraulic and electro-hydraulic wellhead control panels for use with any combinations of flowline and/or wellhead-located surface actuated valves and/or surface controlled subsurface safety valves on your wellsite.
Stream-Flo’s Wellhead Control Panels can be provided as industry standard or as custom built designs to meet any of your actuated valve, instrumentation, or material needs.
As well, Stream-Flo’s Wellhead Control Panels are provided with many unique features to ensure that the Panel and its hydraulic control circuits are never contaminated by either the atmosphere at the site or by the produced fluids that the system is controlling.
Stream-Flo's wellhead systems provide solutions for surface production and injection applications, and are proven around world in all service types
Check and gate valves
Stream-Flo’s check valves are proven in the most demanding environments to provide safe, reliable pipeline operation.
