The ESD and SSV valves are an integrated electro-hydraulic flow power unit designed to operate hydraulic actuators for flowline PwrESD surface safety valves. The compact system design provides a minimal added footprint to the SSV while providing local and remote open and close functions. to the valve. PwrESD also minimizes the number of hydraulic fittings and connections to limit potential leak points.
The system comes with a 1/4 to 1 HP (0.18 to 0.75 kW) 24 VDC or AC motor for remote opening and holding in the fully open position. It also includes a backup hydraulic hand pump. A low power 24 VDC solenoid valve (0.85 W) is used to maintain pressure in the low pressure circuit to control the opening and closing operation of the SSV. The system can house pressure transmitters, limit switches, position transmitters, and hydraulic fluid level switches in an explosion-proof electrical enclosure for wiring to a Stream-Flo Intelligent Valve Controller (IVC), Distributed Control System (DCS), or Integrated Programmable Logic Controller (PLC). PLC) to prepare.
Features and benefits:
Compact Design – The system is designed to be completely self-contained for ease of installation on new or existing SSVs.
- Local and remote operations.
- Independent emergency shutdown (ESD) capability through a solenoid valve, manual shut-off valve (ESD),
and/or fusible element or other means.
-Multiple power options for electric motors with CSA/UL and/or ATEX/IECEx certifications.
- Multiple displacement options for hydraulic pump drive motor for different valve opening speed requirements.
- Operating hydraulic pressure up to 3300 psi (22753 kilopascals).
Supply of valves and oil and gas well accessories with Stream Flo brands:
After drilling and completing the well, equipment is installed on the well to control and exploit the well, according to its anticipated position and needs, and well valves are among these tools. The most important purpose of using this valve is to provide a place for suspension and pressure seals for casing strings that move from the bottom of the well to the surface pressure control equipment.
Well valves cover all the requirements of the A6 API standard and include a wide range of sizes, material types, quality levels and pressure classes.
Surface pressure control is performed by a wellhead valve installed at the top of the well and equipped with isolation valves and choke equipment to control the flow of well fluids during production.
The components of Oil and gas well valve are three main valves:
1. SSSV is a safety valve that is located at a depth of about 50 meters, and it is impossible to access it under normal conditions, and if it is closed for some reason, special equipment is needed for repair.
2. Another valve or another part of the Master well valves.
3. The third valve is Wing, and Stone Trap is placed at the outlet of this valve, the outlet of which is connected to the HIPPS system.
In the middle part of the well valves, there are three valves, each of which is connected to one of the shells of the well equipment and is connected to each of these valves to show the pressure of the manometer shell.
A display is installed on the right side of the well valves to display the well pressure. The Wing and Master valves are located on the surface, and to close the well, the Master, Wing and SSSV valves are closed respectively. In this way, the valves are closed from the top, and to open it, you have to do the opposite.
