Subsea MDF Kit Valve Activator for Offshore Oil and Gas Production with Pressure-Compensated Design

Subsea MDF Kit Valve Activator for Offshore Oil and Gas Production with Pressure-Compensated Design

Product Description:
The Subsea MDF Kit Valve Activator is a feat of marine engineering, designed to perform critical valve functions in the deep-sea environment. Deployed on subsea production trees, manifolds, and pipelines, this robust actuator must withstand immense hydrostatic pressure, corrosive seawater, and total isolation for extended periods. Its key feature is a pressure-compensated design, which equalizes the internal pressure with the external ocean pressure, preventing the housing from being crushed and ensuring the internal mechanics can operate smoothly at any depth. Constructed from high-strength, corrosion-resistant alloys like Duplex or Super Duplex stainless steel, it offers exceptional resistance to both seawater and sour gas (H2S). The actuator is filled with a specialized dielectric fluid that provides lubrication and corrosion protection while acting as the compensating medium. Every component is tested to the highest standards to guarantee absolute reliability, as retrieval for repair is phenomenally expensive. The MDF Kit Valve Activator is the workhorse of the subsea industry, enabling the remote control of wells, the management of production flows, and the execution of emergency shutdowns on the ocean floor, making deep-water oil and gas extraction possible and safe.

Bullet Points:

• Built for the extreme pressures of offshore oil and gas production.

• Pressure-compensated design ensures functionality at great depths.

• Constructed from corrosion-resistant marine-grade alloys (Duplex Stainless Steel).

• Provides reliable valve control for subsea Christmas trees and manifolds.

• Equipped with ROV (Remotely Operated Vehicle) interfaces for backup operation.

Specific Application Scenario
This activator is mounted on a subsea Christmas tree one mile below the ocean surface, controlling the main production wing valve that regulates the flow of oil and gas from the wellbore to the pipeline.

Factory Production Floor
Production involves ultra-precise machining and welding in a certified facility. Every housing is subjected to hydrostatic pressure tests far exceeding its rated depth. The final assembly and fluid filling occur in a clean room, and each unit undergoes a full-function test in a hyperbaric chamber.

Packing and Transportation
The activator is coated in a temporary protective coating, and all ports are sealed with multiple layers of protective caps. It is then bolted to a custom shipping skid and crated for secure transport to the dock for load-out to an offshore vessel.

FAQ
1. What is the maximum depth rating for this subsea actuator?
Our standard subsea actuator models are rated for water depths up to 3,000 meters (10,000 feet), with custom designs available for even greater depths.

2. How does the pressure-compensated design work?
The pressure-compensated design uses a flexible membrane or bladder system that allows the internal dielectric fluid to equalize with the external sea pressure, nullifying the crushing force on the housing.

3. Why are marine-grade alloys like Duplex Stainless Steel used?
Marine-grade alloys provide the necessary yield strength to withstand high pressure while offering superior resistance to pitting and stress corrosion cracking in chloride-rich seawater, which is critical for offshore oil and gas production.

4. What are the primary and secondary control methods?
Primary control is typically via an umbilical from the surface. Secondary control is through an ROV interface, allowing a submersible to manually operate the valve if the primary system fails.

5. What is the expected service life in a subsea environment?
These actuators are designed for a service life of 25+ years with minimal maintenance, reflecting the immense cost and difficulty of subsea intervention.

Future industry manufacturing complex spans an area of nearly 7,000 square meters. It incorporates six high-speed aerosol valve production lines and more than 30 special valve production lines.

Each year, Future industry aerosol can produce up to one billion aerosol valves. Our main products are air freshener aerosol valve, insecticide spray aerosol valve, butane gas aerosol valve, carburetor cleaner aerosol valve, ribbon spray aerosol valve, snow spray aerosol valve,paint spray aerosol valve, fluid spray aerosol valve, portable stove gas aerosol valve, 360 degree aerosol valve, powder spray aerosol vave. Also we have expanded the export market of aerosol metering valves, aerosol caps and aerosol cans.We have also built five standardized workshops to conduct different operations in order to meet the requirements of various customers to ensure we always meet production demands and timelines.

Production of the valve mounting cups is carried out in this workshop. We use a high-speed automatic stamping machine to transform high-quality steel plates into valve mounting cups. Due to the high degree of its automation, this equipment can help to reduce labor costs and increase production efficiency significantly.

In addition, we utilize an efficient machine that can automatically press an outer rubber ring into a valve mounting cup in order to provide superior sealing performance in the process of final assembly.

This workshop contains over 20 injection molding machines and three injection molding lines. Among them, our injection molding machines are used to produce a variety of accessories such as valve stems, valve chambers, actuators, and spray caps, etc.

Due to efficient automation, we require a very small number of staff to run these more than 20 injection molders. During the production process, our quality control inspectors are responsible for sampling and testing every batch of accessories. Additionally, our injection molding line has the capability to produce various sizes of dip tubes in automatic mode.

This workshop is used to assemble all kinds of accessories. It is equipped with automated assembly equipment to greatly increase production efficiency and provide our customers with enhanced profits.

After assembly is completed, our valves will be automatically counted and packed. We are proud to say we are one of the few companies in the industry that possess advanced abilities in product research and development. Every new product needs an innovative mold. For this reason we utilize high-precision wire cutting machines and machine tools that can form our molds into exquisite shapes.

We possess a wide range of technical production and R & D expertise
