Hydraulic gate valve actuators MH70X & MHW70X
Built to operate reliably across a wide range of surface production applications, including remote and harsh environments
Overview
Our MH70X and MHW70X hydraulic gate valve actuators enable streamlined operations, time savings, and effective maintenance. Top-accessible piston seals and a simple actuator mounting arrangement support efficient operations and help minimize downtime, while rapid closing enables real-time flow control.
Various features that enable applicability to a wide range of requirements include flexible actuator orientation, access to our full selection of tools and accessories, compatibility with surface safety valves (SSVs), and wireline-cutting capabilities.
The actuators can be fitted with position-sensing limit switches and customized for compatibility with condition-based monitoring solutions per end-user requirements.

Applications
- Production trees on land or offshore wells, including in remote locations
- High-thrust applications: Large-bore and high-pressure valve deployments
Benefits
- Lower risk with nonpressurized actuator housing and fail-safe design that places the valve gate in the required position in the event of loss of hydraulic pressure
- Greater durability via corrosion-resistant materials
- Ease of maintenance enabled by top-accessible piston seals and unique actuator design
- Significant time savings due to simple actuator mounting arrangement
- Responsiveness to dynamic field conditions because of rapid closing time
- No special tooling requirements for spring replacement
Features
- Visual indication of valve position
- Full 360° rotation of pressure inlets and housing for precise alignment without stressed connections
- Stainless steel piston and T-seals for positive sealing and extended service
- Corrosion-resistant coating on all nonstainless steel components
- Drain plugs to help prevent water accumulation in actuator housing
- Digital capabilities: Position indication, pressure monitoring, and stem seal leakage monitoring
- Fixed drift adjustment via stainless steel spacers that are installed during manufacturing and provide a secondary means of setting the valve drift
- Drift setting unaffected by actuator removal
- Wireline-cutting option with enhanced spring load that provides the required cutting force
- Fail-safe design, compatible with SSVs
