Description Our ROV Operated DCV Valve is a field pro-ven component used in subsea systems all over the world. Available in a number of configurations.

The Envirex Panel Mounted ROV Operated Rot-ary Control Valve are designed to meet the requ-irements for use in in the most demanidng harsh subsea environments. Our standard range of rotary control valves is available at pressure rationgs up to 10,000PSI (690Bar) and water depths to 3000 meters (10.000Ft).

Envirex can supply standard design or customer specified variations of ROV actuator interfaces

Features Exess torque not transferred to valve stem Stainless Steel Construction Wide Range of fluid compatibility Rated to 3000MSW Service and user friendly Custom design available Less leakage point Common pressure and return port

Typical Applications ROV Control Panels BOP Intervention Panels Subsea Control System Chemical Injection Systems Subsea Tooling

DESIGNEDfor demanding subsea environments

ROV Operated DCV - Manifold Mounted

Description

The Envirex Valve Manifolds are specially designed for integration into ROV panels, systems and tooling.

The Envirex DCV Manifolds can be set up with different valve configurations according to customer require-ments. The manifolds can also be fitted with a separate supply isolation valve to isolate each manifold from the main hydraulic supply system.

The manifolds are used in many different settings and is a perfect choice for ROV Operated control systems and fail/safe override functions.

By using these manifolds the system will have less leakage points and get a common supply and retur line for the directional control valves. Installation and system integration will take less time and the total costs associated to this will be reduced.
