Maria Valve
1 / 5
The Safety Valve is a critical shutdown device integrated into wellhead and surface flow control systems. When activated by pneumatic, hydraulic, or electric actuators, it ensures immediate well isolation in emergencies—such as detected hydrocarbon leaks, overpressure events, or fire—to safeguard personnel, equipment, and the environment.
Based on a robust gate-valve architecture, the valve features a high-performance actuator engineered for reliable operation under extreme pressure and extended service life. It provides fail-safe closure, with actuation times typically between 4 to 8 seconds. The assembly incorporates a mechanical locking mechanism and is designed with fire-safe construction to maintain sealing integrity under high-temperature conditions.
The valve is suitable for installation as a master or wing valve on Christmas trees and surface production manifolds. Its operation is managed through a dedicated control panel, which allows for local or remote activation, status monitoring, and integration into broader safety instrumented systems (SIS) or emergency shutdown (ESD) protocols.
