The OVAL 45B10 Valve Open-Shut Indicator 364.7CC N2-22 is a specialized marine automation device designed for accurate valve position monitoring and feedback in hazardous marine environments. Unlike a standard mechanical valve indicator, this equipment combines local visual indication with electrical signal transmission, allowing real-time monitoring of valve positions from cargo control rooms, engine control rooms, and integrated automation systems.
This type of valve position indicator is widely installed onboard oil tankers, chemical tankers, LNG carriers, LPG carriers, offshore platforms, and specialized cargo vessels where safe valve operation is critical. The unit provides reliable feedback regarding whether a valve is fully open, fully closed, or operating at an intermediate position.
The equipment visible in the supplied photographs is an intrinsically safe model designed for hazardous cargo environments where flammable gases or vapors may be present. The presence of a 4–20mA output signal allows the indicator to communicate valve position information directly to vessel automation and cargo monitoring systems.
For ship operators, accurate valve position monitoring improves safety, minimizes operational errors, supports cargo handling procedures, and helps prevent costly incidents during transfer operations.
SM MARINE SERVICE™ supplies OVAL valve indicators, marine automation equipment, spare parts, repair services, calibration support, and technical solutions for customers worldwide.
The actual stock units supplied by SM MARINE SERVICE™ are shown below and represent genuine OVAL 45B10 Valve Open-Shut Indicators currently available for supply.
The OVAL 45B10 Valve Open-Shut Indicator belongs to a class of marine valve monitoring devices used throughout tanker automation systems. These indicators are installed directly on valve actuators or valve operating mechanisms and continuously display valve position both locally and remotely.
Based on the equipment markings visible in the supplied photographs, the unit features:
The unit's design makes it particularly suitable for hazardous cargo areas where conventional electrical devices may not be permitted.
During cargo loading, unloading, stripping, tank cleaning, ballast transfer, and fuel transfer operations, officers and engineers depend on accurate valve position information. The OVAL 45B10 system helps eliminate uncertainty by providing continuous valve feedback.
SM MARINE SERVICE™ maintains stock and sourcing capability for OVAL valve position indicators and related tanker automation equipment.
The OVAL 45B10 is designed for operation in hazardous marine environments. Intrinsically safe construction limits electrical energy levels and reduces ignition risks in potentially explosive atmospheres.
The analog dial allows personnel to instantly verify valve status directly at the installation point. Open and shut positions can be confirmed without requiring access to a remote monitoring station.
The device provides electrical feedback to cargo control systems and integrated automation systems. This allows remote supervision of valve operations from centralized control locations.
The use of industry-standard 4–20mA output signals ensures compatibility with a wide range of marine automation systems and cargo monitoring platforms.
The rugged housing is designed to withstand vibration, humidity, temperature fluctuations, and harsh marine environments commonly encountered onboard vessels.
The indicator plays an important role during cargo transfer operations, ballast management, fuel transfer, and emergency shutdown procedures.
SM MARINE SERVICE™ provides technical support, spare parts, and repair services for these systems worldwide.
