Safety Equipment

For more than 70 years, OCV Control Valves has manufactured and supplied hydraulically operated, diaphragm actuated, automatic control valves.  Our high quality control valves can be found throughout the world – from municipal water systems in the US, to Russian oil refineries, to irrigation systems in Europe.

For emergency shutdown in case of fire and high temperature atmosphere.

The most advanced terminal overfill prevention and ground verification system available.

• The only control system that offers overfill prevention, static grounding, and vehicle identification all-in-one unit
• The ultimate in terminal loading safety with a patented design that continuously monitors the relay contacts—for petroleum and chemical loading racks
• Incorporates Dynacheck® Dynamic Self Checking® circuitry for overfill prevention, ensuring that every critical component is automatically and continuously checked for maximum loading safety
  • This includes the control unit, wiring, and sensor circuitry, and should a fault be detected, it signals a loading shutdown to prevent product from overfilling
• Over 15 years of proven performance in the field—the number one choice worldwide

Multiple-Point, Optic-Sensing Overfill Prevention Control Unit

• Interfaces with five-wire optic sensors
• Used, typically for bottom and top-loading of tank vehicles
• Mounted at the loading rack/gantry and connects to the vehicle via the Scully plug and cable assembly (sold separately).
• Features Dynacheck® circuitry for automatic and continuous self-checking of all system components
• For vehicle ground/earth verification options, consult Scully for information on the Groundhog Self-Proving Grounding System.

Vehicle Static Ground Verification System

• Self-proving technology based on Scully’s original patented design
• Can operate in conjunction with your Scully Overfill Prevention System (ST-35® or ST-15) or as an independent ground verification unit
• Immediately shuts down the loading operation if proper static grounding is not detected

Safe, reliable, high- and low-level warning and spill prevention system for storage tanks

• The system incorporates Dynamic Self-Checking® circuitry which monitors the controller, wiring, connections, and sensors for faults 30 times per second for maximum safety

• Sounds an audible alarm and/or controls pumps and valves for automatic shutdown when the sensors detect liquid or a fault in the system

• As a high level warning and emergency shut-down system, it operates independently from your gauging system to ensure that inventory inaccuracies do not compromise the safety of your operation.

• The sensors wired to a control unit provide high level detection for a wide variety of petroleum and chemical products

A-T Controls is a global leader in the design, manufacturing and sale of manual & automated process valves for all types of industries.

OCV offers a wide variety of waterworks control valve designs, engineered to meet the entire spectrum of water utility system requirements. By controlling pressure, rate of flow, and surge and pump control, engineers and specifiers rely on our valves to help improve the efficiency of both supply and distribution. OCV also specializes in altitude control valves to service elevated water tanks and digital control valves to interface with high-level SCADA systems.
