PosiWell® DBB DIB-1 Valve: Innovating Valve Technology for Superior Performance
The PosiWell® DBB DIB-1 valve is designed by a team with over three decades of experience in servicing, repairing, and customizing conventional DBB valves. PosiWell® represents a breakthrough in valve technology.
Full Bore Design for Maximum Flow
PosiWell® full bore DBB DIB-1 expanding disc gate valve is an innovative design that ensures optimal flow efficiency vs traditional reduced-bore valves.
Built to Resist Corrosion and Chemical Degradation
One of the primary causes of failure in traditional DBB designs is corrosion and chemical degradation. PosiWell® DBB gate valves address these issues by utilizing stainless steel and RPTFE soft seat internal trims, with alternative materials available upon request. This robust construction not only extends the valve’s lifespan but also reduces the overall cost of ownership.
Experience Innovation and Reliability with PosiWell®
Combining innovative design with proven expertise, PosiWell® delivers reliable performance even in the most demanding environments. Its advanced features and durable construction make it the superior choice for industries seeking efficient and long-lasting double block and bleed valve solutions.

PosiMech – Multi-turn Valve Sensor Housing
THE PROBLEMS WITH TYPICAL SENSOR INSTALLATIONS
Mounting limit switches and sensors on linear multi-turn valves is a challenging task compared to quarter-turn valves. Often, the selection of the cheapest options leads to improper installations and unreliable performance. Common issues include:
Accidental Interference: Knocks, unauthorized tampering, and other interferences may disrupt signals, causing operational delays.
Pipeline Vibrations: These can cause false alarms, leading to potential asset damage and wasted resources.
Environmental Exposure: Strong winds, rain, and sun exposure can disorient and damage sensing mechanisms.
Compatibility Issues: Different designs are often needed for various brands of switches and sensors.
THE SOLUTION: PosiMech
PosiMech has been developed to provide peace of mind to our users. With PosiMech, you no longer need to worry about your limit switches and sensors failing because vital components are all encased within the PosiMech itself. Key features include:
Universal Compatibility: PosiMech is compatible with any switch or sensor. It was developed with modularity in mind, accommodating locking devices, gearboxes, key interlocking systems, and much more. Whatever your requirement, PosiMech can handle it.
Lightweight Construction: PosiMech offers an aluminum and stainless steel body option. For further customization, contact us.
Seamless Integration: Designed to be an integral part of the valve, PosiMech ensures a clean look and finish.
Future-Proof Design: As the valve age and require more turns over time, PosiMech allows for easy adjustments, ensuring continued performance.
