Quadax: Built For the Extreme

Designed for Extremes. Delivered by TRIVACO. Proven Zero Leak, Complete Isolation.

A valve is only as good as the engineering support behind it. Most “high-performance” solutions are treated as commodities, but in extreme heat, cryogenic cold, or high-pressure steam, a commodity valve is a liability. A single seat failure or a seized actuator doesn’t just stop a line—it stops your revenue.

At TRIVACO we engineer pathways to success. By combining the patented Quadax® Four-Offset design with our internal fabrication and automation expertise, we eliminate the mechanical friction that causes 90% of valve failures.

Why Standard Valves Fail Your System

If you are replacing seats every season or battling high-torque actuators, your current system is likely suffering from invisible design flaws:

The Elliptical Rubbing Fatigue
Most triple-offset valves (TOV) rely on an elliptical seat. This creates friction during the final degrees of closure, literally "rubbing" the seal away.
Thermal Seizing & "Ghost" Leaks
In LNG or high-heat service, metals expand and contract. Without a self-energized sealing strategy, standard valves either seize or lose their seal as the body "breathes."
High-Velocity Erosive Scouring
Wet steam or entrained solids act like liquid sandpaper. Once a standard graphite seal is scored, the media begins "wire-drawing" through the seat, making a bubble-tight shutoff impossible.
The Shaft Deflection Crisis
Under Class 900# or 1500# pressure, discs can "bow" slightly. This microscopic deflection pulls the seal out of alignment, causing packing leaks and seat failures.

The TRIVACO Solution: Built for the Extreme

TRIVACO provides a monolithic approach to flow control. We leverage the Quadax® 4-Offset engine to solve the problems that standard 3-offset valves can’t touch.

Patented Quadax® Four-Offset Geometry

The 4th offset transforms the seal movement into a perfectly circular path.

Advanced Material & Seal Science

We match the seal metallurgy to your process chemistry in-house:

Turnkey Automation & Fabrication

We don’t just ship a valve in a box. Our Hebron, KY facility provides custom mounting, precision-machined brackets, and expert actuation sensing to ensure your Quadax valve operates at peak efficiency.

The TRIVACO Advantage

Elliptical Friction: Seal "rubs," leading to seat deformation.
Thermal Seizing: Inflexible seals fail during temperature shifts.
High Maintenance: Re-sealing required every few seasons.
Higher Leak Risk: Vulnerable to particulate and steam scoring.

Circular Seating: 100% friction-free for infinite cycles.
Inconel O-Rings: Self-energized rings that adapt to T.
Extended Lifecycle: Designed to outlast the piping itself.
Zero Leakage: Proven bubble-tight shutoff in LNG & Steam.
