Why Choose TRIVACO’s MARC-Certified Service?

TRIVACO x Masonelian Valve Services

Emergency & Planned Maintenance

When equipment fails or planned shutdowns approach, we’re ready. Our valve repair services restore your equipment to “like new” condition using factory-certified processes. We can bring our expertise and equipment directly to your facility for onsite repairs, or help you plan shutdowns strategically to minimize outage time. When issues arise, our troubleshooting expertise identifies root causes and implements lasting solutions.

Performance Optimization

We provide commissioning and startup support to ensure new equipment performs to specification from day one. As your operational demands change, our retrofit and upgrade services modernize equipment to meet new environmental and performance requirements. Re-instrumentation services can unlock efficiency improvements that deliver measurable cost savings, while our predictive maintenance tools like EVT-Pro monitor valve health to catch issues before they cause failures.

Asset Management & Intelligence

Control Valve Repair & Process Loop Optimization

Control valves are precision instruments. When a valve develops stiction — friction-induced hesitation in the actuator or packing — it introduces dead band into your control loop. The result is process oscillation, setpoint overshoot, and product variability that your DCS can’t fully compensate for.

We diagnose and correct the failure modes that generic shops miss:

Stiction &
Hysteresis

Stiction in the valve stem creates the classic stick-slip response that drives loop cycling. Hysteresis — the lag between signal and response — directly widens control band. We evaluate both through stroke testing and actuator bench diagnostics, then correct at the mechanical source rather than masking it with tuning.

Cavitation &
Flash Damage

Liquid service valves operating near vapor pressure are vulnerable to cavitation, the collapse of vapor bubbles that erodes trim, destroys seat surfaces, and generates noise and vibration that shortens valve life. We assess trim geometry, material compatibility, and pressure recovery characteristics to determine whether repair, trim replacement, or application re-matching is the right call.

Seat Tightness
Testing

Seat leakage testing is performed in accordance with, or exceeding, the seat class ratings specified by each manufacturer. If your application requires a specific shutoff class, we verify it and document it for your records.

Application Matching Review

If your control valve is the right model in the wrong application, the wrong Cv, the wrong trim style for the fluid, or the wrong actuator sizing, we flag it. You should know before the valve goes back in the pipe.

Our Canton, GA shop is our designated Masoneilan Authorized Repair Center (MARC) for control valve service. All control valve work is backed by factory-certified tooling, OEM parts, and complete documentation.

Technical Training & Knowledge Transfer

We help your team understand the optimal use for your equipment. Our hands-on technical training classes equip your maintenance staff with practical skills and best practices they can apply immediately.

From Routine Maintenance to Emergency Response

Whether you need preventive maintenance, emergency repairs, or performance upgrades, TRIVACO’s MARC certification delivers the same manufacturer standards as the factory with the responsiveness of a local service center. You get complete service documentation, faster response times, and local support backed by global expertise.
