Parts & replacement units
We stock common gasket/seal kits and service parts for rapid turnaround. When a unit is beyond economical repair, we can provide replacement actuators and handle fit-up (brackets, couplings, drives).
Field service & start-ups — commissioning, troubleshooting, loop checks, limit and torque setting.
Shop overhaul & refurbishment — teardown, inspection, cleaning, OEM gasket and seal kits, reassembly, test report.
Diagnostics & calibration — travel limits, torque switches, insulation checks, heater verification, and load verification when applicable.
Parts & upgrades — genuine spares, control boards, gasket/seal kits, modernization paths for legacy units.
Valve automation packages — actuator sizing, bracket/drive design, assembly, testing.
Preventive maintenance — scheduled inspections, lubrication, environmental sealing checks, recommended spares.
Water ingress / failed seals → replace gasket/seal kits, restore sealing surfaces.
Calibration drift / nuisance trips → re-set travel limits and torque, verify under operation.
Obsolete components → identify direct replacements or upgrade options.
Slow/erratic operation → gear train inspection, lubrication, motor/controls checks.
Electrical faults → wiring checks, board replacement, terminal and heater checks.
Request — share model, serial, symptoms, environment (NEMA/IP), and urgency.
Diagnose — field visit or bench test to confirm root cause and required parts.
Quote — scope, parts list, turnaround (rush or standard).
Repair — OEM parts installed; torque/limit set; function verified.
Report — test sheet with readings, photos, and maintenance recommendations.
