TESTING, RECERTIFICATION AND REPAIR FOR ALL TYPES OF STEAM VALVES

We specialise in the testing, overhaul and re-certification of steam valves and fittings, providing both on-site mobile services and workshop-based refurbishment. Our experienced service engineers work across all makes and models of valves and actuators, supporting both insurance compliance and long-term plant performance.

Boiler safety valves are a critical component in maintaining the safe and reliable operation of any steam system. As part of annual compliance requirements, now routinely enforced by insurers, safety valves must be tested, recalibrated and certified every 12 months to ensure they function correctly under pressure.

Our Steam Valve Services include:

  • Safety valve testing and recalibration
  • Valve inspection and repair
  • Full overhaul and reconditioning
  • Actuator testing and functional checks
  • Certification to insurance standards

WHY REGULAR VALVE CERTIFICATION MATTERS

Safety Assurance: Prevent dangerous overpressure events by ensuring correct valve operation.

Regulatory Compliance: Meet insurer and legal requirements with documented annual certification.

System Efficiency: Ensure reliable performance and reduce the risk of steam losses or pressure irregularities.

Cost Control: Avoid unplanned downtime and expensive emergency repairs by identifying issues early.

ON-SITE VALVE CERTIFICATION ACROSS THE UK

Our mobile service vans are fully equipped with bench-mounted hydrostatic and pneumatic testing rigs, allowing us to perform pressure and leakage testing using water or nitrogen, all without removing valves from the site.

Advantages of Mobile Valve Testing

Minimised downtime: No need to decommission the boiler for extended periods

Cost-effective: No transport or handling charges

Fast turnaround: Most repairs and recalibrations are completed on-site

Comprehensive stock: We carry a wide range of parts for common valve types

Where more extensive refurbishment is required, we will remove and transport valves to our workshop for full reconditioning and re-certification.
