Certified to the Highest Global Standards
Every PERLA valve is designed, manufactured and tested under a rigorous quality management system backed by internationally recognized certifications and compliance with the most demanding industrial standards.
Quality Management System
PERLA operates under a certified ISO 9001 Quality Management System, ensuring consistent product quality, traceability and continuous improvement across all manufacturing and engineering processes.
European Conformity
The CE marking confirms that PERLA valves meet all applicable European Union directives — including the Pressure Equipment Directive (PED 2014/68/EU) — and are authorized for free circulation within the European Economic Area.
Compliance with International & European Standards
Our valves are engineered and tested in accordance with the most rigorous international and European technical standards, ensuring full interoperability and regulatory compliance in every market.
International & European Design Standards
Industrial Control Valve Design
The comprehensive standard for design, dimensions and flow coefficient calculation (Cv / Kv) of industrial control valves. EN 1349 is its direct European equivalent.
Control Valve Sizing & Performance
Developed by the International Society of Automation, this series governs the design, sizing, testing and overall performance of control valves across all service conditions.
Leakage & Seat Tightness
Control Valve Seat Leakage
Defines the leakage classes (I through VI) and permissible leakage limits at control valve seats, providing a universally accepted benchmark for internal tightness evaluation.
Design, Pressure & Materials
Valves — Flanged, Threaded & Welding End
Establishes design, pressure-temperature ratings and material requirements for cast and forged valves used in high-pressure and high-temperature applications.
Face-to-Face & End-to-End Dimensions
Standardize face-to-face and end-to-end dimensions of valves to guarantee interchangeability within piping systems across manufacturers and installations.
Testing & Inspection
Valve Inspection & Testing
Establishes procedures and requirements for hydrostatic and pneumatic pressure testing and inspection of valves, ensuring structural integrity and seat tightness before delivery.
Industrial Valves — Pressure Testing
Defines procedures for measuring leakage and sets acceptance criteria for pressure tests conducted with liquids or gases on industrial valves.
