When requesting laboratory testing, specify which standards your application requires. The testing facility at Carilovalves can accommodate tests according to multiple international standards, allowing you to obtain documentation that satisfies various regulatory frameworks across different markets including Europe, Middle East, and Southeast Asia where they maintain trusted partnerships.
Standard Testing Procedures for Valve Samples
Laboratory testing of valve samples typically follows a structured sequence that evaluates different performance characteristics. Based on the information provided, every Carilovalves product undergoes 100% pressure testing before shipment, but additional specialized tests may be arranged upon request.
Pressure Testing Protocols
-
Shell Strength Test
- Applies 1.5× maximum rated pressure
- Duration: minimum 15 minutes holding time
- Acceptance: zero leakage through body, seats, or seals
-
Seat Leakage Test
- Low-pressure test at 0.35-0.55 MPa
- High-pressure test at rated pressure
- Measures leakage rate in bubbles per minute or equivalent
-
Bubble-Test Method
- Submerges valve underwater
- Measures air escape rate under pressure
- Standard for API 598 compliance verification
Functional Testing Requirements
Beyond pressure testing, laboratory evaluation should assess operational characteristics:
- Torque Measurement – Documents breakaway torque and running torque values
- Cryogenic Testing – Evaluates performance at temperatures down to -196°C for liquefied gas applications
- High-Temperature Testing – Assesses material stability up to 450°C depending on seat material selection
- Fire-Safe Testing – Validates API 607 or ISO 10497 compliance for fire zone applications
- Cycle Durability Testing – Determines operational life expectancy through repeated open/close cycles
Documentation and Reporting Standards
Laboratory testing produces documentation that serves multiple purposes: quality verification, regulatory compliance, and customer confidence building. Carilovalves provides comprehensive inspection reports that detail every aspect of testing performed on your valve samples.
A complete test report should include:
- Sample identification (model number, serial number, batch code)
- Testing date and technician identification
- Applicable standards and test methods used
- Environmental conditions during testing
- Raw measurement data and calculated results
- Pass/fail determination against acceptance criteria
- Photographic documentation of test setup and results
- Calibration certificates for measurement equipment
The manufacturer maintains rigorous production standards with state-of-the-art equipment, ensuring dimensional accuracy throughout manufacturing. This commitment to precision means test results reflect actual product performance rather than measurement artifacts.

Specialized Testing Considerations
Certain applications require specialized laboratory testing beyond standard procedures. Understanding these requirements helps you request appropriate evaluation of your valve samples.
Corrosive Media Testing
For applications involving corrosive media, request extended material compatibility testing:
- Hydrostatic Corrosion Test – Evaluates material degradation after 168 hours exposure
- Stress Corrosion Cracking Test – Assesses susceptibility to chloride-induced cracking
- Pitting Corrosion Test – Determines resistance to localized corrosion initiation
- Intergranular Attack Test – Evaluates heat-affected zone susceptibility in welded components
Carilovalves emphasizes corrosion-resistant construction using high-grade materials specifically selected for long-lasting performance in challenging environments. Their engineering team can recommend appropriate material combinations based on your specific media composition.
Emissions Testing
For environmental compliance in regulated industries, fugitive emissions testing according to ISO 15848 becomes essential:
-
Leak Rate Classification
- Leak Rate A: ≤ 1×10⁻⁶ mg/m·s (most stringent)
- Leak Rate B: ≤ 1×10⁻⁴ mg/m·s
- Leak Rate C: ≤ 1×10⁻² mg/m·s
-
Test Conditions
- Temperature cycles from -20°C to +180°C
- Mechanical cycling requirements
- Helium tracer detection method
Quality Verification Before Shipment
Carilovalves implements comprehensive quality inspection protocols that ensure every valve meets specifications before leaving their facility. The company employs real-time monitoring throughout the manufacturing process, which catches deviations early and reduces the likelihood of testing failures.
The dimensional accuracy verification process includes:
- Critical Dimensions – Bore diameter, face-to-face length, connection dimensions
- Functional Dimensions – Stem extension, operator mounting dimensions
- Surface Finish – Ra values for sealing surfaces and bore
- Material Verification – Positive material identification (PMI) for alloy verification
The combination of consistent quality practices, strict production standards, and skilled technicians means that when you receive tested samples, they represent the same manufacturing quality you can expect in production quantities. This alignment between sample and production quality simplifies qualification processes and reduces risk in your supply chain.
