Valves – CRN Design, Compliance & Approval
Code-Compliant Valve Engineering for Safe, Reliable and Regulator-Ready Operation
Valves used in pressure equipment across Canada require CRN approval to ensure they meet the safety, performance, and construction requirements outlined in CSA B51, ASME standards, and provincial regulations.
Each valve—whether standard, custom, or part of a larger assembly—must demonstrate compliance through detailed engineering documentation, material data, design ratings, and testing records.
At KopfkinoGroup India, we prepare complete CRN submission packages for all valve types, ensuring seamless approval across all Canadian provinces and territories.
Applicable Standards for Major Valve Types
- Butterfly Valves — API 609 / ASME B16.34 Defines design rules for lug and wafer types; B16.34 may also apply.
- Plug Valves — ASME B16.34 / MSS SP-78 / SP-105 MSS standards specify additional requirements for specific plug valve types.
- Pressure Relief Valves — ASME Section VIII UG-125 to UG-137 / ASME Section I Defines sizing, performance, construction, and test requirements.
- Control Valves — ASME B16.34 + ISA Standards (e.g., ISA 75.01) Covers pressure design; ISA standards guide control performance.
Applicable Standards for Major Valve Types
- Ball Valves — ASME B16.34 For flanged, threaded, and welded ends; covers materials, pressure-temperature ratings, and testing.
- Gate Valves — ASME B16.34 / API 600 / API 602 Used for steel gate valves; API standards define design and performance criteria.
- Globe Valves — ASME B16.34 Governs construction, pressure ratings, and temperature limits.
- Check Valves — API 594 / ASME B16.34 API 594 covers wafer & lug type designs; B16.34 covers general pressure design requirements.
Why CRN Approval Matters for Valves
CRN ensures valves are:
- Safe for use in high-pressure systems
- Designed in accordance with recognized international codes
- Constructed from approved materials
- Tested for leak-tightness, strength, and durability
- Acceptable for installation across all Canadian provinces
A properly prepared CRN submission prevents delays and ensures legal compliance.
