The Significance of CRN Registration

CRN registration is fundamental for manufacturers and end-users operating pneumatic systems in Canada. Each province and territory maintains its own registration requirements, but modern reconciliation agreements enable streamlined mutual recognition across participating jurisdictions. This catalog represents ROSS Controls' commitment to providing products that meet the stringent safety standards defined by Canadian regulatory bodies and align with ASME B31.3 Process Piping Code requirements.

The CRN identifier itself provides critical information through its numeric designation following a decimal point. The first digit indicates the initial registering jurisdiction, while additional digits represent provinces that have subsequently accepted the design. A letter "C" designation indicates registration across all Canadian jurisdictions, demonstrating the broadest possible compliance coverage.

Comprehensive Product Portfolio with CRN Registration

This catalog presents ROSS Controls' extensive line of directional control valves available in multiple configurations and sizes. The portfolio includes both poppet and spool sleeve designs, accommodating diverse industrial applications from standard industrial automation to safety-critical pneumatic systems requiring enhanced monitoring and control.

The 27 Series Directional Control Valves represents ROSS's solenoid pilot-controlled poppet valve technology, engineered for compact installation, low weight, and consistent response times throughout the valve's operational life. These valves feature innovative design characteristics including momentary control capabilities from single pressure sources, internal or external pilot supply options, and actuating force multipliers suitable for low signal pressure applications. Multiple body sizes from 3/8" to 2" accommodate flow requirements ranging from 2.3 to 72 Cv (flow coefficient), addressing applications from precision control circuits to high-flow industrial systems.

The 21 Series Valves extend product capabilities into extreme temperature environments. ROSS engineers have configured these poppet valves with selectable internal components to provide high-temperature service up to 300°F (150°C) media temperature or low-temperature operation down to -40°F (-40°C). Fluorocarbon seals ensure stability in elevated temperature applications, while specialized designs support vacuum service requirements and leak-tight applications critical to sensitive manufacturing processes.

Safety-Critical Fluid Power Solutions

Safety-related products constitute a major component of this CRN catalog. The L-O-X® Manual Lockout Valves and Series 27 Piloted Valves with Lockout Control provide energy isolation functions essential for protecting workers during equipment maintenance and setup operations. The EEZ-ON® Valve Series combines lockout functionality with advanced control features, streamlining complex safety system designs.

The M35 Series Control Reliable Double Valves and DM2® Series represent state-of-the-art safe exhaust and clutch/brake control technology. These dual-poppet designs incorporate dynamic monitoring with integrated memory functions, ensuring that valves lock out immediately upon detecting asynchronous movement of valve elements during actuation or deactuation cycles. Unlike traditional designs, these systems retain a residual outlet pressure of less than 1% of supply pressure when locked out, providing exceptional safety assurance for mechanical power presses and hazardous machinery applications.

DM2® Series valves achieve Category 4 PL e compliance under ISO 13849-1 standards and SIL 3 certification in redundant configurations, meeting the most stringent international safety requirements for machinery protection. These designs incorporate pressure monitoring switches providing real-time status feedback to control systems, enabling predictive maintenance and immediate fault detection.

International Standards & Certifications

All products featured in this CRN catalog have undergone rigorous engineering review and testing to comply with applicable Canadian provincial regulations and adopted safety codes. The catalog specifically documents ASME B31.3 Process Piping Code registration, the standard governing most pneumatic and fluid power installations in industrial facilities.

TÜV Rheinland certification confirms Safety Integrity Level 2 (SIL 2) and Performance Level c under IEC 61508, IEC 61511, and EN ISO 13849-1 standards. This independent third-party validation demonstrates that ROSS products meet internationally recognized safety requirements, providing confidence to engineers, integrators, and end-users operating in regulated industries.

Port Sizes, Configurations, and Technical Specifications

The catalog provides detailed specifications for valve models featuring NPT and BSPP thread options, accommodating both North American and European industrial standards. Body sizes range from compact 3/8" models suitable for space-constrained applications to robust 2" and 2.5" systems designed for high-flow industrial processes.

Operating pressure ranges typically span from 15 to 150 psig for standard applications, with specialized pressure-controlled variants extending to 300 psig operation. Multiple flow coefficient (Cv) ratings enable engineers to select precisely sized components that optimize energy efficiency while maintaining responsive system performance.

Engineering Resources and Installation Guidance

This comprehensive catalog includes dimension drawings for all valve configurations, mounting specifications, and electrical connection details.
