Key Features and Performance Advantages

Individual Valve Shut-Off for Maximum Uptime

One of the most significant innovations in the PACK Series design is the automatic individual valve shut-off capability that enables maintenance personnel to service, replace, or troubleshoot individual valve stations without shutting down the entire manifold assembly or halting continuous production processes. This feature dramatically increases operational uptime by allowing targeted maintenance activities while the remainder of the system continues normal operation, preventing costly production interruptions and minimizing downtime expenses in continuous processing environments such as food and beverage production, pharmaceutical manufacturing, chemical processing, and automated packaging lines.

The individual shut-off mechanism is automatically engaged when a valve is removed from the manifold, immediately isolating that station's air supply and exhaust ports to prevent air loss and maintain system pressure across all remaining active stations. This design consideration reflects ROSS Controls' deep understanding of real-world manufacturing challenges where unplanned downtime can cost thousands of dollars per minute and where maintenance windows are increasingly compressed to maximize production capacity.

Sure-Shifting and Self-Cleaning Operation

PACK Series valves incorporate a unique sure-shifting mechanism that maintains consistent, reliable actuation throughout the valve's operational lifespan, even in the harshest industrial environments. The self-cleaning design actively resists contamination buildup that can compromise valve performance in conventional designs, making these manifolds exceptionally well-suited for applications where filtered air quality cannot always be guaranteed or where environmental conditions include excessive dust, moisture, oil carryover, or particulate contamination.

This dirt-tolerant construction proves especially valuable in heavy industrial applications such as steel mills, foundries, mining operations, cement plants, woodworking facilities, and agricultural processing where ambient air quality frequently falls below ideal pneumatic system standards. The valves demonstrate reliable shifting performance across extreme temperature ranges from 39°F to 175°F (4°C to 50°C for ambient, extending to 80°C for media temperature), accommodating seasonal temperature variations and process heat exposure without performance degradation.

Positive Sealing with Perpendicular Poppet Design

The PACK Series employs a perpendicular poppet face seal design that provides superior sealing performance compared to traditional spool valve constructions. This geometric arrangement creates a positive seal that automatically compensates for wear over the valve's service life, maintaining zero-leak performance and eliminating the gradual performance degradation typically associated with conventional valve designs as sealing surfaces wear.

The poppet construction utilizes high-performance Buna-N seals combined with acetal and stainless steel poppet materials to deliver exceptional chemical resistance, wear resistance, and sealing reliability. The perpendicular orientation of the poppet face against the seat ensures consistent sealing force regardless of pressure variations, temperature fluctuations, or seal material aging, providing long-term reliability and predictable performance characteristics throughout extended service intervals.

Quick Electrical Disconnect with Integrated Status Indication

Every PACK Series valve station features quick electrical disconnect capability with an integrated indicator light that provides immediate visual confirmation of valve energization status. This design element significantly accelerates troubleshooting activities by allowing maintenance technicians to quickly identify energized valves, verify control signals, and diagnose electrical or pneumatic faults without requiring measurement instruments or complex diagnostic procedures.

The quick disconnect feature employs EN 175301-803 Form A or Form C electrical connections depending on configuration, providing secure, vibration-resistant connections that can be rapidly disconnected and reconnected during maintenance activities. The indicator lights are positioned for optimal visibility in typical installation locations, enabling operators and technicians to assess valve status at a glance from normal working distances, reducing troubleshooting time and accelerating problem resolution in production environments.

Technical Specifications and Configuration Options

Available Valve Functions and Configurations

The PACK Series catalog details multiple valve function options to accommodate diverse application requirements:

3/2 Single Solenoid Valves (3-Way, 2-Position): Designed primarily for single-acting pneumatic actuators or applications requiring one output port, these valves provide normally closed or normally open configurations with spring return actuation. The 3/2 function is ideal for controlling spring-return butterfly valves, damper actuators, and single-acting cylinders commonly found in process valve automation.

5/2 Single Solenoid Valves (5-Way, 2-Position): Engineered for double-acting pneumatic actuators, these valves feature two output ports for controlling bidirectional actuator motion. The 5/2 configuration accommodates ball valves, knife gate valves, double-acting butterfly valves, and other process valves requiring precise position control in both directions. Available in normally closed configurations with spring return actuation for fail-safe operation.

The catalog provides detailed specifications for each valve function including flow capacity measured in Cv values (typically 0.5 Cv for PACK Series), response times, shifting forces, and recommended actuator sizing guidelines to ensure optimal performance matching between valve capacity and actuator requirements.

Port Sizes and Thread Specifications

PACK Series manifolds accommodate various port size combinations to match different actuator volumes and response time requirements:

• 1/8" NPT Outlet Ports: Suitable for small actuators, compact butterfly valves, and applications requiring slower actuation speeds or where space constraints demand minimal port sizes
• 1/4" NPT Outlet Ports: The most common configuration, providing balanced flow capacity for medium-sized actuators and typical industrial process valve applications
• 3/8" NPT Inlet and Exhaust Ports: Standard manifold supply and exhaust connections offering adequate flow capacity for most multi-station configurations
• 1/2" NPT Inlet and Exhaust Ports: Enhanced flow capacity for larger manifold assemblies or applications requiring faster actuator response times

All threaded connections conform to NPT (National Pipe Thread) standards ensuring compatibility with standard North American pneumatic fittings, tubing, and piping systems. The catalog includes torque specifications and thread sealant recommendations to ensure leak-free installations and optimal system performance.

Electrical Specifications and Voltage Options

The PACK Series offers comprehensive voltage options to accommodate global electrical standards and diverse facility power configurations:

24 VDC Operation: Low voltage DC operation is increasingly preferred in modern automated manufacturing facilities due to safety considerations, compatibility with PLC output modules, and reduced electrical installation costs. The 24 VDC configuration typically consumes 3.9 VA holding power with continuous duty rating, making it compatible with standard industrial power supplies and control systems.

110/120 VAC Operation: North American standard voltage option operating at 50/60 Hz with minimal power consumption of 0.03 VA holding power for extremely energy-efficient operation. The AC solenoid design incorporates inrush current limiting to prevent nuisance circuit breaker tripping during simultaneous multi-valve energization.

230 VAC Operation: International voltage standard for European and Asian markets, providing consistent performance across global installations and facilitating standardization for multinational corporations operating facilities in multiple regions.

All electrical specifications include continuous duty ratings, meaning valves can remain energized indefinitely without thermal damage, overheating, or performance degradation—a critical requirement for applications where valves must maintain position for extended periods during process operations.

Multi-Station Manifold Configurations
