Product Overview and Key Features

The ROSS 95 Series Slim-Line Valves are precision-engineered directional control valves designed to deliver exceptional reliability, compact construction, and high flow capacity in a versatile package suitable for diverse industrial automation applications. These valves feature innovative design characteristics that set them apart in the pneumatic control valve market.

Core Design Features

Flexible Mounting Options: The 95 Series valves offer exceptional installation versatility with both inline and manifold mounting capabilities. This dual-mounting design allows engineers and maintenance personnel to adapt valve configuration to specific space constraints and system architectures, whether installing individual valves in compact spaces or building comprehensive manifold assemblies for complex multi-actuator systems.

Resilient Seal Spool Construction: At the heart of every 95 Series valve is a durable resilient seal spool design that ensures positive sealing, wear resistance, and long operational life. The spool and sleeve construction incorporates high-quality seal materials including Buna-N and Viton options, providing excellent compatibility with both lubricated and non-lubricated air service. This construction methodology minimizes internal leakage while maintaining fast response times across millions of cycles.

Compact Size with High Flow Capacity: Despite their slim profile and space-saving design, 95 Series valves deliver impressive flow capacity. The optimized internal flow paths minimize pressure drop while maximizing throughput, with Cv values ranging from 0.7 to 4.5 depending on port size and valve configuration. This combination of compact dimensions and high flow performance makes the 95 Series ideal for applications where space is limited but performance cannot be compromised.

Multiple Port Size Options: The 95 Series accommodates a comprehensive range of port sizes including 1/8", 1/4", 3/8", and 1/2" configurations. This extensive size range allows precise matching of valve capacity to application requirements, ensuring optimal system performance without over-sizing or under-sizing valve components. Thread options include both NPT (National Pipe Thread) and G (ISO parallel thread) configurations to accommodate global installation standards.

Valve Configurations and Functions Covered in This Catalog

3/2-Way Valve Configurations

The catalog includes comprehensive specifications for 3/2-way (3-port, 2-position) valve configurations available in single solenoid and single air pilot versions. These valves provide normally closed operation with spring return functionality, making them ideal for simple on/off control applications, pilot valve duties, and basic pneumatic circuit functions. Detailed technical data includes port locations, flow characteristics, electrical specifications, and dimensional information.

5/2-Way Valve Configurations

The 5/2-way valve section covers the most versatile configuration in the 95 Series lineup. Available in both single solenoid and double solenoid variants, as well as air pilot controlled versions, these valves enable bidirectional control of single-acting and double-acting pneumatic actuators. The catalog details:

• Single Solenoid Models: Featuring spring return to normally closed or normally open positions
• Double Solenoid Models: Offering detented (memory) operation that maintains the last commanded position
• Air Pilot Models: Providing reliable control in explosive atmospheres or electrically sensitive environments
• NAMUR Interface Options: Direct mounting to actuators per ISO 5599-2 and VDI/VDE 3845 standards

5/3-Way Valve Configurations

For applications requiring mid-position functionality, the 95 Series offers 5/3-way (5-port, 3-position) valve configurations with multiple center position options:

• Closed Center: All ports blocked in the center position for secure holding
• Open Center: Inlet blocked, outlets vented for rapid repositioning
• Pressure Center: Inlet connected to outlets for pressure balance applications

These valves provide double solenoid or double air pilot actuation with spring-centered operation, enabling sophisticated control strategies for complex automation sequences.

Technical Specifications and Performance Data

Operating Pressure and Media Requirements

All 95 Series valves operate within a pressure range of 22.5 to 150 psig (1.5 to 10 bar), providing reliable performance across standard industrial compressed air system pressures. The valves require filtered air per ISO 8573-1 standards to ensure long service life and prevent contamination-related failures. For solenoid pilot valves, internal pilot supply is derived from inlet pressure, requiring minimum pilot supply equal to or greater than inlet pressure for reliable shifting.

Electrical Specifications

The catalog provides complete electrical specifications for all solenoid-controlled valve models, including:

• Voltage Options: 24 VDC and 110/120 VAC configurations available
• Duty Rating: Continuous duty operation without derating
• Power Consumption: 2.5 watts for DC models, 3.6 VA holding for AC models (50/60 Hz)
• Solenoid Connections: Multiple connector options including EN 175301-803 (Industrial Form B, Form C, MICRO-MINI) for standardized electrical interface

Environmental Operating Conditions

Operating temperature ranges are specified for both ambient and media temperatures: 41°F to 140°F (5°C to 60°C). This range accommodates most industrial environments while protecting valve components from extreme temperature exposure that could affect seal integrity or solenoid performance.

Flow Performance and Cv Ratings

Detailed flow coefficient (Cv) data is provided for each valve model and port size combination, enabling accurate system sizing and pressure drop calculations. Flow capacities range from 0.7 Cv for 1/8" port valves up to 4.5 Cv for 1/2" port configurations, with corresponding Nl/min (normal liters per minute) ratings for international specifications.

Materials of Construction and Durability

Valve Body Materials

The 95 Series employs die-cast aluminum valve bodies, providing an optimal balance of strength, weight, and corrosion resistance. The aluminum construction ensures durability in industrial environments while maintaining the compact, lightweight profile essential for space-constrained installations.

Internal Components

• Spool/Poppet Material: Aluminum spools deliver smooth, low-friction operation with excellent wear characteristics
• Seal Materials: Buna-N (nitrile) seals as standard, with Viton (fluoroelastomer) options available for applications requiring enhanced chemical resistance or elevated temperature capability

Manifold Systems and Accessories

Manifold Mounting Options

The catalog includes extensive information on manifold base systems that enable multiple 95 Series valves to be assembled into integrated valve banks. Manifold configurations support 2 to 10 stations, providing common supply and exhaust passages while maintaining individual valve control. Benefits include:

• Compact system footprint
• Common exhaust management
• Simplified maintenance and valve replacement
• Optional integrated electrical connections

Sub-Bases and Individual Mounting

For applications requiring single valve installation, various sub-base options are detailed in the catalog, including ported bases that convert inline port configurations to bottom-ported installations for simplified piping.
