ISO 5599-1 Manual Control Valves Product Catalog

Key Features and Design Benefits

The ISO 5599-1 valves feature a spool design that is highly tolerant of contaminated air and is self-compensating for wear, extending service life and reducing maintenance frequency. Mounting options include individual sub-base mounting for standalone installations and manifold base mounting for multi-valve banks. Rugged construction uses corrosion-resistant materials throughout, and the aluminum bar stock valve body provides a durable, lightweight platform. The valves carry both a Declaration of Conformity and a Certificate of Compliance.

ISO Sizes and Flow Capacities

ISO Size 1 offers manifold inlet port sizes from 1/8 inch to 3/8 inch with a flow capacity of CV 1.0 (980 Nl/min) and weighs approximately 0.9 lb (0.4 kg). ISO Size 2 provides port sizes from 3/8 inch to 1/2 inch with a flow capacity of CV 2.0 (2,000 Nl/min) and weighs approximately 1.5 lb (0.7 kg). ISO Size 3 uses 1/2-inch to 3/4-inch ports with a flow capacity of CV 4.0 (3,900 Nl/min) and weighs approximately 2.0 lb (0.9 kg). This progression allows engineers to select the right combination of flow capacity and physical size for their application.

5/2 Valve Configurations and Ordering Information

The 5/2 manual control valves are available in all three ISO sizes with hand lever and palm button operators. Actuation options include detented (the valve stays in the shifted position after the operator is released) and spring return (the valve automatically returns to its original position when the operator is released). The model number configurator encodes the ISO size, port size and type, valve function, actuation method, and operator type.

For the 5/2 valves, the flow data at the 1-2 path shows CV 1.5 (1,500 Nl/min) for ISO Size 1, CV 2.0 (2,000 Nl/min) for ISO Size 2, and CV 4.5 (4,400 Nl/min) for ISO Size 3. Optional features include dustproof vent port covers and fluoroelastomer seal upgrades. Model number examples include I200BAFM for a hand lever detented valve in ISO Size 2.

5/3 Valve Configurations and Center Position Options

The 5/3 manual control valves offer three center position options: closed center (all ports blocked in the center position), open center (all ports interconnected in the center position), and power center (pressure connected to cylinder ports in the center position). Each center option is available with either detented or spring-center actuation, and with either hand lever or palm button operators.

The 5/3 valve flow capacities mirror the 5/2 versions, with CV 1.5 (1,500 Nl/min) for ISO Size 1, CV 2.0 (2,000 Nl/min) for ISO Size 2, and CV 4.5 (4,400 Nl/min) for ISO Size 3. The comprehensive model number configurator allows engineers to specify the exact combination of ISO size, center condition, actuation type, operator, seal material, and dustproof option needed for their application.

Sub-Bases for Individual Valve Mounting

Side-ported single sub-bases are available for standalone valve installations. The sub-bases use NPT threaded ports and are available for all three ISO sizes. ISO Size 1 sub-bases (Model 7107-501) have 1/8-inch cylinder ports and 1/4-inch in/out ports. ISO Size 2 sub-bases (Model 7112-502) have 1/2-inch ports. ISO Size 3 sub-bases (Model 7129-502) have 3/4-inch ports.

The catalog provides detailed dimensional drawings for each sub-base, including port locations, mounting bolt patterns, and overall envelope dimensions. All dimensions are provided in both inches and millimeters. Downloadable CAD models are available for design integration.

Manifold Bases, End Stations, and Accessories

Manifold bases are available in both side-ported and bottom-ported configurations. Side-ported manifold bases are offered for ISO Sizes 1, 2, and 3 in both NPT and G thread options. Bottom-ported manifold bases are available for ISO Sizes 1 and 2. Each manifold installation requires an end station kit to be ordered separately. Connectors and gaskets are included with each manifold base, and ISO Size 1 and 2 manifold bases include 3 O-rings and 2 connector brackets.

End stations provide the inlet and exhaust connections for the manifold assembly. Port sizes range from 3/8 inch for ISO Size 1 to 1 inch for ISO Size 3. End stations are available in both NPT and G thread options. Manifold accessories include blanking plates for covering unused manifold stations. The blanking plates consist of a metal plate, a gasket, and mounting bolts, and are available for all three ISO sizes.

Exhaust Silencers

High-flow exhaust silencers are available as accessories in both zinc-plated steel and stainless steel. Port sizes range from 1/8 inch to 3/4 inch with NPT and R/Rp thread options. Flow capacities range from CV 1.3 (1,300 Nl/min) for the 1/8-inch model to CV 14 (14,000 Nl/min) for the 3/4-inch model. The maximum pressure rating for all silencers is 300 psig (21.1 bar). These silencers reduce noise during valve exhaust while maintaining adequate flow capacity to avoid back-pressure issues.

Technical Specifications and Operating Conditions

All ISO 5599-1 manual control valves operate on filtered air at pressures from 0 to 150 psig (0 to 10.3 bar). The standard operating temperature range is 0°F to 123°F (-18°C to 50°C) for both ambient and media conditions. The spool construction design uses an aluminum bar stock valve body with Buna-N seals as standard. Fluoroelastomer seals are available as an option for applications requiring enhanced chemical or temperature resistance.

Port connections are available in NPT and G thread standards to support both North American and international installations. The catalog provides comprehensive dimensional drawings for all valves, sub-bases, manifold bases, end stations, and accessories, with all dimensions given in both inches and millimeters. Downloadable CAD models are available for all components.

Frequently Asked Questions

What does ISO 5599-1 compliance mean for these valves?

ISO 5599-1 is an international standard that defines the mounting interface dimensions for pneumatic directional control valves. Compliance ensures that AV valves are dimensionally interchangeable with any other manufacturer's ISO 5599-1 valves, sub-bases, and manifold systems. This gives users flexibility to mix and match components and simplifies replacement and maintenance.

What ISO sizes are available and how do they differ?

Three ISO sizes are available: Size 1 (smallest, CV 1.0-1.5, 1/8 to 3/8-inch ports), Size 2 (mid-range, CV 2.0, 3/8 to 1/2-inch ports), and Size 3 (largest, CV 4.0-4.5, 1/2 to 3/4-inch ports). Each larger size provides higher flow capacity for driving larger cylinders and actuators.

Can these valves be mounted on manifolds?

Yes. Manifold bases are available in both side-ported and bottom-ported configurations for all ISO sizes. Each manifold installation requires an end station kit to provide inlet and exhaust connections. Blanking plates are available for unused manifold stations.

What is the difference between detented and spring-return actuation?

Detented actuation means the valve stays in the shifted position after the operator (hand lever or palm button) is released, requiring a second actuation to return. Spring-return actuation means the valve automatically returns to its original position when the operator is released. The choice depends on whether the application requires maintained or momentary control.

Are both NPT and G thread port options available?

Yes. Sub-bases, manifold bases, and end stations are available in NPT thread for North American installations and G thread for international applications. This makes the AV ISO 5599-1 valve range suitable for global deployment.
