80 Series SAE Valves – Installation & Operating Instructions
Overview
The ROSS Controls® 80 Series is a premium-quality stainless-steel spool-and-sleeve pneumatic valve designed for SAE interface base mounting. Available in SAE sizes 125, 250, and 500, the 80 Series delivers reliable directional control in automotive manufacturing and heavy industrial applications. ROSS Controls, founded in 1921 and with over 100 years of fluid power expertise, designed the 80 Series to meet the demanding performance and interface standards of the SAE pneumatic valve market.
The 80 Series supports both solenoid pilot and pressure pilot control, and is characterized as a multipurpose valve in which any port may be restricted and/or pressurized provided sufficient pilot pressure is maintained. This flexibility supports a wide range of circuit configurations. Electrical connections are made via 5-pin connectors, with specific Ford-wired and Chrysler-wired mini and micro connector configurations available.

Key Features
Stainless Steel Spool-and-Sleeve Construction
The 80 Series features a stainless steel spool within a cast aluminum valve body, providing corrosion resistance and dimensional stability for long service life. The matched spool-and-sleeve assembly delivers precise flow control with consistent repeatability. Buna-N seals provide media compatibility with filtered air and lubricant-containing air supplies.
SAE Interface Sizes 125, 250, and 500
Three SAE interface sizes are available. SAE 125 and 250 models suit compact to medium-flow applications, while the SAE 500 handles high-flow requirements. The SAE interface allows direct mounting on SAE-compliant sub-bases and manifolds, enabling seamless integration into existing SAE pneumatic systems common in automotive and heavy manufacturing environments.
Ford and Chrysler Wired Connector Options
The 80 Series is available with multiple pre-wired electrical connector configurations to suit OEM equipment requirements. Ford-wired 5-pin mini-connectors (all voltages) and 4-pin micro-connectors (24 VDC) are available. Chrysler-wired 5-pin mini-connectors (all voltages), 5-pin micro-connectors (24 VDC), and 5-pin micro-connectors (120 VAC/60 Hz) cover the major Chrysler interface standards. Power is supplied via the 5-pin connector or conduit in the top of the valve.
SAE Port Designation
The 80 Series uses SAE port designations: Port P (Inlet), Ports A and B (Outlets), and Ports EA and EB (Exhausts). Exhaust ports EA and EB may be restricted to control cylinder speed. An external pilot supply port X in the base must be plugged when using internal pilot supply to prevent air escape.

Applications
Automotive Assembly Line Equipment
The 80 Series was engineered for the automotive industry, with SAE interface compatibility and Ford/Chrysler wired connector options that simplify integration into OEM automotive assembly equipment. High-volume automotive production lines use 80 Series valves for pneumatic cylinder actuation in body assembly, welding, and transfer press operations.
Heavy Manufacturing and Multipurpose Applications
Beyond automotive, the 80 Series serves heavy manufacturing applications in metalworking, stamping, and material handling. The stainless steel spool construction provides durability in environments with coolant mist, cutting fluid vapor, and other mild corrosives, while the SAE interface supports integration with existing base-mounted SAE valve systems.
Safety and Compliance Standards
All installation and maintenance of 80 Series valves must be performed by trained pneumatic equipment personnel. Before any service, disconnect electrical supply, shut off air supply, and exhaust all system pressure. Use a 5-micron rated air filter in the inlet line. The voltage ratings of solenoids are printed on the top plate of the valve; the electrical supply must match these ratings exactly.
Installation and Setup Guide
Base and Electrical Connector Selection
80 Series valves and bases must be purchased separately. Select the appropriate SAE size base to match the valve. Select the electrical connector type (Ford or Chrysler configuration) matching your OEM equipment wiring standard. Power is supplied via the 5-pin connector or conduit in the top of the valve.
Pilot Supply Configuration
For solenoid-controlled models, pressure for pilot valves is supplied from the inlet port (internal pilot). Plug port X in the base to prevent internal pilot air from escaping. If inlet pressure is below the minimum required pilot pressure, connect an external pilot supply to port X in the base. For pressure-controlled models, connect pilot control lines to the base ports per specifications.
Spool-and-Sleeve Maintenance
To reassemble the spool and sleeve, apply one drop of Anderol 735 on each spool land, insert the spool into the sleeve, and rotate to distribute lubricant. Each spool-sleeve pair is a matched set; do not reverse spool position. Lightly lubricate O-rings with a compatible lubricant (not Anderol) before inserting the assembly into the valve body.

Frequently Asked Questions
Q: What SAE sizes are available in the 80 Series?
A: The 80 Series is available in SAE sizes 125, 250, and 500. Valves and bases must be purchased separately.
Q: What connector types are available for 80 Series solenoid models?
A: Ford-wired 5-pin mini-connectors (all voltages) and 4-pin micro-connectors (24 VDC) are available, as well as Chrysler-wired 5-pin mini-connectors (all voltages), 5-pin micro-connectors (24 VDC), and 5-pin micro-connectors (120 VAC/60 Hz). Power is supplied via the 5-pin connector or conduit in the top of the valve.
Q: What is the power consumption of 80 Series SAE 500 solenoid models?
A: SAE Size 500 solenoid models consume 14 watts on DC and 87 VA inrush, 30 VA holding on 50/60 Hz AC. SAE Size 125 and 250 models consume 8 watts on DC and 8 VA inrush, 6 VA holding on AC.
Q: What is the ambient temperature limit for 80 Series solenoid models?
A: Solenoid pilot 80 Series valves have an ambient temperature range of 40° to 120°F (4° to 50°C) and a media temperature range of 40° to 175°F (4° to 80°C). Pressure-controlled models support ambient and media temperatures of 40° to 175°F (4° to 80°C).
Q: Can the exhaust ports on the 80 Series be restricted?
A: Yes. Exhaust ports EA and EB may be restricted to control cylinder speed. To reduce exhaust noise, use an efficient ROSS silencer. Avoid excessive restriction that could adversely affect valve performance.
Q: How is the external pilot supply connected on 80 Series valves?
A: If the valve must operate with inlet pressure below the required pilot pressure, connect an external pilot supply to port X in the base. For vacuum or non-air service, an external pilot supply is always required. Plug port X when using internal pilot supply.
Q: What solvent should be used to clean 80 Series spool-and-sleeve assemblies?
A: Use a solvent that dries without leaving residue – this is especially important for the spool-and-sleeve assembly. Do not use chlorinated solvents (damage seals) or abrasive materials (permanent metal damage).
Q: Where can I get service kits for the 80 Series?
A: Service kits are available from ROSS Controls and authorized distributors. Contact ROSS at 1-800-GET-ROSS or visit www.rosscontrols.com. Service kit details are listed on page 3 of the official 80 Series installation document (Doc ID 65).
