ROSS Valves for SAE Bases The SAE Standard Interface, though originally developed by U.S. auto companies in the early 1970s, has quickly gained wide acceptance throughout the industry. Due to the design's ruggedness and high-flow characteristics, the Society of Automotive Engineers (SAE) established it as a new standard. This ensures that valves designed to fit the SAE interface will be interchangeable, regardless of manufacturer. In practical terms, the user can change from one brand of valve to another without changing installed bases or manifolds. ROSS valves are available in SAE sizes 125,...

MANUAL OVERRIDES Each solenoid pilot has a non-locking override button for manual actuation of the valve. For Size 500 valves, locking buttons and extended buttons are also available. See page 9. VALVE RESPONSE TIME Average response constants for each valve are listed in the charts on pages 4 thru 6. These constants, designated M and F, can be used to determine the amount of time required to fill or exhaust a volume of any size by using the following formula: Valve Response Time (msec) = M + (F • V) SERIES 80 Spool Valve Construction The matched spool and sleeve used in each of these valves is...

Accessories Interposed Regulators Both single and dual interposed regulators are available for SAE sizes 125 and 250. Dual pressure regulators allow the pressure at each outlet port to be set independently. A regulator is sandwiched between the valve and sub-base or manifold station and the valve is then bolted through the regulator to the sub-base or manifold station with the longer bolts provided. Use dual pressure regulators with 80 Series valves only. When using dual pressure regulators, the valve must be externally piloted. Single pressure regulators supply the same regulated pressure at...

Cautions PRE-INSTALLATION or SERVICE 1. Before servicing a valve or other pneumatic component, be sure that all sources of energy are turned off, the entire pneumatic system is shut off and exhausted, and all power sources are locked-out (ref: OSHA 1910.147, EN 1037). 2. All ROSS products, including service kits and parts, should be installed and/or serviced only by persons having training and experience with pneumatic equipment. Because any installation can be tampered with or need servicing after installation, persons responsible for the safety of others or the care of equipment must check...
