5/2-Way Double Valves with CROSSMIRROR® Sensing

Product catalog summary

Introduction
The document introduces the ROSS 5/2-way double valve with CROSSMIRROR® sensing, highlighting its role in enhancing safety and reliability in pneumatic systems, particularly for presses.

Product Description
The valve features two solenoid pilot valves with crossflow channels for synchronized movement, ensuring high safety standards. It includes a check valve and a bleed orifice for managing air pressure loss.

Specifications
- Design: Metal-to-metal spool-and-sleeve, pressure-operated, air and spring returned.
- Operation: Solenoid-operated, air-piloted, 3/2-way spring-return.
- Media: Compressed air, filtered (5 µm), lubricated or unlubricated.
- Operating Pressure: 2.5 to 10 bar.
- Temperature Range: 4°C to 50°C.
- Mounting: Preferably vertical.
- Monitoring: Dynamically, cyclically, internally.
- Standard Voltages: Various options including 24 V DC and 230 V 50 Hz.

Model Numbers and Dimensions
Details on various models, nominal pipe sizes, and mounting dimensions are provided.

Replacement Parts
Lists of replacement parts with part numbers and descriptions are available for valves with and without pressure switches.

Flow Characteristics and Valve Response Times
Flow characteristics are detailed with kv-values, and response times are provided for different pressures and models.

General Information
The optional pressure switch unit signals malfunctions. The valve is self-monitoring, designed for pneumatic presses, ensuring safety through synchronized solenoid control.

Cautions
Installation should be by trained personnel, with air supply lines meeting safety regulations. Proper air preparation and compliance with safety standards for silencers and electrical piloting are essential.

Conclusion
The ROSS 5/2-way double valve with CROSSMIRROR® sensing is a significant advancement in pneumatic safety technology, offering robust features for industrial applications.

Specifications and Components
Key components include a pressure switch, double-acting cylinder, and pressure gauge. Shock-absorbing mounting may be necessary in high-vibration environments.

Operating Instructions
Pressure failure tests and regular check valve inspections are recommended. Immediate inspection or replacement is advised in case of malfunctions.

Maintenance and Testing
Maintenance should follow national safety guidelines, using original ROSS parts, and be documented annually.

Start-up Procedures
Thorough checks are necessary before start-up to ensure pressure limits are not exceeded, with functional tests confirming proper operation.

Pre-Installation or Service Cautions
Ensure the electrical supply is off and the pneumatic system is exhausted before servicing. Only trained individuals should handle installations and maintenance.

Filtration and Lubrication
A 5-micron filter is recommended, and only compatible lubricants should be used to prevent damage.

Avoid Intake/Exhaust Restriction
Air flow in supply lines or exhaust ports should not be restricted to prevent erratic operation.

Double Valves
For hazardous machinery, a press control double valve with a monitoring device is essential to inhibit operation in case of failure.

Warranty
ROSS products are warranted against defects for one year, covering repair, replacement, or refund, excluding misuse or improper maintenance.

Start-up Prior to start-up, the installation must be checked thoroughly by persons trained and experienced in theoperation of pneumatic equipment. Make sure that the maximum operating pressure specified on the valvelabel will not be exceeded. When operating pressure is applied, the cylinder piston must move into the at-rest-position. For further testing, a functional test as well as a pressure failure test must be performed.

Only use lubricants which are compatible with materials used inthe valves and other components in the system. Normally, compatible lubricants are petroleum base oils with oxidation inhibitors, an aniline point between 82C and 104谰C, and an ISO 32, or lighter, viscosity. Avoid oils with phosphate type additives which can harm polyurethane components, potentially leading to valve failure and/or human injury. Before servicing a valve...
