SERPAR® Crossflow Double Valves with Pressure Switches

Product catalog summary

General Information: The SERPAR® Crossflow Double Valves with Pressure Switches are designed to enhance safety in pneumatically controlled presses and machinery. They feature two independent valve elements within a single housing, each actuated by separate solenoid pilot valves. This ensures safety by maintaining outlet pressure below 2% of inlet pressure if one valve element fails, preventing operation of clutches or brakes.

Valve Sizes and Construction: Available in sizes 4, 8, 12, and 30, the valves come with threaded or flanged ports. The housing is made of die-cast aluminum, and the valve elements are lightweight for quick response and durability.

Pressure Switches: Mounted on an adaptor, these switches monitor pressure in the crossflow passages, ensuring simultaneous movement of both valve elements. Malfunctions result in unmatched signals, triggering a system shutdown.

Operation: Both solenoids must be energized simultaneously to shift the valve, requiring a maintained signal to keep it shifted. A spring return mechanism is included, and abnormal signal pairings indicate malfunctions, prompting the external monitoring system to inhibit further valve actuation.

Specifications: The valves operate with pilot solenoids rated for continuous duty, available in various standard voltages. They require filtered air with a pressure range of 2 to 8.5 bar and operate within ambient temperatures of 4°C to 50°C.

Safety and Compliance: The valves meet European safety standards and are certified by various authorities. They must be used with an external monitoring system capable of inhibiting operation in case of valve failure.

Important Notes: Modifications to valve configurations void product liability insurance. Pressure switches are for monitoring valve function only, and adjustments should not be changed.

Diaphragm Pressure Switch Specifications: Model 518E30 includes sizes 4, 8, 12, 30, connector socket model 522E30, and zinc plated steel body. It operates with a maximum current of 250 V~ and has a mechanical life of 106 operations at pressures up to 50 bar, protected to IP 65 standards, with a temperature range of -30°C to +100°C.

Procedures: Pre-installation and service procedures emphasize turning off all energy sources and ensuring the pneumatic system is shut off and exhausted before servicing. Only trained personnel should install or service ROSS products, with regular checks and maintenance recommended.

Standards and Recommendations: A 5-micron filter is recommended for normal applications to prevent contaminants. Certain fluids should not be used with polycarbonate plastic bowls, and compatible lubricants with petroleum base oils are advised.

Warnings and Cautions: The warranty covers defects in material and workmanship for one year, with limitations on misuse and improper maintenance. Liability for incidental or consequential damages is disclaimed, and the use of ROSS parts for repairs is emphasized.

Connection and Monitoring: A block schematic connection diagram is provided for the suggested connection between the AZR 20P2*-Unit and the press control system, including details on short circuit protection and monitoring logic.

Contact Information: Contact details for ROSS offices in the UK, USA, Germany, Brazil, Japan, India, and China are provided.

PRE-INSTALLATION or SERVICE 1. Before servicing a valve or other pneumatic component, besure 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: EN 1037).2. All ROSS products, including service kits and parts, should beinstalled and/or serviced only by persons having training and ex-perience with pneumatic equipment. Because any installationcan be tampered with or need servicing after installation, persons responsible for the safety of others or the care of equipment must check every installation on a regular...
