1 Pilot operated solenoid valves for pneumatic actuators / and / way solenoid valves Orifice size 6 and mm and threaded connections Pressure range 0 () bar For air and inert gases With TÜV-approval up to AK-7 / SIL VALVE GROUP CP-

2 Valve group CP- The valve group CP- is part of the series of pilot operated solenoid valves. According to type and application, the valves are pilot operated with internal, or internal and external control air. Application The valves of the group CP- are used above all for the control of pneumatic actuators. With interface they are particularly suitable for quarter turn actuators. The integrated spring chamber ventilation protects actuators with from the hostile environments. The valves with external control air connections are recommended for quick exhaust applications with high flow rate and no minimum operating pressure. Thanks to a wide range of solenoids in various type of protection for hazardous areas and environmental protected valves, the group CP- solenoid valves are particularly valued in the chemical- and petrochemical industry. Standard models Design Pilot operated spool valve and poppet valve. Function According to type / way or / way, single or dual solenoid Pressure range bar and 0 bar depending on type (see type overview) Media Filtered, lubricated or lubricant-free compressed air Instrument air Nitrogen and other inert gases Flow direction See functional symbol Temperature ranges Medium: ( ) + C (+0º C) Ambient: ( ) + C (+0º C) Please observe the allowed ambient temperature range for the solenoid! Solenoid Size Materials Housing: Aluminium ematal coated Seals: Nitrile-butadiene rubber (NBR) Spool: Aluminium altef coated Internal parts: various materials General: non ferrous metal free End plugs: brass nickle plated Operating life > million switchings Mounting position Any position Mounting options Pipe installation interface NPT connection thread On request Manual override Upon request the valves listed in the type overview are available in models with push-buttons for manual operation. The type description changes as follows: Example without manual override: Type CP 06 CNE oh Example with manual override: Type CP 06 CNE DK Thanks to robust design, long and reliable operation can be guaranteed. Type of protection EEx i The valves listed in the type overview correspond to the models for solenoids in the type of protection EEx me or standard type with. W. In the type of protection EEx i they receive an additional designation: Example with solenoid. W: Type CP 06 CNE oh Example with solenoid in EEx i: Type CP 06 CNE oh i Adapter with filter In order to prevent solenoid valve failure we offer an adapter filter in our product line. The built in sieve, with mesh width 0. mm, filters dirt particles and can be easily cleaned or replaced. The adapter has a G straight male thread with O-ring seal (NBR) and is available with G or NPT connection thread (see Fig. ). G NPT Order No G G Order No G NPT Order No G G Order No Exhaust protector IP6 Suitable for solenoid valves with connection and integral spring chamber ventilation. The spring chamber of the actuator and the solenoid itself are protected against the penetration of agressive ambient air or rain by the non-return system. Functional reliability and operating life are thereby increased. Order No (see Fig. 6) Solenoid valve for universal application New and unique, with integrated automatic shuttle valve. A universally applicable solenoid valve for all applications with : Type CP 06 CPU oh with interface and threaded port connections is usable on linear actuators as well as quarter turn actuators, without modifica-tion. With the mounting plate, available as an accessory, the valve can be mounted and encased in on the rib. EMATAL - Corrosion protection Eugen Seitz AG aluminium valves are "hard ematalised" as standard. Ematal is a surface treatment in which a very hard and compact aluminium oxide layer with titanium oxide intercalation is applied to the valve. This produces a long-lasting protection against corrosion and mechanical stress. For detailed information with an overview of the chemical resistance please request the "Hard ematal surface treatment for solenoid valves" technical information.

3 interface For quarter turn actuators The interface allows solenoid valves to be screwed simply and directly onto the quarter turn actuator. Timeconsuming, complicated assembly is no longer necessary. A grub screw guarantees that the established initial position cannot be changed by simply turning the valve. Tapped recess M, M x depth mm tief mm For actuators with linear movements Solenoid valves with the interface for actuators with linear movements are mountable directly on position regulators and signal devices of linear actuators with the corresponding interface without a connecting plate. The control signal of the positioner leads by the solenoid valve through the additional pressure connection on the flange area. Connection supplies the necessary control air. flow control plate An intermediate flow control plate is available as an accessory for the / way and / way valves with interface. Order no (see figure ) Order no (see figure ) connection plate A connection plate for direct mounting on the rib of diaphragm actuators is also available as an accessory.
