CERA SYSTEM
Verschleißschutz GmbH

The CeraValve type KSV is a ceramic lined ball valve for the open / close function as well as for trottling control applications for use in excessively abrasive and corrosive applications. The basic principle of this valve is based on a floating ball sealing against the downstream seat, using differential pressure as sea-ling force. Both seats are fixed while the ball has a predetermi-ned “float space”. The ceramic components of the valve are held within the metal housing which absorbs the physical load and vibration of the pipe system. The ¼-turn movement of the ball (0-90 °) yields a specific valve opening. The ball slot is available in in several different geometrical shapes depending on the desired flow characteristic for the application. The three piece design of the valve allows for direct connection to existing pipelines without the need for pipe reducers in front and behind the valve. For example, the valve can be configured with 3.0˝ flanges with a 2.0˝ center body. The end flanges accommodates the direct mount to the 3.0˝ pipe while the reduced (2.0˝) center body provides for optimum selection of installed valve trim and also reduces weight and costs of the valve and installation. Actuator connection is done by a yoke interface that meets the dimen-sional standards of ISO 5211. This provides for a direct center of most all ¼ turn actuation including, pneumatic, electric, and hydraulic actuators. 10 position locking manual hand levers and manual gear operators are also available. The yoke interface is removable and able to be easily modified to accommodate special applications.

CERA SYSTEM develops and produces customer-specific ceramic precision components in small batch sizes through to series production for the most diverse areas of application. Focal points are sealing and control discs for air conditioning, sanitary fittings as well as many other applications. Ceramic components for the sensor, food engineering and building services sectors round off our portfolio.

The SDL-type valve is a sliding disc valve with a ceramic sealing system for open/close function, for use in highly corrosive and abrasive media.The valve is designed for extreme conditions, where high switching frequencies and a long service life are required, but dead space cannot be permitted inside the valve.Control functions can be realised using a switching frequency control system.The medium comes into contact not only with the ceramic discs, but also with housing parts and seals. Alongside the standard solutions, other material combinations are possible, depending on operating conditions.This slide valve type is designed for very small volume flow rates in the nominal width range from below 1 mm up to 10 mm. Pressures of up to 250 bar / 3600 psi are permitted here.The connections are designed with internal threads as stan-dard. Other connection variants are possible.The functional principle is based on three floating ceramic discs that seal against each other. The middle disc shifts linearly, while the two outer discs are stationary.Opening and closing take place through the vertical displacement of the middle disc.The valves are supplied both with a T-handle and prepared for attachment to a drive unit. All customary actuators can be used as drive units. As standard solution, the slide valves are offered with electromagnets, with linear stepping motors and with pneumatic cylinders.The actuator is mounted by means of a yoke and adapter arrangement. Special connections are possible.

The SSC-type valve is a sliding disc valve with a ceramic sealing system for open/close function and control tasks, for use in highly corrosive and extremely abrasive media. It is designed for extreme conditions, where either high switching frequencies and a long service life are required, or where severe abrasion occurs in the control position but dead space cannot be permitted inside the valve.The functional principle is based on three floating ceramic discs that seal against each other. The middle disc shifts linearly.Different geometric shapes of disc apertures permit specific control characteristics. The two outer discs are stationary. Springs are used to compress the sealing system.The medium only comes into contact with ceramic components and seals, so that special materials are not normally required for the housing.
