Ramén KS-1C

Ramén KS-1C

Material Execution 1C
– Metal seated ball sector valve with seat holding ring hard chromed DN 25 – DN 300

The Ramén Ball Sector Control Valve in material execution 1C has a lapped and hard chromed ball sector sealing surface together with a metal seat ring. KS-1C has an additional and increased protection against abrasion. The surfaces at the valve inlet i.e. the seat holding ring and it’s surfaces, where the metal seat ring is located, are hard chromed for extra protection and extended life time of the valve parts and surfaces that are subject to the highest fluid velocities when valve is in throttling position.

KS-1C is used for abrasive liquid or gas at moderate pressure or pressure drop (flow velocity) and temperatures. KS-1C is often installed in reverse flow direction with the ball sector orifice located at the valve outlet so that the valve body does not suffer from the high fluid velocity after the throttling orifice.

We recommend other material executions in case of high velocity and/or temperature and if cavitation will occur. Optional O-ring seals and trim variations are available, please consult Ramén. Always consult Ramén for valve sizing and material selection. General technical bulletins and data sheets are available for complete technical specification. Do not hesitate to contact Ramén for clarification.
