The SV 26 is a compact mechanical float valve designed for small tanks and installations with limited space. Level adjustment is achieved by repositioning the float along the lever arm. No electrical level sensor or actuator is required for operation.
SV series is intended for water and neutral, non-viscous liquids. For potable water, refer to RSV O series as per datasheet; SV 26 should not be specified for drinking water applications without certification verification for each use case.
SV 26: Brass, DN 10–DN 15, NBR, max 100 °C. SV 45: Stainless steel 1.4404, up to DN 20, FKM, up to 190 °C. SV 94 MS: Brass, lower Kvs at DN 10.
When is SV 26 selected?
For low fill rates, threaded connections, and neutral, non-viscous liquids.
What should be checked before installation?
Inlet pressure, required flow rate, temperature, float material, installation position, and unobstructed lever movement.
SV 26
Float valves of this series are ideal for filling small storage tanks or for level control. A desired liquid level can be precisely set by moving the float.
Nominal size DN 10 up to DN 15
Inlet pressure up to 12 bar
Kvs-value 0.3 m³/h
Temperature range up to 100 °C
Technical data
CE-certification according to the European Pressure Equipment Directive is mandatory for numerous products and delivery areas. Other certificates, however, are certificates of individual quality, such as DVGW and DIN EN ISO 9001, which stands for the internal quality management system with its extensive functional and performance checks. The particularly strict regulations of the national rules and regulations guarantee the highest possible safety - especially when it comes to the reliability in your plant.
