Maximize the functionality of your ball valves with pneumatic or electric actuators. Thanks to ISO 5211 mounting flanges, spindle extensions and mounting bridges, our valves are easy to automate – for precise control in industrial plants.
Increase the user-friendliness of your ball valves with stem or stem extensions. This modification is ideal for isolated valves or valves that are difficult to access and enables convenient manual operation or the connection of pneumatic and electric actuators.
For all our ball valves – whether with or without heating jacket, whether in manual mode or automated by actuators – we offer the right insulation, individually manufactured.
Insulation can be implemented with the high-quality IFS-Plast25 insulating jackets and insulating pads, for example. This solution ensures optimum energy efficiency and safety in your process.
KSL is designed for liquids such as oil and water, KSN for gas applications with DVGW approval.
DIN EN 558, ISO 5211, PED, TA-Luft, LABS-compliant; KSN also DVGW gas and HTB tested.
Yes, both series have an ISO 5211 mounting flange for electric or pneumatic actuators.
KSL: -20 °C to +180 °C, KSN: -20 °C to +60 °C.
Yes, both series are fire-safe to international standards as standard.
Our insulations are more than just accessories – they perfectly complement fittings and systems and increase efficiency, safety and adaptability.
