TA 170 – 1 safety valve
Dimensions: ∅ 210 mm, height 210 mm Stricter requirements for the sterility of pure water mean that pure water containers must be hermetically sealed and ventilated using an air filter system. If built-in filters and control devices fail, the TA safety valve reduces the negative or positive pressure from large-volume, closed water basins when a certain pressure is reached by opening the suction or pressure side. The valve then closes automatically and the system remains ready for operation. Optionally, the safety valve can be equipped with inductive proximity switches to indicate a response in the control room. The response pressure is set at the factory and is stated on the nameplate. The TA safety valve is made of high-quality aluminum and coated on the outside in red RAL 3000.
- Maximum building protection
- Securing the air filter system
- Absolutely maintenance-free
