SSV Safety Shut Down Units

SSV Safety shut down units, DVGW certified in accordance with DIN 14382 The ideal SSV system for pipeline safety requirements The Fahlke SSV safety shut down unit is currently the only available SSV unit which has been tested and approved in accordance with the latest certification guidelines, DIN 14382, of the German Certification Center, DVGW, in combination with a ball valve. With the most modern SSV on the market, Fahlke offers ideal protection against overpressure in the pipelines being monitored. Compared with other outside products, the Fahlke SSV unit saves you significant pipelines and operating expenses. What makes the difference? Where are costs saved? Because of their full passage when open, Fahlke SSVs can also be scraped without the need for constructing expensive bypass lines. The Fahlke SSV unit is equipped with two independent seals. As most conventional SSV units are only equipped with a single seal, this saves expenses with regard to the required installation of two SSV valve units. All Fahlke SSV units can also be employed for standard open and shut operations. The employment of the most up-to-date temperature compensation AG1 pilot valves in the controller make approaching your pipelines maximum pressure possible in the first place, thus allowing the maximum utilization of your line’s throughput rate. The Fahlke SSV unit is available as either a double block or bleed type unit and can be tested for proper function in either the open or closed position. In compliance with the EN 14382 safety guideline, Fahlke SSV actuators provide five times the torque required for normal valve operation up to a predefined nominal diameter. SSV sizes and pressure ranges Valve actuator design The SSV control design Test environment: hot/cold chamber (test temperature between -60°C and +80°C) Fahlke has its own hot/cold chamber to test valve actuators under extreme operating and temperature conditions.
