The robust design of the nipples ensures high operational safety with minimum maintenance. The high-quality materials used ensure very good acid resistance and the precise manufacturing ensures a long service life of the nipples. The nipples are connected directly to the water pipe (max. 6 bar). The flow rate can be regulated from the outside with an adjusting screw. Due to computer-controlled production, theese is always in alignment with the actuating lever. This ensures that access to the adjusting screw is always from above.
