RMA has meanwhile become one of the leading manufacturers of fully welded steel ball valves which are world-wide in use. For high pressure ranges the sealing system "primary metal and secondary soft sealing" is used, which makes possible an optimum function in ranges up to 150 bar. This sealing system consists of two metal sealing planes (chrome steel) and a flexible soft sealing ring (PTFE/carbon). Of course, these ball valves offer the "double block and bleed"-function. Proof of sealing is provided in both end positions, even under maximum operating pressure using a special bleed nipple or, if required, using drain and vent pipes with an additional ball valve. |
