Designation : Standard ball valve with one-piece ball/stem unit or ceramic ball and stem, with plastic coating, cone shape stem sealing, seat rings of pure PTFE, cavity reduced as standard feature, twopiece body.

Series:                  GKV225A/FVersion with lockable lever or  hand gear GKV225AP/F→ Design prepared for pneum., hydr. or electric actuator to ISO 5211 Certified to Clean Air Act (TA Luft) Strength and tightness (P10, P11) of the pressurebearing body tested to DIN EN 12266-1. Gas-tight (P12) in the seat to DIN EN 12266-1,  leak rate A MSS SP 25 Standard Marking System MSS SP 72 General Service API 598 Valve Inspection and Testing The tests at Richter fulfils the requirements  of API 598 on principle. However this  standard contains optional, additional tests.  These tests are not object of the tests at  Richter and have to be arranged by order  with Richter (e.g. point 3.3: High Pressure  Closure Test). Face to face: ASME B16.10, Class 150 column 19 Flange connecting dimensions:  ASME B16.5 Class 150, raised face.
