Lined Standard ASME/ANSI Ball Valves Reliable body and seat sealing Fields of application The design of the ball valves series BVA is based on more than 30 years of application experience with lined ball valves. They provide an excellent ratio of economic and operational performance in a wide variety of process applications. The Richter ball valve BVA is designed • as shut-off and automated valves for corrosive and hazardous media, • where stainless steel, special metals, PVDF etc. are not sufficiently corrosion-resistant, • as alternative to valves made of exotic special metals and • serve...

RICHTER Innovative cone shape stem seal design The PTFE packing insert translates a low axial thrust into a higher radial sealing force by means of the law of cone. The packing gland is designed with a diameter as small as possible. The result: outstanding stem seal performance under the most challenging conditions, permanent preload controlled manual adjustability at any time. An added benefit is the ability to monitor the live loaded condition of the stem seal simply by inspecting the “gap” between the packing followers, thus lending this de- Stem seal design Faxial Spring...
