Compact Ball valve is a manufacturer standard design suitable to combine a compact ball valve design with robustness and reliable performances. The valves do not rely on lubricant or grease to assist sealing between the ball and seat also when metal-to-metal sealing is used. The valve design is based on trunnion mounted or support plate configuration in order to get the operating torque as lower as possible.
