Valworx 551512C stainless steel 3-piece ball valves are designed for use with water, air, oil, and other media compatible with the materials of construction. Unique three piece investment cast bolted body design offers the advantage of a swing out body for easy inline maintenance. Low operating torque with quarter turn latch-locking handle. Removing handle allows for easy mounting of electric or pneumatic actuators with the industry standard ISO5211 direct mounting pad. This ensures precision shaft alignment and eliminates the need for additional brackets and couplings. Triple stem seal design is live-loaded and self-adjusting, compensating for wear, pressure, and temperature fluctuations. All valves are tested per API 598.
