Flow-Tek's series RF15 flanged ball valves feature a compact, 1-piece body design with threaded insert. The 1-piece body supplies maximum structural strength while minimizing the number of potential leak paths. A floating ball design offers low torque and increases valve cycle life. These rugged, economical, end entry flanged ball valves are ideal for industrial applications.

Flow-Tek's series RF15 flanged ball valves feature a compact, one piece body design with threaded insert. The one piece body supplies maximum structural strength while minimizing the number of potential leak paths. A floating ball design offers low torque and increases valve cycle life. These rugged, economical, end entry flanged ball valves are ideal for industrial applications. Non-Fire safe and API 607 4th edition fire safe valves are available as non-fire safe with standard stem seals or fire safe to API 607 4th edition with graphite stem seals. Secure mount series RF15 valves offer ease of automation due to an integrally cast actuator mounting pad that complies with ISO 5211 through 2 IN valve sizes.

• Series RF15 1 - 2 IN valves feature live-loaded, self- adjusting primary and secondary sealing. Utilizing belleville washers, the stem seal automatically adjusts to compensate for changes in temperature and normal wear. 3 - 12 IN valves utilize an independent packing gland which can be easily adjusted without removing mounting hardware or operator. The packing gland is contoured to more uniformly distribute the load across the packing
• Flow-Tek balls are precision machined and mirror finished for bubble-tight shut off and less operating torque. As an added safety feature, a hole in the stem slot of each ball equalizes pressure between the body cavity and the line media flow
• 1 - 4 IN valve bodies are investment cast and all valve size castings are solution annealed/normalized for the highest quality and added strength. All body castings are marked with a foundry heat number for full traceability
• Flow-Tek's seat design ensures bi-directional, bubble-tight sealing with low operating torque. All resilient seats feature relief slots or seat O.D. clearance to relieve pressure past the upstream seat and provide positive preloading to ensure low pressure/vacuum sealing
• All RF15 valves have anti-static device as standard. These devices positively ground ball and stem
• All manually operated valves feature a locking device to prevent accidental movement of ball position
• Series RF15 valves offer ease of automation due to an integrally cast actuator mounting pad that complies with ISO 5211 through 2 IN valve sizes
• Flow-Tek manufactures heavy duty, high quality stems with double "D" connection to ball and operator mounting. Stem and ball design ensure positive contact. All Flow-Tek stems are internal entry and blowout proof for maximum safety
• Flow-Tek's interchangeable family of valves feature strong, large diameter stems with live-loaded, self-adjusting sealing utilizing belleville washers which automatically adjust to compensate for changes in temperature and wear. Manual adjustments which can cause damage to the seal and seat are not required. The assembly is secured by a saddle-type lock washer which prevents stem nuts from unthreading in high cycle automation applications (valve sizes up to 2 IN)
• An adjustable v-ring design creates a multiple seal between the stem and body. Each stem assembly is composed of three or four (dependent on valve size) rings providing a very high cycle life by resisting creep and cold flow. The thrust washer and the thrust washer protector combine to provide a primary seal, reduce torque and prevent galling. This arrangement is a Flow-Tek exclusive

Application: Process, Tank Farms, Fueling, Oil and Gas
