JOEPAI focuses on the production, research and development, design, sales and service of ball Valves, globe valves, check valves, butterfly valves, and filters. Modern industrial piping systems demand far more from valves than simple cut-off and flow control. The Mounting Pad 3PC Flanged Ball Valve is engineered for applications requiring frequent on-off cycling, automated integration and low maintenance costs. Whether deployed in oil & gas pipelines, chemical processing plants or power plant cooling water circuits, this ball valve delivers reliable, safe fluid control solutions.
Pressure Class: PN16–PN40 (Class 150–300)
Temperature Range: -20°C to +200°C (with PTFE seats)
Mounting Platform: ISO 5211 compliant for direct actuator mounting
Bubble-Tight Zero Leakage Sealing:Our Mounting Pad 3PC Flanged Ball Valve features PTFE seats paired with a self-adjusting preloading structure. It maintains bubble-tight shutoff even after 10,000 open-close cycles. For steam lines with frequent actuation, its 90° rotary stroke completes full opening or closing within 2 seconds, perfectly matching automated production lines requiring rapid response.
Low Operating Torque:The ball of this 3PC flanged ball valve undergoes mirror polishing (Ra ≤ 0.4μm), cutting operating torque by 25% compared to standard surface finishes. This allows customers to specify smaller actuators, lowering procurement costs and operational power consumption.
Anti-Blowout Stem Design:The valve stem is fitted with dual O-ring seals and a live-loaded packing assembly to effectively prevent leakage of hazardous media. An anti-static device is installed between the stem and ball to guarantee safe operation with flammable and explosive fluids.
User-Friendly Maintenance Structure:Built with a three-piece body design, the 3PC flanged ball valve enables on-site internal cleaning, seal replacement and component inspection without removing the entire valve from the pipeline, drastically reducing downtime.
Boasting superior sealing performance and seamless automation compatibility, the Mounting Pad 3PC Flanged Ball Valve is widely adopted across the following sectors:
Power Plant Cooling Water Systems: Corrosion-resistant and zero-leakage, ideal for circulating water and closed cooling loops
Chemical Skid-Mounted Equipment: Optional CF8M construction resists chlorides and corrosive chemical media
Natural Gas Metering Stations: Low torque design works well with pneumatic/electric actuators for remote regulation
Food & Pharmaceutical Pipelines: Easy on-site cleaning, complying with hygienic process standards
Body material selection directly determines the service life and safety of the ball valve under specific working conditions:
Body & End Caps:WCB Carbon Steel (for water, air, steam ≤200°C) / CF8 (304 Stainless Steel, for weak acid and general chemicals) / CF8M (316 Stainless Steel, for chloride-containing media and seawater)
Ball:SS304 / SS316 (Standard) / SS316L Low-Carbon Grade (resists intergranular corrosion post welding)
Seat:PTFE (Standard, -20~200°C) / PPL High-Temperature Grade (-29~280°C) / PEEK Reinforced Grade (customized only)
Flange Standard: The Mounting Pad 3PC Flanged Ball Valve comes standard with ANSI B16.5 Class 150 drilling patterns; other standards including DIN, JIS and PN are available upon custom request.
Actuator Sizing: For pneumatic or electric actuator configurations, verify the actuator output torque matches the valve’s operating pressure. Customers are advised to provide medium pressure, nominal diameter and switching frequency. The JOEPAI technical team can offer accurate sizing calculation support.
