Technical Insight: 2000 WOG 2-Piece High Platform Ball Valve - Design Features & Application Environments

The medium-pressure outlet pipelines of a city gas pressure regulating station operate at a design pressure of 4.0 MPa. The system requires integration with a SCADA system for remote dispatch and emergency shut-off. Valves must provide zero external leakage, long maintenance-free intervals, and support in-line servicing to avoid disrupting gas supply to the district.

2000 WOG 2-piece high platform ball valves in CF8 (304 stainless steel) with NPT threaded ends and RPTFE reinforced seats were selected, fitted with direct-mounted explosion-proof electric actuators. The valve's pressure rating far exceeds actual operating pressure.

• The valve body and seals operate under long-term low-stress conditions, greatly reducing seal creep. Service life is extended by more than 50% compared with standard PN40 ball valves.
• The ISO 5211 standard high platform enables direct actuator mounting without adapter brackets, cutting installation time by 30% and ensuring higher coaxiality for stable remote control accuracy.
• The 2-piece split body design supports in-line disassembly and seal replacement without cutting the pipeline, reducing district maintenance downtime by 70%.
• Floating ball bidirectional sealing structure delivers zero external leakage, ensuring safe gas transmission and complying with urban gas design specifications.

The high-pressure branch of a circulating cooling water system in a large refinery operates at 2.5 MPa, with intermittent water hammer shocks in the pipeline. Original standard PN25 ball valves suffered frequent seat leakage and body deformation, and required pipeline cutting for maintenance which caused production shutdowns.

Replaced with 2000 WOG 2-piece high platform ball valves in WCB carbon steel, featuring full port flow paths and paired with pneumatic actuators for programmed on/off control.

• The 2000 WOG heavy-duty valve body offers far superior water hammer resistance than standard PN25 valves, withstanding instantaneous water hammer up to 10 MPa without body deformation or seal failure.
• Full port design creates pressure loss of less than 0.03 MPa, reducing circulating pump load by 5% and delivering notable long-term energy savings.
• Direct-mounted pneumatic actuators on the high platform respond in less than 1 second, suitable for frequent programmed switching operations.
• The 2-piece valve body allows quick disassembly for cleaning scale and debris from the ball core, doubling maintenance efficiency without pipeline cutting or production shutdown.

Screw-type water chillers in a large commercial complex use R134a refrigerant, with main lines operating at 1.8 MPa. Valves are required to have excellent sealing performance to prevent refrigerant leakage, and be compatible with electric actuators for group control via the building automation system (BAS).

2000 WOG 2-piece high platform ball valves in CF8 stainless steel, with specialized refrigerant sealing seats and direct-mounted compact electric actuators.

• High-pressure rated valve body with precision sealing achieves zero refrigerant leakage, eliminating cooling capacity loss and environmental emission issues.
• Standardized ISO 5211 high platform interface improves chiller batch assembly efficiency by 30%. Actuators are universally interchangeable without custom adapters for easier after-sales replacement.
• The 2-piece structure facilitates disassembly and maintenance during major chiller overhaul without damaging pipeline welds, reducing maintenance costs by 40%.
• Operating pressure far below the nominal rating slows seal aging significantly, extending the maintenance-free interval to over 3 years.

A surfactant raw material transfer line in a daily chemical plant operates at 1.6 MPa, with mildly corrosive media. Valves must support remote control, be easy to disassemble and clean, and meet hygiene requirements for batch changeovers.

2000 WOG 2-piece high platform ball valves in CF8M (316 stainless steel) with full port design, PTFE seats and explosion-proof pneumatic actuators.

• 316 stainless steel body resists mild corrosion. Full port design has no flow dead zones, reducing material buildup and deterioration to meet daily chemical production hygiene requirements.
• Long-term low-stress operation under derated conditions eliminates media permeation risk and cross-contamination between batch changeovers.
• Direct-mounted explosion-proof pneumatic actuators on the ISO high platform directly meet chemical workshop explosion protection requirements without additional modification.
• The 2-piece split design allows quick disassembly for internal cleaning and sterilization, reducing batch changeover cleaning time by 60%.

The high-temperature Clean-in-Place (CIP) system in a beverage manufacturing plant operates at 3.0 MPa, with 80°C alkaline cleaning agents. Valves must be temperature and corrosion resistant, provide reliable sealing, support automated program control, and comply with food GMP standards.

Food-grade 2000 WOG 2-piece high platform ball valves in CF8 stainless steel, fitted with RPTFE reinforced high-temperature seats and direct-mounted sanitary pneumatic actuators.

• 3.0 MPa operating pressure is far below the 2000 WOG nominal rating, providing ample pressure reserve even at elevated temperatures, with no risk of seal failure or body deformation.
• RPTFE reinforced seats offer superior temperature and chemical resistance, with twice the service life of standard PTFE seats, enduring continuous scouring by high-temperature cleaning fluids.
• High platform direct-mount design creates no hygiene dead zones at the actuator-valve interface, easy to clean and disinfect, fully compliant with food industry GMP certification requirements.
• The 2-piece valve body allows quick disassembly for internal cleanliness inspection without removing the entire pipeline, simplifying routine inspection and maintenance.
