Threaded Ball Valve 3-PC Stainless Steel 2000WOG

Key Features

• Three-Piece Serviceable Construction: A central body connects to two end sections, supporting access to the ball, seats and joint seals. Removal of the centre section while the ends remain installed depends on the confirmed design and available clearance.
• Carbon-Filled PTFE Seats: The published configuration uses CPTFE seating. Confirm the compound specification and its pressure–temperature limits when assessing the intended fluid and operating cycle.
• Full-Bore Passage: The ball opening aligns with the pipeline when fully open, helping limit obstruction and pressure loss across equipment connections.
• Rotary On/Off Operation: A quarter-turn movement provides convenient isolation for manual operation or a suitably selected automated assembly.
• BSPP Female Threads: The end specification references ISO 228 parallel threads. Correct mating geometry and a defined sealing arrangement are essential to a pressure-tight installation.
• Automation and Operating Components: The published construction includes an ISO 5211 mounting interface, locking device and anti-static device. Confirm actuator torque, stem coupling and any required continuity testing for the application.

Materials and Construction

• Body, End Caps and Ball: Listed stainless steel options include CF8, CF8M and CF3M.
• Stem and Gland: Stainless steel.
• Ball Seats: Carbon-filled PTFE.
• Joint Gasket: PTFE.
• Stem Sealing: The material schedule lists RPTFE, PTFE, glass-fibre-filled PTFE and a Viton O-ring.
• Listed Fasteners and Handle: Stainless steel.

Confirm the complete sealing arrangement and individual component grades for the ordered configuration.

Pressure Rating by Size

The published range covers DN15–DN100:

• DN15–DN25: 2000 WOG.
• DN32–DN50: 1500 WOG.
• DN65–DN100: 1000 WOG.

Confirm the permissible working pressure at the actual operating temperature. WOG ratings do not establish a steam-service rating or suitability for every gas.

Seat materials, O-rings, packing and joint seals can limit the operating envelope. Provide the medium, temperature, maximum differential pressure and cycling frequency when requesting selection assistance.

Typical Applications

• Industrial Utility Systems: Compatible water, oil, air and gas lines requiring threaded isolation.
• Pump and Process Packages: Equipment connections where pressure capability and maintenance access are important.
• Chemical Handling: Selected services supported by a verified stainless steel grade and complete seal-compatibility assessment.
• Oil and Lubrication Circuits: Compatible duties after checking viscosity, additives and temperature.
• Automated Equipment: Local or remote isolation using an appropriately sized actuator.
• Selected Steam Duties: Applications covered by confirmed steam-service pressure–temperature data and suitable seals.

Installation and Maintenance

ISO 228 threads provide mechanical engagement. A pressure-tight connection requires the specified sealing surfaces and an appropriate seal outside the threads. Confirm the complete joint design rather than assuming interchangeability with tapered-thread fittings.

Support and align the pipework, and apply installation force at the designated wrench flats. Allow clearance for handle travel, body-bolt removal and servicing.

Before dismantling, isolate, depressurize, drain and cool the assembly as required. Inspect sealing surfaces, install specified replacement parts and follow the approved tightening sequence. Verify operation and leakage performance before returning the valve to service.

Use the valve primarily for on/off isolation. Sustained throttling, abrasive particles and crystallizing fluids require additional assessment.
