Ball Valves
Metal-seated trunnion-mounted ball valve
This series is listed for high-pressure isolation, with a metal seat option. Suitability for temperature, solids, cycling and shutoff depends on the proposed construction and documented test scope.
About the metal-seated trunnion-mounted ball valve manufacturerThese are family-level options. Confirm the offered series rating and materials against its approved datasheet.
TRUNNION BALL VALVE PROCUREMENT
What should a metal-seated trunnion ball valve RFQ confirm?
Specify the ball and seat trim, any required surface treatment, service conditions, maximum differential pressure and seat-test acceptance for a metal-seated trunnion ball valve. Confirm the exact bore, end connections and actuation scope on the offered datasheet. Neither the body pressure class nor metal seating alone qualifies the valve for the intended duty.

- Define medium, solids, normal/design temperature and pressure, maximum differential pressure, cycling duty and shutoff direction with units.
- State ball and seat trim requirements, any required surface treatment and the applicable leakage test and acceptance level. Request the offered construction and pressure-temperature limits in writing.
- Specify DN or NPS, bore, flange or weld details, maintenance envelope and manual or actuated operation requirements. Confirm torque and actuation scope for the actual differential pressure and service.
- For an automated package, provide minimum available air pressure or electrical supply, controls, fail position, operating time, cycle frequency and hazardous-area requirements. Confirm which actuator and accessories are included in the offer.
- State manual, geared or actuated operation and the required operating time and supply for review. Provide quantity, delivery destination, requested date and drawing, traceability and inspection requirements. Request a quotation deviation list; do not treat the largest catalogue size, pressure and temperature as a single available combination.
Sample catalogue reference
The figures describe the named catalogue construction. Size, pressure, temperature, material and end options are not interchangeable combinations; the maximum values do not apply simultaneously. Confirm the offered configuration, seat/seal compatibility, pressure–temperature limits and dimensions on its approved datasheet and drawing. The listed ranges summarize catalogue sizes, not every intermediate DN.

These are model- and class-specific examples. Not every size or end style is available in every configuration; final dimensions and ratings require an approved drawing and datasheet.
SERIES SELECTION
Metal-seated trunnion-mounted ball valve: selection and RFQ checklist
Assess the trunnion arrangement and metal-seat test requirements together.
Compare construction choices in this valve family- Define operating differential pressure, temperature, solids and cycling duty.
- Confirm ball and seat materials, sealing direction and cavity-pressure handling.
- Agree the leakage test conditions and review torque before selecting an actuator.
