MBV Metering Ball Valve Series

Product catalog summary
Overview
The MBV Series Metering Ball Valves are designed for precision flow control in moderate pressure applications. They offer a unique shut-off capability and allow for fine regulation with up to 11 handle turns. The series includes three precision stem tapers for metering at flow capacities as low as CV=0.001.

General Features
  • Materials: Stainless Steel, Fluorocarbon FKM, Nylon with Glass Fiber.
  • Lubricants: Silicone-based and PTFE.
  • Operating Pressure: MAWP 2000 psi (137 Barg).
  • Operating Temperature: MAWT 300°F (150°C).
  • Size Range: 1/8" to 3/8" & 3mm to 6mm.
  • End Connections: LET-LOK®, FNPT, MNPT, Male Face Seal.
  • Stem Taper Options: 1°, 3°, and 5° for flow control.

Design and Construction
  • Encapsulated ball stem design minimizes system contamination.
  • Double O-ring sealing ensures leak-tight operation.
  • Stem diffusion surface hardening for resistance to wear and corrosion.
  • Factory calibrated set screw for stem tip protection.

Dimensions and Specifications
  • Various dimensions provided for different end connections and stem taper angles.
  • Flow coefficients and handle turns detailed for MBV-H, MBV-F, and MBV-X series.

Testing and Performance
  • Tested for bubble-tight shut-off at 100 psig differential pressure.
  • Factory tested with Nitrogen at 1000 psig for leakage through the seat.
  • No detectable leakage allowed during shell test.

Technical Data
  • Pressure-Temperature Ratings: Up to 2000 psi and 300°F.
  • O-ring Materials: Fluorocarbon FKM, Buna N, Ethylene Propylene, Perfluor, Polychloroprene.

Ordering Information
  • Options for metering type, body and ends material, end connection type, handle options, and treatments.
  • Warning: Proper selection, installation, and use are crucial to prevent damage or injury.

FLOW SETTING The H, F and X Series metering ball valve designs were tested for proof and burst. MBV-H series metering valve is tested for bubble tight shut-off at 100 psig (6.8 bar) differential pressure. Every MBV - H, F & X metering valve is factory tested with Nitrogen at 1000 psig (69 bar) for leakage through the seat. No detectable leakage is allowed during shell test. MBV-F series metering valve handle dead stop is set at 4 to 10 std cm3/min with 5 psig (0.34 bar) inlet pressure. MBV-X series metering valve handle dead stop is set at 4 to 10 std cm3/min with 15 psig (1.0 bar) inlet pressure....
