BALL VALVES

D-Valve Engineer’s ball valves are completely in-house designed, manufactured; quality and pressure tested meeting international standards such as ASME, API, ISO etc. Our Customers have the choice to select Single piece or Two piece or Three piece construction in Floating design and Two piece or Three piece in Trunnion Mounted design based on their application. Our ball valve pressure ranges are from Class 150# to Class 2500#. We offer our customers a wide selection of materials for Body/Cover, Ball, Stem, Soft and Metal seats, and Seals for the right application.

D Valve Manufacturing Fire Safe Ball Valves compliance with API 607. If the primary soft seat is damaged or misplaced due to fire, the secondary metal lip provided in the Body and Cover will prevent the leakage to meet API 607 requirements.

Cavity pressure building in any ball valve may affect the performance of the valve and reduce the seat life. All our floating ball valve seats have pressure relieving slots that prevent the building up of pressure in the cavity and relieve the cavity pressure to the upstream side of the seat. The same fluid pressure is maintained in the upstream, body, and ball cavity.
