Technical Datasheet -- V-Port Segmented Ball Control Valves for High-Capacity Throttling
V-port segmented ball control valves for high-capacity throttling and on-off service. V-notch ball profile provides shearing action for slurry and fibrous media while maintaining precise flow control with 100:1 to 300:1 rangeability. SS316 or WCB body with pneumatic rack-and-pinion, scotch-yoke, electric, or hydraulic actuator. Smart digital positioner with HART / Fieldbus / Profibus and valve diagnostics. ISA S75 / IEC 60534 compliant.

The Rotary Control Valve -- V-Port Ball SS316 is designed, manufactured, and tested in accordance with applicable API / ASME / BS / ISO international standards. Compliance documentation and Material Test Certificates (EN 10204 3.1) are provided with every order.
Standard construction is carbon steel, stainless steel (CF8 / CF8M), and special alloy grades. Alternative and upgraded grades -- Duplex, Super Duplex, Inconel, Monel, Hastelloy, and NACE MR0175 trims for sour service -- are available on request.
It is offered in a range of sizes as per the technical specification with standard ANSI / ASME pressure classes (PN ratings on request). End connections include flanged (RF / RTJ), butt-weld, socket-weld, and screwed ends as per specification.
Yes. Supreme Valves India is an established exporter of industrial valves to Saudi Arabia (KSA), the UAE, Qatar, Kuwait, Oman, Bahrain, and across the Gulf. We provide sea-worthy export packing, EN 10204 3.1 / 3.2 certification, certificate of origin, and support for SABER / SASO conformity on KSA shipments.
Every valve undergoes hydrostatic shell and seat testing per API 598 / ISO 5208. Documentation includes EN 10204 3.1 MTC (3.2 on request), NDT reports, and fire-safe (API 607) or NACE MR0175 certification where applicable. Third-party inspection by TÜV, SGS, Bureau Veritas, or Lloyd's Register can be arranged.
Order quantities are flexible -- from single units for stocked items to bulk volumes for project requirements. Lead time depends on size, material, and quantity; please contact our team with your specification for a firm delivery schedule and quotation.
