Technical Datasheet -- Steam Jacketed Valves for Solidifying Media Service
Fully steam-jacketed gate, globe, and ball valves for molten sulphur, bitumen, pitch, and other solidifying media. Inner body carries process fluid; outer welded steam jacket (SA-516 plate, full-penetrement welds with PWHT per ASME Section IX) maintains temperature above solidification point. Flanged steam inlet/outlet connections positioned for thermosyphon or forced circulation. Inner valve uses standard API 600 / API 6D proven trim and seats. WCB, SS316, or WC6 inner body with Stellite seat overlay. Jacket rated for 10 bar saturated steam. ASME B16.34 / API 600 / API 6D / ASME Section IX compliant.
| Parameter | Specification |

| Product Type | Jacketed Valves |
| Category | Specialty Valves |
| Size Range | 1" to 12" (DN25 to DN300) |
| Pressure Rating | PN16 / PN25 / PN40 / Class 150 / Class 300 -- steam jacket rated for 10 bar (145 psi) saturated steam typical |
| End Connections | Flanged RF per EN 1092-1 PN16/PN25/PN40 / ASME B16.5 Class 150/300 -- process side; Flanged RF or threaded NPT -- steam jacket inlet/outlet |
| Inner Body Material | ASTM A216 WCB (standard) / ASTM A351 CF8M (SS316, for corrosive or high-temp service) / ASTM A217 WC6 (high temperature > 425 deg C) |
| Jacket Material | ASTM A216 WCB / ASTM A351 CF8M (SS316) / SA-516 Gr. 60/65/70 carbon steel plate (welded jacket construction) |
| Jacket Welding | SA-516 plate welded to inner body with full penetration welds; PWHT per ASME Section IX for WCB; no PWHT for SS316 |
| Steam Inlet / Outlet | 1/2" to 2" flanged or threaded NPT connections on jacket, positioned for thermosyphon or forced circulation |
| Inner Valve Trim | SS316 / WCB with Stellite 6 overlay seat (gate/globe) / SS316 ball and seats (ball) / PTFE/RPTFE soft seats (ball, on request for lower temp) |
| Packing | Graphite braided with live-loading (high temp standard) / PTFE (on request for lower temperature) |
| Face-to-Face | ASME B16.10 (inner valve) -- overall face-to-face includes jacket thickness, typically 50--100 mm larger than standard valve |
| Operation | Handwheel (gate/globe, up to 6 inch) / Gear operator (8 inch and above) / Lever (ball, up to 4 inch) / Actuator |
| Leakage Class | API 598 / EN 12266-1 -- metal seated standard leakage (gate/globe); Class A (soft seat, ball); zero visible leakage for jacket weld joints |
| Temperature Range | Inner valve: up to +425 deg C (WCB) -- up to +540 deg C (WC6); Jacket steam: up to +200 deg C saturated steam (10 bar) |
| Component | Material |

The Jacketed Valve -- Steam Jacketed Molten Sulphur / Bitumen 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.
