Industrial Ball Valve
Floating · Trunnion DBB · 3-Piece · DN15–DN600 · PN16/PN40
Reguvale's industrial ball valves provide reliable on/off isolation with low torque and bubble-tight shutoff for oil & gas, chemical, water, mining and power applications. The range includes floating ball valves, trunnion-mounted double-block-and-bleed (DBB) valves and 3-piece / top-entry designs for easy maintenance.
Body materials include WCB carbon steel, stainless steel SS304 / SS316 / SS316L and CF8M, with PTFE, RPTFE, PEEK or metal seats. All carbon and stainless steel ball valves are built with fire-safe design (metal backup seat), anti-static and blow-out-proof stem construction, and are supplied with shell and seat tests plus material certificates.
End connections cover flanged (RF), threaded (NPT / BSP), socket-weld, butt-weld and tri-clamp to match your piping specification.
Key Features
Bubble-tight Shutoff
PTFE / RPTFE seats give zero-leakage isolation, with metal seats available for high-temperature and slurry service.
Fire-safe & Anti-static
Fire-safe design with a metal backup seat (no API 607 certificate held), anti-static device and blow-out-proof stem as standard on carbon / stainless designs.
Floating & Trunnion DBB
Choose floating for general isolation or trunnion double-block-and-bleed for pipeline and instrument isolation.
Flexible Ends
Flanged, threaded, socket-weld, butt-weld and tri-clamp ends to drop into any piping standard.
3-Piece & Top-entry
3-piece and top-entry bodies allow seat and seal replacement without removing the valve from the line.
Tested & Certified
Shell and seat hydrostatic tests, mill certificates (EN 10204) and third-party inspection available.

Ball Valve: Body Construction, Bore and Seat
Ball valves are the default isolation valve for a reason: quarter-turn, tight shutoff, and they stay reliable when they are left alone. The three choices below decide how serviceable they are.
| Construction | Where it is the right answer |
|---|---|
| One-piece | Cheapest and most compact. The ball is inserted through the end, so the valve cannot be re-seated in line — chosen for utility lines where the valve is replaced rather than repaired. |
| Two-piece | The common industrial compromise: the body unscrews or unbolts so the ball and seats can be inspected and replaced. Good availability from DN15 to DN200. |
| Three-piece | The body splits around the ball, so the centre section can be removed for cleaning or re-seating without disturbing the pipe. Used on hygienic, chemical and instrument lines, and where welding is involved. |
| Bore and seat | Chosen when |
|---|---|
| Full bore | The bore matches the pipe, so a pig or a swab passes through and the pressure drop is negligible. Standard for pipeline and piggable duties. |
| Reduced bore | Smaller and cheaper for the same size and pressure rating. Fine where a modest pressure drop is acceptable. |
| Floating ball | The line pressure pushes the ball onto the downstream seat. Simple and effective up to roughly DN150 at moderate pressure. |
| Trunnion mounted | The ball is anchored on bearings so the seat only has to seal, not carry the ball. Used at large sizes and high pressure, and where the actuator torque must stay low. |
| PTFE / RPTFE seat | Chemical resistance and low torque at moderate temperature. The usual choice for water, solvents and dilute acids. |
| Metal seat | High temperature, steam and abrasive media, and where a soft seat would be extruded. Expect a small leakage rate rather than bubble-tight. |
On fire-safe construction, be precise about what you are buying. Our ball valves are built with a fire-safe design principle — a soft seat plus a metal backup seat that holds line pressure after a fire — but we do not hold an API 607 or ISO 10497 certificate. If your specification names one of those, tell us and we will confirm in writing what can be documented before you commit.
Ball valves isolate; they are poor at throttling because the seat sees the full pressure drop the moment the ball cracks open. If you need regulation, say so — the right answer is a control valve or, for coarse duties, a butterfly valve.
Frequently Asked Questions
