Sud Robinetterie Industrie
SRi founded in Marseille, France, in 1978 has a decades long history of serving the oil and gas, power, refining, chemical and, metals and mining industries. SRi started in France by supplying and servicing local refineries.
In 1990 SRi decided to expand into the Machining of trunnion and floating ball isolation valves to its own proprietary custom design. These designs are based on its experience in servicing the oil and gas, and refining industries.
SRi broadened its product line of isolation valves by purchasing VANNES RIGAU in 2005.
SRi now has a full line of isolation valves: gate, globe, check and ball.
Over 80% of SRi’s sales are now exported to markets outside of France primarily to companies in Europe, Africa and Asia.
SRi is a qualified supplier for worldwide and national companies including end-users and EPC contractors.
The high demand for SRi’s quality valves both custom designed and standard has caused
SRi to increase its capacity by building a new facility in its headquarters city of Marseille, France.
SRi Trunnion API 6D/6A Products
Side-Entry
Side-Entry
The side-entry ball valve is the most common and popular design.
Given its great modularity, SRi can manufacture any side-entry ball valves with special options.
In case of maintenance operation, all parts of the valve can be replaced, so valve lifetime is extended.

Top-Entry
Top-Entry
The cover of top-entry ball valve can be disassembled from the body of the valve, so all parts can be easily maintained or replaced in-line.
On demand, trem, trunnion and ball can be made as a monobloc piece. This option increases the reliability of the valve.
This construction allows more flexibility in customization of driving train design,
allowing for example the mounting of an actuator directly on the bonnet without an intermediary bracket.

Engineering & Technologies
SRi uses the latest techniques like CAD, DAO and structural calculations in the conception, verification,
analysis and testing of our products.
A permanent research and development program leading to patents means always more reliability and performance in our products.
SRi is equipped with a finite element analysis software ANSYS.
This software can simulate: Thermal, solid mechanics, mechanics of fluid, fluid/structure interaction.
Other Trunnion Products
Wafer
Wafer
- Wafer ball valve saves space and weight, thanks to the absence of flange.
- This design also allows replacement of a gate valve without modification of the piping should a reduced bore be considered
Cryogenic
Cryogenic
When the expected service or design temperature is out of the standard temperature range of SRi ball valve,
SRi manufactures high temperature or cryogenic ball valves
The minimum temperature of cryogenic ball valve is -196°C.
The maximum temperature of high temperature ball valve is +450°C for TCC (Tungsten Carbide Coating) and +650°C for CCC (Chromium Carbine Coating).

Multiways
Multiways
SRi multiways ball valve can be made, on demand, with L-port, T-port or X-port. Ball valve can be designed as transflow or non-transflow.
The non-transflow avoids connection of 3 or 4 branches during stroke.
The SRi multiways ball valve keeps the valve tight even if the automatic cavity relief by seat leakage is actived.
Pig Launcher
Pig Launcher
SRi pig launcher (or receiver) is safe and much more compact than a pig trap.
Manual or automatic secured access door.
The pig launcher can be equipped with an optional by-pass to allow flow between both sides of the valve if the pig is presented in the valve ball.

DBB
DBB
Double Block and Bleed (DBB) ball valve is made of two balls in one valve body.
A bleeder is added between the two balls of the valve.
This system is equivalent to a Double Isolation Bleed (DIB) single ball valve.
Tandem Ball Valve
Tandem Ball Valve
SRi tandem ball valve is constituted by two balls, like the Double Block and Bleed ball valve,
but the face-to-face dimension is in accordance with ASME B16.10.
On site, a SRi tandem ball valve can replace a single ball valve without modification of the pipe meaning two ball valves instead of only one.

Three parts
This is a three parts, cast and bolted valve. The basic construction has been improved in order to minimize the quantity and variety of parts.
The operating devices (ISO base plate, stem, packing gland and stopping plate) are the same as that of side entry floating valves,
which reduces the quantity of spare parts in stock and allows accessories to be interchangeable.
