UNWAVERING commitment to INNOVATION and QUALITY
Sud Robinetterie Industrie (SRi), founded in Marseille in 1978, is a respected French valve manufacturer specializing in high-integrity isolation solutions for the oil & gas, petrochemical, power, mining, and chemical industries. With over 80% of its production exported across five continents, SRi delivers reliable valve technologies from exploration to refining, and increasingly supports nuclear applications through its expanded 12,000 m² facility (1,000 m² of which is dedicated to nuclear-grade manufacturing)
The company’s strong quality credentials include ISO 9001, ISO 14001, ISO 45001, API 6A, API 6D, and RCC-M Q2 certification—underscoring their rigorous compliance with international and nuclear industry standards.
SRi’s versatile product range spans floating and trunnion-mounted ball valves, side- and top-entry designs, cryogenic, multiway and wafer configurations.

SRi’s versatile product range spans floating and trunnion-mounted ball valves, side- and top-entry designs, cryogenic, multiway and wafer configurations.
SRi Trunnion Ball Valves
- Side-Entry Trunnion TypeThe 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 Trunnion TypeThe 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, trim, 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. - Pig Launcher Trunnion TypeSRi 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. - Cryogenic Trunnion TypeWhen 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).
SRi Floating Ball Valves
- Side-Entry Floating TypeTwo parts body cast or forged steels.
Soft or metal seats.
Design & Machining by SRi.
All valves tested after assembly.
All part can be identified and replaced by valve serial number. - Cryogenic Floating TypeWhen 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 Floating TypeSRi 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. - Wafer Floating TypeWafer floating ball valve saves space and weight, thanks to the absence of flange.
