Sud Robinetterie Industrie (SRi) products

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.

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.

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

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).

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.

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.

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.

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.

Two 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.

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.
