SNRI 拥有 100 多年的法国制造历史，以其 Malbranque 和 SNRI 品牌设计和制造用于石油、天然气和各种工业过程的阀门。

SNRI设计部使用最新的计算机辅助技术，根据客户需求优化和调整截止阀、闸阀和止回阀的设计，精心制作和创造新产品。

一系列安全设备（安全阀、安全阀和用于储罐的 Fire-Clap）使 SNRI 成为确保您的安装符合所需的最佳合作伙伴的首选合作伙伴。

在我们的 Ruffec（法国）工厂进行制造，再加上欧洲铸造厂的支持，可以将卓越的质量和响应能力相结合。

SNRI 的范围包括所有压力，最高可达非常高水平（2500 级），兼容极低温度 (-196°C) 和非常高 (+650°C)，满足以下应用的所有需求：

- 石油、天然气和腐蚀性液体
- 低温
- 蒸汽

石油和天然气应用

Malbranque 品牌，得到最重要的炼油公司和工程中心的认可和认可；为勘探作业、炼油和石化中最恶劣的环境条件设计和制造阀门。这些产品特别适用于气体处理和腐蚀性流体。

提供专门的服务，建议对自 40 年来在全球安装的 Malbranque 产品提供持续的积极支持。我们的“Valco 阀门服务”团队可以进行现场维护、维修和更新，以保证所有产品的初始性能水平，无论其投入使用的日期如何。

SNRI 品牌提供适用于燃料储存的安全型阀门：我们的“Fireclap”阀门可确保防止因储存易燃产品而引发的火灾风险。安全阀由于在关闭时具有出色的密封能力，可最大限度地减少库存产品的损失。

低温应用

凭借 SNRI 和 Malbranque 品牌，Valco 集团在许多低温流体市场上处于领先地位。

因此，50 年来，SNRI 显然是船上甲烷运输船的世界领先者。它的范围涵盖了用于浮动码头和海上 LNG 装置的高压阀。他们的专业知识使 SNRI 成为海军工业的合作伙伴，为使用 LNG 的推进系统开发阀门。

Malbranque 凭借其在低温应用类型冷箱方面的行业专业知识，是气液装置和工业气体处理设计师和工程师的公认合作伙伴，也包括 LNG 接收站。

蒸汽和工业应用

对材料结构及其最佳概念的掌握证实了 SNRI 作为蒸汽应用的主流制造专家，适用于所有类型的行业。

从 1960 年代末期开始，SNRI 就是核工业的积极合作伙伴。整个系列提供一系列与不同质量水平和标准相关的铸造和锻造阀门以及特定产品，例如用于涡轮机保护的自由流动反向电流阀门。

SNRI 的产品也出现在许多传统类型的锅炉或热电联产装置以及许多不同的蒸汽网络中。

除了蒸汽应用，SNRI 还根据严格的行业标准开发产品，例如果汁和果肉的工业过程。

French fabricant for over a 100 years, SNRI designs and makes valves for Oil, Gas and diverses industrial processus under their Malbranque and SNRI brand names.

SNRI's Design dept. elaborates and creates new products using latest computer-aided technologies that optimize and adapt the designing of Globe, Gate and Check valves according to customer needs.

A range of Security equipment ( Safety valve, Relief valve et Fire-Clap for tank storage ) makes SNRI a choice partner to assure your installations top conformity that’s needed.

Fabrication carried-out in our Ruffec (France) plant, along with the support of European foundries, allows combining excellent quality and responsiveness.

SNRI's range includes all pressures up to very high level (class 2500), compatible to very low temperatures (-196°C) and also to very high  (+650°C) that covers all needs for the following applications:

- Oil, Gas and corrosive liquids
- Cryogenic
- Steam

Oil & Gas applications

Malbranque brand, recognized and approved by the most important refining companies and engineering centres ; designs and fabricates valves for the harshest environmental conditions in exploration operations, refining and petrochemical. These products are particularily adapted for gas treatment and corrosive fluids.

Offering a dedicated service, continued active support is proposed for Malbranque products in service since 40 years installed world-wide. On-site maintenance, repair and renewal can be executed by our "Valco Valves Services" teams to guarantee all of the products’ initial performance levels no matter whatever the date of their being put into service.

SNRI brand supplys security type valves well adapted for fuel storage :  our "Fireclap" valve assures positive security against risks of fire menaced by the stocking of flammable products. Relief valves, due to the excellent sealing capacity at moment of closing, minimizes stocked product loss.

Cryogenic applications

With SNRI & Malbranque brand names, Valco Group is a leader on many markets concerning cryogenic fluids.

SNRI is therefore an evident world-leader since 50 years for on-board methane carriers. It’s range covers up to High Pressure valves for floating terminals and Off-shore LNG units. Their expertise has enabled SNRI to be partners to the naval industry for the development of valves for propulsion systems using LNG.

Malbranque, due to their industrial expertise of cryogenic applications type Cold box, is an acknowledged partner of air liquid units and industrial gas treatment designers and engineers, also including for LNG terminals.

Steam & Industry applications

Mastery of material structure and their optimal concept confirms SNRI to stand out as a prevailing fabricant specialist of Steam applications, for all types of industry.

SNRI is an active partner in Nuclear industry since the beginning, at the end of the 1960’s. The whole range offers a line of casted and forged valves relevant to different quality levels and standards as well as specific product such as Free Flow Reverse Current valve for turbine protection.

SNRI's products are also present on many conventional type Boilers or cogenerations, as well as many various steam networks.

Other than steam applications, SNRI also develops products according to severe industry standards such as for the industrial processes of juices and pulp.
