In industrial fluid control, valve performance is directly related to system safety, efficiency and sustainability. As a global specialist in steam solutions, theSpirax SarcoWith its innovative design and excellent quality, it occupies an important position in this field. Its bellows-sealed globe valves, with unique technical advantages and a wide range of application scenarios, have become the preferred products in many industrial fields.

I. Brand Strength: Global Leader in Steam Solutions

Spirax Sarco is a century-old British company specializing in steam system solutions, with operations in many countries and regions around the world. With "Total Steam Solutions Experts" as its core positioning, the company is committed to providing customers with efficient, energy-saving and safe fluid control products and technical support. Its products are widely used in the food and beverage, pharmaceutical, chemical, power and other industries, with excellent reliability and innovation, has become a trusted brand in the global industrial field.

Second, product characteristics: innovative design to achieve excellent performance

Spirax Sarco bellows sealed globe valves are characterized by"Zero leakage, long life, maintenance free"As a core strength, it is fully optimized for the demanding needs of industrial environments:

1. Revolutionary seal design
   adoptionDouble or triple stainless steel bellows sealing structureThe valve is designed to eliminate the risk of stem leakage and meet strict international environmental and safety standards. Even in the event of accidental bellows failure, the packing seal on the stem provides secondary protection to ensure system safety. This design not only meets the sealing needs of steam, chemical and other high-risk scenarios, but also saves energy by reducing leakage, helping companies reduce operating costs.

2. Durability and Reliability

   • Material SelectionThe valve body is available in cast steel, stainless steel and other materials according to different working conditions, of which the stainless steel model (e.g. BSA6T) is suitable for corrosive environments; the bellows is made of corrosion-resistant titanium-reinforced stainless steel, with a fatigue life in accordance with international standards, and can withstand frequent switching operations.
   • Structural optimization: Non-lift handwheel, lock nut and other designs enhance the vibration resistance of the valve, so that it can be stable in the temperature range of -29 ° C to 425 ° C and the pressure range of 0-102 bar g, adapt to complex industrial environments.

3. Ease of operation and maintenance

   • Ergonomic handwheel: Ergonomic design, labor-saving operation, and with on/off position display for real-time monitoring.
   • Maintenance-free features: The bellows seal structure requires no periodic lubrication or adjustment, significantly reducing maintenance costs; internal components can be quickly disassembled if they need to be replaced, and all gaskets are asbestos-free and environmentally friendly.

Third, diversified applications: covering the whole industry fluid control scene

Spirax Sarco bellows-sealed globe valves offerFull caliber range from DN15 to DN400It supports a variety of connection methods such as flange, welding, etc. It can be adapted to a variety of industrial fluids such as steam, air, heat media, oil, etc. The main application scenarios include:

• switching control: Steam and condensate systems, compressed air piping, hot/chilled water systems, etc. to ensure reliable on-off of fluids.
• throttle: By means of optional throttle spool or balancing spool, it can replace the bypass valve to realize rough adjustment of pressure and flow rate, which is suitable for balancing pipeline, rough control system and other scenarios.

Different models are optimized for niche requirements, for example:

• BSA2T Series: Suitable for low pressure scenarios up to PN16/PN25, maximum operating temperature 230°C with R-PTFE soft seats, up to 350°C with metal seats.
• BSA3T Series: Covering medium and high pressure scenarios such as PN25/PN40 and ANSI Class 150/300 to meet the needs of high temperature and high pressure steam systems.
• BSA6T SeriesThe product is made of all stainless steel and is designed for corrosive environments with a maximum allowable pressure of 40 bar g and a temperature of 400°C. The product is available in a wide range of sizes and sizes.

Fourth, technical parameters and selection guide

Selection Points::

• Select the valve body material (cast steel/stainless steel) according to the nature of the fluid;
• Match the model to the system pressure and temperature (e.g. PN100 corresponds to Class 600);
• Throttle spools or balancing spools are available as options when a throttling function is required.

V. Service and support: global network to protect customer value

Spirax Sarco not only provides high-quality products, but also creates added value for its customers through its global technical support network:

• Customized SolutionsCustomized services for special conditions (e.g. ultra-high pressures, extreme temperatures) and evaluation of molding possibilities even for small orders (with attention to cost-effectiveness).
