This article introduces the Spirax Sarco 25P series of pilot-type pressure reducing valves in detail, including its ability to achieve precise pressure control, a variety of combinations of functions and other outstanding features and advantages of use, explains the economic and safety significance of pressure reduction in the steam system, and describes its working principle of stabilizing the downstream pressure through the synergistic action of pilot valves and main valves. It also explains the selection method and typical application scenarios of this series of pressure reducing valves, as well as the characteristics of other regulating valves in the 25 series (such as 25PE, 25BP, 25T, 25PT, etc.), and introduces the component composition, solutions and advantages of the pressure reducing station, comprehensively presenting its important value in steam systems.

This article introduces Spirax Sarco Engineering (China) Co., Ltd.'s general industrial control valves, including the Spira-trol™ and HITER series, describing in detail their types, body materials, sizes, connections, flow rates, etc. It also explains the role of the valves in improving product quality, process efficiency, and lowering the cost of using the valves, as well as solutions for problems such as resistance to fluids, noise, cavitation, etc. It also mentions the pneumatic and electric actuation methods and the characteristics of the related positioner, and also mentions the features of pneumatic and electric actuation methods and the related positioner. The solution to the problem, while mentioning the pneumatic and electric drive and the characteristics of the relevant positioners

This article focuses on Spirax Sarco self-acting pressure reducing valves and systematically introduces its product system and application value. The series covers 25P, DP, DRV, DEP, BRV2, SRV and other models, suitable for steam, water, compressed air, oil and other media, with an aperture range of DN15-DN150, made of ductile iron and 316L stainless steel, and supporting a variety of connection forms, such as BSP, NPT, clamp, and pressure classes from PN16 to Class300. The products do not require external power source, through the self-acting design to achieve automatic pressure adjustment, both high-precision pressure stabilization (within ± 5%), corrosion resistance, zero leakage and other technical advantages, widely used in energy, chemical, food and pharmaceutical industries, fluid control scenarios.

This article focuses on Spirax Sarco's float steam traps, which have become the benchmark for efficient drainage of industrial steam systems after 80 years of technology iteration. Core technologies include self-calibrating main valves, water hammer combinations, corrosion-resistant evacuation valves, and optional steam lock rupture (SLR) devices, which provide the advantages of rapid discharge, rugged construction, corrosion resistance, and large discharge capacity.

The products cover FTGS14, FT14, FT43 and other series, suitable for different pressure levels from PN16 to PN100, made of ductile iron, stainless steel, carbon steel, etc., supporting threaded, flanged, socket welded, etc., with a maximum differential pressure of up to 80 bar and a temperature range from -29°C to 425°C. The products are available in a range of sizes from 1.5 to 2.5 mm, with a maximum differential pressure of up to 80 bar. The working principle is based on the floating ball with the condensate level changes to control the main valve switch, with the air venting valve to achieve efficient separation.

This article focuses on the core product of Spirax Sarco, the global steam solutions specialist -- Bellows Sealed Globe Valves, and comprehensively analyzes its technical advantages and industrial application value. This series of valves adopts double/triple-layer stainless steel bellows seal design to realize "zero leakage", with cast steel, stainless steel and ergonomic handwheels, combining durability and ease of operation, and can be stably operated from -29°C to 425°C and 0-102 bar g. The products cover the full range of DN15-DN400, supporting flanges of up to 1.5 mm and up to 1.5 mm. The products cover the full range of diameters from DN15 to DN400, support flange/welded connections, and are suitable for steam, chemical fluids and other scenarios. BSA2T/3T/6T models are available to meet the needs of different pressure levels. Relying on the global technical network, Spirax Sarco provides customers with customized solutions and full life-cycle services to help industrial fluid control achieve high efficiency, energy saving and safety.
