In industrial fluid systems, pressure control is a central aspect of equipment safety, efficiency and stability. Spirax Sarco, as a global expert in steam solutions, has made its series of self-acting pressure reducing valves the ideal choice for steam, water, compressed air and oil systems with excellent performance and wide applicability. The following is a comprehensive analysis of this "all-rounder" for industrial fluid control from three aspects: product matrix, technical advantages and application scenarios.
Diversified Product Matrix: Accurately Matching Different Working Condition Requirements
Spirax Sarco self-acting pressure reducing valves have built a complete product system with modular design, covering DN15 to DN150 caliber range, materials including ductile iron, stainless steel (316L), etc., and adapting to a variety of pressure ratings from PN16 to PN40, Class150 to Class300, etc., as well as connection standards (BSP, NPT, clamp, etc.). The following are highlights of the core product line:
Product Series | Model Example | Applicable medium | Caliber range | Material Characteristics | Connections and pressure ratings |
25P Series | 25P, 25PT, 25T, etc. | Steam, compressed air | DN15-DN150 | ductile iron | PN16/PN25/PN40, BSP, NPT, Class250/300 |
DP Series | dp27, dp143, dp163 | Steam, compressed air | DN15-DN50 | Ductile Iron / Stainless Steel | PN25/PN40, BSP, NPT, Class150/300 |
DRV Series | DRV7, DRV4, DRVFG | Steam, water, compressed air, oil | DN15-DN100 | ductile iron | PN25/PN40, BSP, NPT, Class150/300 |
DEP Series | DEP4, DEPT | Water, steam, oil systems | DN15-DN100 | ductile iron | PN25/PN40, BSP, NPT, Class150/300 |
BRV2 Series | BRV2S, BRV28 | Steam, compressed air | 1/2"-1" | ductile iron | bsp, npt, pn25 |
SRV Series | srv2, srv461, srv55 | Clean vapors, liquids, inert gases | DN15-DN50 | 316L stainless steel | Clamp, BSP, NPT, PN40, Class150 |
Featured Scene Adaptation::
- - Clean fieldSRV461/SRV463 and SRV55 series are made of 316L stainless steel, designed for clean steam, pharmaceutical grade liquids and gases that do not react chemically to meet the hygiene standards of the food and pharmaceutical industries.
- - fluid system: Optimized for liquid media, the LRV2B/LRV2S series is suitable for ground 1 zone scenarios with 1/2"-1" bore and ensures stable liquid pressure control.
Second, the technical advantages: self-acting design of "intelligent" and "reliable"
Spirax Sarco self-acting pressure reducing valves do not require an external power source, through the medium's own pressure to achieve automatic adjustment, its core advantages are reflected in:
- 1. Self-driven control to simplify system complexity
- - Utilizing the principle of balance between spring force and medium pressure, real-time response to pressure fluctuations, without the need for electric or gas control devices, reducing energy consumption and maintenance costs, especially suitable for remote or no power source scenarios.
- 2. Dual protection of material and structure
- - Ductile cast iron has high strength and corrosion resistance and is suitable for conventional industrial environments; 316L stainless steel models excel in acid, temperature and intergranular corrosion resistance and are suitable for high temperature, high cleanliness or corrosive media.
- - The use of wear-resistant materials in the sealing structure ensures zero leakage in long-term use, for example, the SRV series is optimized for clean scenarios with clamp connections to avoid the risk of leakage in flanged connections.
- 3. Wide range of operating conditions, precise pressure stabilization
- - Covering steam (high temperature and high pressure), oil systems (viscous media), compressed air (gas characteristics) and other different media pressure control needs, the pressure adjustment accuracy can reach ± 5% or less, to meet the stable operation of precision equipment requirements.
III. Application Scenarios: Full coverage from industrial to specialty fields
- 1. Energy and Power Systems
- - In the steam pipeline network, the 25P and DRV series can depressurize the high-pressure steam output from the boiler to the required pressure of the steam-using equipment (e.g., heat exchangers, dryers, etc.), avoiding damage to the equipment due to overpressure, and at the same time, improving the heat energy utilization rate.
- - In compressed air system, DP and BRV2 series are used for post-processing of air compressor, stabilizing the pressure of air source for pneumatic tools and instruments in workshop and reducing equipment failure.
- 2. Chemical and petroleum industry
- - DEP series is suitable for oil system pressure adjustment, such as lubrication oil circuit, hydraulic system, to ensure the stability of equipment lubrication and power transmission; DRV series can cope with corrosive media, to protect the safe operation of chemical pipeline.
- 3. Food and Pharmaceutical Manufacturing
- - SRV461/SRV55 and other clean series products, through the 316L stainless steel and clamp connection, to meet the requirements of CIP (in-line cleaning) and SIP (steam sterilization), commonly used in pharmaceutical workshops clean steam piping, food processing sterilization equipment.
