Diaphragm-Type Steam Pressure Reducing Valve with High Wear Resistance & Stabilization

Product Description

Overview

The diaphragm-type steam pressure reducing valve is a high-performance pressure regulation device specifically designed for high-temperature and high-pressure steam systems. With exceptional durability and precise control as its core advantages, it is widely used in industries such as petrochemicals, energy, food processing, and pharmaceuticals. The valve body is constructed from high-quality carbon steel (WCB) or stainless steel (CF8/CF8M), balancing cost-efficiency and corrosion resistance. It can adapt to complex operating conditions ranging from -20°C to 550°C, meeting the demands of both general industrial and high-purity steam applications.

The key components-the main disc and seat-undergo heat treatment and cryogenic processing, achieving a hardness of up to 60 HRC, comparable to high-speed steel. This significantly enhances wear resistance and cavitation erosion resistance, effectively withstanding steam erosion and cavitation damage. The valve is equipped with a 200-mesh (75μm) precision filter to effectively intercept pipeline impurities, preventing pilot valve clogging-especially suitable for aging steam pipeline systems. Paired with a high-sensitivity diaphragm, it detects pressure fluctuations in real time, ensuring stable downstream pressure with an accuracy of ±5%~10%, eliminating overpressure risks.

Featuring a modular design for quick maintenance and replacement, this valve significantly reduces downtime. With its extended service life and reliable performance, it enhances production efficiency, lowers operational costs, and provides comprehensive safety protection for critical equipment such as boilers, heat exchangers, and drying systems.
