The SLD200X Pressure Reducing Valve is engineered to maintain a stable downstream pressure regardless of variations in the inlet pressure. It features a pilot-operated mechanism for precise control and reliable performance, making it ideal for industrial and municipal applications. Its robust design ensures durability and efficient operation in demanding environments.
Maintains stable downstream pressure for system reliability
Pilot-operated design ensures precise pressure regulation
Durable construction with corrosion-resistant materials
Low-maintenance design reduces operational costs
Suitable for water, air, and non-corrosive fluid systems
A relief pressure valve is made up of the main valve (2), pilot valve (1), needle valve (5), ball valve (3), and the pressure gauge (4). It mainly controls the fixed export pressure of the main valve, which can be changed by adjusting the pilot valve. The valve adapts to changes in inlet pressure but maintains a constant outlet pressure. It is suitable for industrial water supply, firefighting systems, and domestic water pipelines.
