Pressure Reducing Valve

NSV Pressure Reducing Valve

Designed for precise pressure regulation in water systems. Features a pilot-operated control mechanism with high sensitivity and accuracy, ensuring stable downstream pressure under varying flow conditions.

The valve incorporates a diaphragm actuator and spring-loaded pilot system, enabling easy adjustment and reliable operation. It is suitable for applications requiring consistent pressure control across wide flow ranges.

Key Features

• Pilot-operated pressure reduction with accurate response
• Easy adjustment via handwheel or external regulator
• Excellent sealing performance with NBR diaphragm
• Full-port design, flanged ends (RF/FF), sizes DN50–DN500
• Operating temperature: 0°C to 100°C, water service
• Body material options: Ductile Iron; Stainless Steel; Duplex Stainless Steel
• Pilot assembly: Zinc Alloy or Stainless Steel; pressure ranges: 0.1–5, 5–9, 7–17 kgf/cm²

Performance Advantages
Pilot-controlled design ensures sensitive and accurate pressure regulation; modular construction allows simple maintenance; NBR diaphragm provides long-term seal integrity; corrosion-resistant materials enhance service life; suitable for parallel or series installation to manage variable flow and high-pressure drop scenarios.

Typical Applications
Water supply networks, fire protection systems, irrigation, industrial process lines, and pressure reducing stations using multiple valves in parallel or series to handle peak loads and low-flow conditions.

Quality Assurance
Hydrostatically tested per ASME B16.34. Supplied with EN 10204 3.1 material test certificate (MTC 3.1) and EN 10204 2.1 certificate of conformity (COC 2.1).
