Stainless Steel Pneumatic Control Valve, 6 IN, 300 LB, CF8
Key Specifications / Features
Hits: 2
Our Pressure Balanced Cage Type Globe Control Valves are designed for heavy-duty services. The compact valve body features an S-shaped flow passage for low pressure loss and a stabilizer to regulate turbulent flow, ensuring large flow capacity, rangeability, and high accuracy. The pressure-balanced valve plug allows high differential pressure control with minimal actuating force. Equipped with a powerful diaphragm actuator with multiple springs, these valves are made of ASTM A351 CF8 and have flanged ends. They are suitable for high or low temperatures (-196 to +450°C) and high-pressure lines, offering dynamic stability, low noise, and resistance to cavitation and flashing.
