Pneumatic Balanced Globe Control Valve, JIS SCPH2, DN80, 20K

Key Specifications / Features

The Balanced Globe Control Valve is engineered for demanding applications. Its compact design includes an S-shaped flow passage that minimizes pressure loss and a stabilizer to control turbulent flow, delivering high flow capacity, extensive rangeability, and precise flow characteristics. The pressure-balanced valve plug ensures efficient flow control even under high differential pressures with minimal actuating force. Available in DN80, 20K, SCPH2, and ANSI Class 125 LB, 150 LB, 300 LB, and 600 LB ratings, this valve features a powerful diaphragm actuator with multiple springs for reliability. It is ideal for high/low temperature and high-pressure lines, providing dynamic stability, low noise, and resistance to cavitation and flashing.
