Product Introduction
Product Features
- Rated working pressure 31. 5MPa, nominal flow capacity 100L/min, compatible with ISO VG 46 anti-wear hydraulic oil, working temperature range -20℃~+100℃
- Cast steel valve body with hardened stainless steel spool, pilot-operated design for high pressure control accuracy (±0. 3MPa), low pressure loss
- Adjustable pressure range (5~31. 5MPa), with built-in check valve for backflow protection, adapting to system pressure fluctuations
- IP65 protection grade, plate-type installation for easy maintenance and replacement, resistant to humidity, dust and industrial vibration
Applications
- Overpressure protection and pressure stabilization of turbine governing system hydraulic circuits in Bangka Belitung 3 Power plant
- Pressure control of boiler feedwater pump hydraulic loops, coordinating with coal supply data to optimize unit load adjustment
- Auxiliary hydraulic system protection for coal mills and flue gas damper actuators, ensuring coordinated operation with core power generation systems
