OPC solenoid valve JZ-PK-002 Harduaganj power
Date:2025/3/13 8:24:28 Visits: Author:Dongfang YOYIK Engineering Co; Ltd,OPC solenoid valve JZ-PK-002 is a high-performance overspeed protection control solenoid valve, which is widely used in the fire-resistant fuel system of steam turbines in power plants. Its main function is to control the hydraulic actuator in the fire-resistant fuel system by controlling the on and off of the oil circuit, ensuring the safe shutdown of the steam turbine in the case of overspeed.
Performance characteristics
1. Overspeed protection function: When the turbine speed exceeds the safe range, the solenoid valve will quickly cut off the hydraulic oil circuit, stop the turbine from running, and ensure the safety of equipment and personnel.
2. Composition of primary valve and secondary valve: The primary valve is responsible for monitoring the speed of the equipment and transmitting the signal to the secondary valve. The secondary valve decides whether to open or close the oil circuit according to the signal of the primary valve, thereby realizing precise control of the oil circuit.
3. Optional voltage: Two voltage options of 110VDC and 220VDC are provided to meet the needs of different users and power supply conditions.
4. High reliability and stability: The use of high-quality materials and advanced manufacturing processes ensures that the solenoid valve can still work stably and reliably in harsh working environments.
Technical parameters
-Model: JZ-PK-002
-Working pressure: Usually suitable for high-pressure fire-resistant oil systems, the specific pressure value needs to be determined according to the actual application scenario.
-Working temperature range: Generally between -20¡æ and +80¡æ, ensuring normal operation under various climatic conditions.
-Applicable medium: fire-resistant oil (such as phosphate fire-resistant oil)
-Connection method: threaded or flange connection, the specific connection size needs to be determined according to the design and space requirements of the equipment.
-Power supply voltage: 110VDC or 220VD
