Hydraforce Solenoid Valve Replaced
Precision Check Valve Control with the Hydraforce Solenoid Valve Replaced DF10-05 Hydraulic systems need reliable valves to prevent backflow, separate circuits, and protect pumps from pressure spikes. The Hydraforce solenoid valve replaced by Flying Bull (Model DF10-05) is a direct-acting, 2-way, normally open check valve designed for ordinary pressure hydraulic systems. It is built to meet or exceed Hydraforce specifications for construction machinery and industrial equipment. The DF10-05 solenoid valve is a normally open valve. In its de-energized state, the valve allows oil to flow freely. When the solenoid is energized, the internal poppet moves to close the flow path. The normal cracking pressure (opening pressure) is 1.6 bar. Custom opening pressures are also available, such as 2.6 bar or 4 bar. Key technical parameters: Maximum working pressure: 315 bar. Maximum flow rate: 75 ml/min (control flow). Internal leakage: less than 0.3 ml/min at 210 bar (very tight seal). Filtration requirement: 25μm or better. Standard cavity: T5-1. Standard valve block models: T5-11, T5-13, T5-14, T5-16. Temperature range: -30°C to +100°C (butadiene rubber seals). Media: Oil. Four key applications of a hydraulic check valve like the DF10-05: 1. Check function (prevent reverse flow) – In hydraulic systems, the check valve stops oil from flowing backward. In pneumatic systems, it prevents compressed air backflow. This is the basic function of any check valve – allowing flow in one direction only. 2. Reverse flow control (with throttle) – The check valve can be combined with a throttle valve to create different flow speeds. For example, fluid flows slowly in the forward direction (through the throttle) but quickly in the reverse direction (free flow through the check valve). This is common in systems that need fast retract and slow extend. 3. Prevent system overpressure – Install the check valve at the pump outlet. If system pressure suddenly spikes, the valve prevents reverse flow that could damage the pump. When the pump is not running, the check valve also stops oil from draining back to the tank – keeping the system primed. 4. Separate oil circuits – Check valves can isolate different hydraulic circuits. This prevents pressure fluctuations or flow demands in one circuit from interfering with another circuit. It is essential for machines with multiple simultaneous functions. Flying Bull’s Hydraforce solenoid valve replaced DF10-05 is 100% brand new, manufactured in Zhejiang, China, and backed by a 1‑year warranty. Delivery takes 5–7 working days. Custom opening pressures and coil voltage options are available upon request. For equipment owners and repair shops, the DF10-05 offers a reliable replacement for worn or failed Hydraforce check valves. Choose Flying Bull for quality hydraulic components.

Application of hydraulic check valve
1. Check function: Check valve in the hydraulic system can prevent the oil from flowing in the opposite direction, in the pneumatic system can avoid the backflow phenomenon of compressed air.
2 Check the reverse action: The check valve can be combined with the throttle valve to form an actuator, so that the fluid can flow slowly in the forward direction and quickly in the opposite direction. Or the flow can be slowed down when moving forward, and the free flow loop can be performed when moving backward.
3. Prevent system pressure from being too high: The check valve is installed at the outlet of the pump, which can avoid damage to the oil pump when the pressure in the system suddenly becomes high and play a check role. The check valve also prevents oil from the system from flowing back into the mailbox when the pump is not working.
4. Separate the oil circuit: The check valve can play the role of separating the oil circuit to avoid mutual interference between the oil circuit.
Company Introduction
Frequently Asked Questions (FAQ)
1. What is the model number and normal opening pressure of this valve?
The model number is DF10-05. The normal opening pressure (cracking pressure) is 1.6 bar in the standard version. Custom opening pressures such as 2.6 bar or 4 bar are available for order.
2. What is the maximum operating pressure and flow rate of the DF10-05?
Maximum working pressure is 315 bar. Maximum flow rate (control flow) is 75 ml/min. Internal leakage is very low – less than 0.3 ml/min at 210 bar.
3. How does the DF10-05 solenoid valve work?
This is a normally open valve. When de-energized, the valve allows oil to flow freely. When the solenoid coil is energized, it creates a magnetic force that moves the internal poppet to close the flow path. The valve is used as a check valve with solenoid control.
4. What is the difference between a standard check valve and this solenoid-operated check valve?
A standard check valve opens and closes automatically based on pressure difference (flow direction). The DF10-05 is a solenoid-operated check valve – you control when it opens or closes via an electrical signal. That allows you to hold pressure in a cylinder or circuit even when the pump is off, then release it on command.
5. What are the four main applications of a hydraulic check valve?
(1) Prevent reverse flow – stops oil from going backward. (2) Reverse flow control – when combined with a throttle, creates slow extend / fast retract. (3) Prevent overpressure damage – installed at pump outlet to protect against pressure spikes. (4) Separate oil circuits – prevents interference between multiple hydraulic functions on the same machine.
6. What temperature range and filtration are required for this valve?
The valve uses butadiene rubber seals rated for -30°C to +100°C. The hydraulic oil must be filtered to 25μm or better to prevent internal contamination and sticking.
7. Does the Hydraforce solenoid valve replaced DF10-05 come with a warranty?
Yes. Flying Bull provides a 1‑year warranty against manufacturing defects. Damage caused by contaminated fluid (filtration below 25μm), incorrect installation, overpressure, or voltage issues is not covered. Always use clean hydraulic oil and maintain proper filtration.
8. Is this valve a direct replacement for an original Hydraforce DF10-05?
Yes. This valve is manufactured to replace the original Hydraforce DF10-05. It matches the same T5-1 cavity dimensions, flow characteristics, and pressure ratings. Always verify your original valve number before ordering.
