DOUBLE PILOT OPERATED CHECK VALVE 1/4"
VT008004 1/4” BSP – Double pilot operated check valve (block type)
Product description:
The VT008004 double pilot operated check valve is designed for secure locking of hydraulic cylinders in both directions. The T-configuration block design prevents unwanted movement under load and allows reverse flow only when pilot pressure is applied. Its compact design makes it ideal for hydraulic systems with lower flow rates.
Main features:
- Type: Double pilot operated check valve, block type
- Part number: VT008004
- Connection (R1): 1/4” BSP
- Max. flow rate: 12 l/min
- Maximum operating pressure: 350 bar
- Pilot ratio: 1 : 4
- Cracking pressure: 2 bar
- Housing material: Steel
Operating Principle
This is a double pilot operated check valve, meaning it allows flow only when a control (pilot) pressure is applied to the opposite side. By default, internal springs keep the valve closed to prevent backflow. When pressure is applied to one pilot port (e.g., C1), it opens the opposite flow path (e.g., V1), allowing hydraulic fluid to pass.
With a pilot ratio of 1:4, even a relatively low pilot pressure is sufficient to open the valve. It is commonly used in applications that require a hydraulic actuator to remain stationary until intentionally released.
