When you’re working with hydraulic systems on your tractor or implement, controlling flow direction is critical for safe operation and protecting expensive components. This single flow back valve does exactly what you need—it allows flow in one direction while preventing backflow that could damage pumps or cause unwanted movement of hydraulic cylinders when you shut things down.

What You’re Getting

  • 1-inch pipe thread inlet and outlet ports fit standard hydraulic plumbing
  • Single pole single throw design for reliable on-off control
  • Positively switched operation means no guesswork about valve position
  • Includes a half-meter cable for convenient remote switching
  • Prevents dangerous backflow that can damage hydraulic components

Built for Real Farm Work

This valve is perfect for hydraulic systems on tractors, implements, and other agricultural equipment where you need to control flow direction. Whether you’re operating a loader, three-point hitch system, or hydraulic-driven implement, this back valve ensures hydraulic fluid flows the right way and stops when it should. It’s particularly useful in systems where gravity or load pressure could cause unwanted movement when the system is shut off.

Made to Last

Farm hydraulics operate under high pressure and face constant cycling, temperature changes, and contaminated oil. This valve is built to handle those conditions with robust internal components and quality sealing materials that maintain proper operation even after thousands of cycles. The threaded connections provide a secure, leak-free installation that holds up under field conditions.

Installation Notes

The 1-inch NPT threads make installation straightforward using standard pipe fittings and thread sealant. Mount the valve where the cable can easily reach your control panel or switching location. The positive switching action gives you clear feedback about valve position, so you always know whether flow is enabled or blocked.
