What are the differences between a DCV with a spring center or detent option?
Spring centered option This operation means that while ever the valve handle is released the DCV will always spring back to the center neutral control position. Advantages here are that the cylinder operation will always fail safe. Let go of the leaver and the DCV will always finds its neutral position. This option does however mean an operator needs to be continually present. Detent option A valve fitted with a detent option on the other hand will always be mechanically held, by a simple mechanism, in whatever position the leaver was last left in. The cylinder will continue to extend or retract depending on what position the lever remains in. This allows the operator to walk away and the cylinder will continue to either extend or retract without their presence. Downside of course is there are no failsafe measures.
