Kick Down – Hydraulic Pressure Lock Valve

The Kick-Down valve can save machinery if something becomes blocked, stuck, or jammed.

Hydraulic valve similar to a fuse – safety valve

If the pressure rises above the set value, the valve trips like a fuse and relieves the pressure. The valve then acts as a safety valve at abnormally high pressure to prevent machine failure. Examples include mills, screw conveyors, hydraulic presses, or conveyor belts where a foreign object has become stuck.

Detect unwanted pressure spikes

The Kick-Down safety valve also makes it easier to detect unwanted pressure spikes. This can indicate a system fault that should be addressed. A regular pressure relief valve closes when the pressure drops below the set value, so unwanted high pressures can go unnoticed.

A regular pressure relief valve returns to its closed position so the system can continue running, but Sun’s Kick-Down valve requires a reset before it closes again. However, it cannot replace a standard system pressure relief valve or shock valve, which should always be used.

Kick-Down hydraulic valve at a glance

• Functions like a fuse
• Ports 1 to 2 remain open until reset
• Stays open as long as pressure at port 1 exceeds pressure at port 2. To reset, the flow from port 1 to port 2 must decrease and the pressure at port 2 must be equal to or greater than the pressure at port 1
• 350 Bar on all ports, 30 – 480 L/min
