Lincoln® Thermal Pressure Relief Kit for Diaphragm Pumps

Managers of vehicle service centers can now turn to our new thermal pressure relief device to protect against possible damage to their closed pipe systems caused by thermal expansion. For example, as oil warms, it expands and causes pressure - sometimes oil that was 300 psi becomes 2,000 to 3,000 psi.

Such pressure spikes can cause costly damage if they exceed the design capacity of pipes and system components. Our pressure relief valve returns fluid/material back to the tank, limiting the pressure to protect the system.

• Range: 5 to 75 cycles/min. 
• Power: 9 V lithium-ion battery 
• External Signal: 2 A 30 V DC
• Relay: 0.5 A 125 VAC
