Features

Conrader pressure relief valves have a soft seat valve that provides a tight seal for enhanced safety and reliability. They feature a brass body for durability and resistance to corrosion in demanding environments. These pneumatic safety valves can withstand a maximum temperature of 400 degrees F. They have springs made of stainless steel for structural rigidity and long service life. These pneumatic safety valves offer silicone seals for reliable sealing performance and chemical resistance.
The brand's hard seat safety valves offer precise control between 25 and 350 psi flow pressure. These valves can handle up to 1147 scfm of liquid flow.

Working Mechanism

Pneumatic safety valves operate on the principle of pressure differentials.
When the pressure inside a pneumatic system exceeds a predetermined threshold, the valve's mechanism is triggered.
This triggers the valve to open, releasing excess pressure and preventing overpressurisation.
Once the pressure returns to a safe level, the valve closes automatically, allowing normal system operation to resume.
