Pressure Relief Valve

Function and Description

Highly Developed Pressure Relief Valve

Full Lift Technology

The device will start to open as soon as the set pressure is reached and only requires 10% overpressure to reach full lift. Continuous investments in and a commitment to research and development have allowed PROTEGO® to develop a low pressure valve which has the same opening characteristic as a high pressure safety relief valve. This “full lift type” technology allows the valve to be set at just 10% below the maximum allowable working pressure of the tank and still safely vent the required mass flow.

Advanced Manufacturing Technology

Due to the highly developed manufacturing technology, the tank pressure Tank pressure Tank pressure is the pressure within a tank. is maintained up to the set pressure with a tightness that is far superior to the conventional standard. This feature is achieved by valve seats made of high-grade steel with an inserted O-ring O-ring O-rings are ring-shaped gaskets with a round, o-shaped cross section seal Seal A seal prevents or limits unwanted transfer of product from one container to another. Seal is used as superordinate term for all types of sealing elements. , a precisely lapped valve pallet, and a sturdy housing design. After the excess pressure is released, the valve re-seats and provides a tight seal again.
