Description

The safety valve is an automatic discharging pressure unit for pressured equipment, containers or pipe roads. When the protected pressure rises over the permitted value the valve will automatically start to discharge superfluity medium and prevent the system pressure keeping on rising. When the system pressure reduces to a regulated value, the valve will be able to automatically shut and make sure the system in general operation. How to choose the safety valve correctly will be concerned to the users economic benefit and the safe for operators and equipment.
ThIS types are used for the equipment and pipeline of the petroleum gas, air,water, etc.medium what the working temperature are less than 300℃.
