Product Description

How to choose the safety valve
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 valves 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. The following are the ways to be introduced for how to choose the safety valve.

AY42H, TA802Y type safety overflow valves are to be applied to pipelines in high-pressure pump stations to provide over pressure protection
