Dongfang Yoyik is professional manufacturer of Pressure Relief Valve 3.5A25. We make high quality valves for power plant users. It is specially designed for steam turbine generator hydrogen cooling system.
High strength with fine brass material.
Perfect sealing with zero leakage.
High security to protect the hydrogen system.
Pressure Relief Valve 3.5A25, also called as Safety Valve, is an economical and compact high-pressure safety valve with excellent set pressure control. It is driven by the static pressure of the medium in front of the valve. When the pressure exceeds the opening force, it opens proportionally. The valve can be sealed within a small range of the set pressure, and its sealing can be ensured even after repeated venting. It is used in the hydrogen equipment to ensure that the hydrogen pipeline system will not have accidents due to excessive pressure.
It is reliable choice for hydrogen pipeline of steam turbine generators in power plant. It can also be used on any gas pipelines for pressure control.
