EMERGENCY PRESSURE/VACUUM RELIEF VALVE
Finekay Series 8170 Manhole Cover with pressure and vacuum relief, provides both emergency pressure relief and vacuum relief when installed on the manhole of a storage tank. In emergency situations (external fire involvement of the tank), normal venting devices may be too small to prevent over-pressurization of the tank. The Series 8170 provides the necessary pressure relief capacity to maintain the tank in a safe operating range. The integral vacuum vent provides
Additional protection against tank collapse due to excessive vacuum in the vapor space.

For 20 years, the back-fire relief valve, breather valve, pilot valve, emergency-relief valve, gas control valve and other products of Finekay Company have been providing the protection for the refinery, chemical plants and other facilities which use the fixed atmospheric pressure storage tank. The products of Finekay refer to various systems and industries, which are applied in the whole world. During 20 years, Finekay has been engaged in offering the innovative security solutions, high-quality products and complete services, strengthening the security of your factory. Our products can save costs through reducing the medium consumption and contribute to protect the environment as well as benefit the next generation. The quality and function of Finekay have been another name of products.
With the increasingly strict requirement on the security and increasing enhancement of environmental awareness, enterprises and governments of each country formulate lots of laws and regulations in recent years. It is required that industries including chemistry, medicine and petrochemical industry which specialize in processing, storing and delivering the flammable gas, liquid, steam and volatile solvent should pay more attention to the security production and environmental issue. The new-generation security products developed by Finekay such as back-fire relief valve and breather valve are made under such background.
In the development, design and test of the back-fire relief valve, Finekay thoroughly presents the latest international standard of the back-fire relief valve test ISO16852 and the application standard of the back-fire relief valve NFPA67. The breather valve of Finekay applies the advanced 10% overpressure valve technology, with the excellent performance and small leaking amount.
Although the requirement on the security device standard internationally becomes stricter, we should still be careful while we choose the type of the back-fire relief valve. We should try to act according to the actual circumstances to choose and install proper back-fire relief valve. For the selection of the breather valve, we also should follow the same principle. Below are the general principle of Finekay security devices and the basic theoretical knowledge of the back-fire relief valve and breather valve. If you need more specific information and technical data, we can dispatch the professional staff or provide more detailed Finekay product catalog.
Besides the production standard of security devices, we can provide you with the back-fire relief valve, breather valve and other facilities for the storage tanks of special standards. What's more, we can make the design and production according to the actual process requirements of users. These products not only can meet the actual work demands, but also conform to the international standard about the safe products and test.
The technical experts of Finekay are equipped with rich work experience. They can do different kinds of maintenances on products. We are able to provide customers with the specific information of various products, such as the operation manual, technical drawing, specification and installation & maintenance guide. Additionally, our after-sales service group can sign the installation and maintenance contract with customers.
