Product Description
Purpose
This valve is used for the high building fire fighting system.When the pressure in the water supply pipeline is over the one set for pressure relieving,the pressure reliving valve is opened to prevent both pipeline and equipment from getting damage due to an excessive pressure;and,when the said pressure lowers to the set value,this valve will be closed automatically.
Features
The body uses full-channel streamline design,leaving a small fluid resistance and a great flow.This valve can be used as a pressure reliving valve and also a pressure holding valve.When used as the former,it can relieve the pressure in the water pipe over the safety value set for the pilot valve and keep the pressure in the pipe below the safety value to prevent the system from getting danger due to an excessive water pressure;and,as the latter,it can keep the master valve upstream water supply pressure over a certain set value to make the water supply to the downstream only available when the upstream pressure is higher than the set value so as to ensure the master valve upstream water supply pressure.
Principle
The inlet side of the master valve is connected to the pilot valve via a control pipe and,when the pressure at the side is over the one set for the pilot valve,the pilot valve is opened to relieve the pressure in the upper cavity of the diaphragm and main disc is opened along with.The master valve relieves pressure and,when the pressure lowers to the set one,the pilot valve is closed,so is the master valve.

Company Profile
Founded in 1980 and headquartered in Bei-Zha-Kou Electronic Industrial Park, Jinnan District, Tianjin, a place incorporated into the prosperous Bohai economic rim, Bohai Valve has been and will continue exploring and innovating. In 2014, Bohai Valve was promoted to a non-area-limited group company in China. The group company is committed to providing stable and reliable fluid control solutions aiming at engineering fields including hydropower, thermal power, steel making, metallurgy, petroleum, chemicals, sewage treatment and water systems.
The group company covers a land of more than 80, 000m2 for its valve manufacturing base and casting factory, and possesses all necessary production and testing means. It is a lare valve manufacturer engaged in valve development, manufacturing, and sales.
Major product lines are manufactured with reference to ANSI, API, DIN, BS, JPI, and JIS standards and China's GB standards by means of the latest technologies favored across the world. They include butterfly valves, gate valves, ball valves, globe valves, check valves, hydraulic control valves, cryogenic valves, throttle valves, metallurgical valves, oxygen tubing valves, and HPHT valves, which are available in more than 100 series and thousands of sizes, with pressure rating ranging from 1.0MPa to 10MPa and port size from DN50 to DN4000. These valves can be operated manually, electrically, pneumatically, hydraulically, and/or electro-hydraulically, and made of different materials, manufactured to different types and sizes, and therefore meet the need for one-stop purchasing.
To ensure the stability and reliability of its quality, the group company uses CNC machine tools, CNC multi-station machining center, extra large processing size (5 meters) vertical lathes and large drilling center for its major machining tasks, maintaining a world automation level throughout its production process. The group company also procures advanced detection equipment and type testing platform for nondestructive testing, spectrum analysis, CMM measuring, supersonic spraying, heat treatment, low leakage test, life test, low temperature performance test, and wear and high temperature resistance test, which not only enhances the machining and testing ability of the factory but also supports the development of new products for harsh industrial environment, thus ensuring the stability of product quality.
The company also has a large casting base and owns a B3R 125 electric furnace, 3-ton, 5-ton, and 10-ton cupola furnaces, a mobile resin molding line, an epoxy powder spraying line, and a testing center, providing strong and powerful hardware guarantee for the manufacturing of quality valves.
Bohai Valve has long used the advanced management concepts to their factory management and applied the resource management system and warehouse management system to all its products for quality management. It is also one of the first valve manufacturers in China that have passed the ISO 9001, ISO 14001 and OHSAS 18001 certifications. Over the past years, it has been awarded national TS permit and U. S. API certificates for both the company and its products. Bohai Valve now is a member of the supply network for State Grid Corporation's power plants, a member listed in the supply networks of China's other four biggest power companies, a company member of China Engineering Construction Industry Association, and the largest supplier of hydropower valves in China.
We maintain our devotion to innovation and keep learning to gain creative ideas and capabilities, transforming our status from a traditional manufacturer to a tech-based enterprise and developing world advanced valve products. For this purpose, the group company set up the Valve Technology Research Center and pooled together the nation's leading experts and engineers so as to provide the most professional solutions with respect to product development, design, manufacturing and testing.
