Our company is the professional manufacture of Butterfly Valve. It is including Wafer Type Butterfly Valve, Soft SealeButterflyValve, Flange Butterfly Valve, and API Butterfly Valve, etc. Zhejiang hangda valve Co., Ltd is one of the modern high and new technological enterprises collecting researching\producing and trading. It is including Hangda valve and Kunshan Kunfa valve branches
Hydraulic Control Slow Closing Non-return Butterfly Valve, Normally named as Counterweight Butterfly Valve is one type of Advanced Products used for management on Controlling Equipments. They are widely used into the area of entrance of Turbine in Hydraulic Power Station, or installed in the pump exit of irrigation, electric and water treatment areas which can replace the functions of Gate valve and Check Valve.
When such product of Hydraulic Counterweight Butterfly Valve is operated, this valve is matched together with main pipeline systems, based on the principle of water pass procedures, through the pre-set on/off procedures, effectively derived the water hammer through the pipeline to realize the flow cut-off and ensure a safety or protection function onto such systems.
Hydraulic Control Slow Closing Non-return Butterfly Valve(Counterweight Butterfly Valve) from rechon vango valves are with features of small flow co-efficiency, high automatic, complete functions or devices, reliable performance which is one new high auto-tech. Energy saving products designed and produced based on domestic/overseas similar areas covering valve, hydraulic and electric industries. With profound knowledge in such products, we rechon vango valve can also welcome customers' OEM order upon request to meet different areas requirement.
Counterweight Butterfly Valves are with following features
1. This Type of Valve of Counterweight Butterfly Valve Can replace the function of Gate Valve or Check Valve from entrance of water pump, with a integral parts of Mechanical, electric and hydraulic a uni-body which can reduce the landing area and base investment etc.
2. With complete function of Both Electric and Hydraulic, there is no need to equip other devices which can be used as a separate system to debug and control at site, this valve can also be services as one unit of system for DCS, managed by central computer through the I/O to realize the united-operation by the water pump, turbine, bypass valve and other pipeline equipments, moreover, this kind of valve is also equipped with handwheel which can ensure that the valve can be operated even without electric power to meet a special debug and controlling requirements under a special work condition.
3. With features of good performance controlling and Wide range of adjustment, rechon vango hydraulic Counterweight Butterfly Valve are with many regulators inside of the Hydrau-electric system which can on/off the system set conforming to different pipelines' requirements, by this way, not only make the valve meet the requirement of on/off condition, further ensuring the valve can (only) be opened at the pre-set time and angle, closed at the pre-set separately and slowing 2ND stage. To realize the valve off without power, effectively eliminated the water hammer and prevent the accidents caused between water pump and turbine, reduce the pressure fluctuation of pipe-network, ensuring a safety and reliable operation of system equipment
4. Main Sealing is with Secondary sealing of Triple-eccentric or double-eccentric sealing structure which is easy on/off and reliable in sealing. Further more; There is an extra enlarged eccentric structure to ensure the Hydraulic Counterweight butterfly valve is with perfect self-sealing function. Small and MID-sized butterfly discs are designed with streamline plate structure, while the big sized discs are with double plated ucture with small crush, smooth flow, valve co-efficiency is within 0.1~0.6 which is more smaller
Hangda valve Co., Ltd is one of the modern high and new technological enterprises collecting researching\producing and trading. It is including Hangda valve and Kunshan Kunfa valve branches. The headquarter is located in Dongou Industrial Zone, Oubei Town, Wenzhou City which named the hometown of pumps and valves in China; Kunshan Kunfa valve is located in the beautiful city called Kunshan that is economic development, technology leading.
For many years, due to the continuous efforts, we are in the process of development gradually formed gate valve, globe valve, check valve, ball valve, butterfly valve, filter, several major products as the leading valve product development system, and constantly develop new products. Product maintenance of large diameter reaches DN2000mm (80 "); High working pressure PN42MPa (class2500); Using the temperature -196 ° C ~600 ° C. The products are mainly using material of carbon steel, alloy steel, stainless steel and special materials. And it is also designed and made according to the users ' special requirements.
Quality is the life! In order to better ensure product quality, the company has established a perfect quality assurance system. Strict testing projects have spectral analysis\penetration testing, \tensile testing\ impact testing\ fire test\ low temperature, \ vacuum testing\ radiographic inspection\ quality nitrogen leak\etc. And we have got the certificates API 6D\DNV 9001\CE\API 607\TS etc.
Our management has already reached the standards of the advanced enterprises of developed countries. It has been closely following strong enterprise in the world., From its found, always adhere to the "based on the standardized management, guided by market demand, to ensure the quality of survival, to customer satisfaction for the purpose, to promote development through product innovation" experience program, and "people-oriented, creating a win-win" management philosophy, recruit more capable personnel conscience, advocating humanistic management, for all kinds of talents to create a good space for development.
