Application
The valves provideexcellent services in industries, where ammonia is used, produced ordischarged. These industries include chemical, steel, power, waste water,fertiliser, textile, fiber, leather, plastic, dye and pharmaceutical, etc.
Feature
Zero Leakage isensured.
a、Primary seal——bellows assembly
It’sa fully enclosure type structure to avoid direct contact with the fluid beingtransmitted. So it could offer maximum service life, maintenance free, andreduce the operating cost.
b、Secondary seal——nonmetallic packing material
The gland packing, stuffed withflexible graphite material, served as an extra protection to preven fromleaking, particularly at high temperature
applications.
c、Position limit
Positionlimit on upper stem provides effective protection from flexible bellowsvariability, to ensure safe use of the valve.
Stem, bellows protection device
a、Anti-rotation block
Preventlateral movement of bellows, to ensure maximum service life of bellows
b、Packing sleeve
Forpacking compression, in order to achieve a better sealing performance
State-of –the- art engineering
a、Surfacing, grinding of the valve, seat
Discmaterial is corrosion-resistant stainless steel or alloy steel. Disc is welded tothe lower end of the stem by plasma transferred arc (PTA) process and is finelapped, ensuring perfect sealing of the contact surfaces between disc and valvebody.
b、Hinged connection
Hingedconnection between disc and stem has increased sealing of the connectingfurfaces and thus zero emissions are guaranteed.
c、Uniquechannel design
The computersimulated valve chamber design offers very low flow resistance. The flow ratecould be increased by 10-15% as compared with valves of similar size.
德国汉克（HANK）进口阀门成立于1852年创建于门兴格拉德巴赫（Monchengladbach）是位于德国北莱茵-威斯特法伦州首府杜塞尔多夫市以西的一座城市。于19世纪50年代初德国经济快速发展，由于德国能源短缺，政府在节能方面加大力度，因此HANK(Trouble Less valve没有故障的阀门)公司成立。汉克阀门是以生产高品质、先进的阀门、测量及控制系统而享誉全球的跨国性生产企业，在全球几十个国家拥有子公司及分支机构，公司产品涉及用途：石油、化工、电力、冶金、制药、食品、水处理、市政给排水、天然气、造纸、电子工业、楼宇、机械设备配套等领域。
GERMANY HANK VALVE LIMITED is founded on 1852 in Monchengladbach,which is located at one city in North Rhine in Germany, which is the west of Nordrhein-Westfalen. At the beginning of 1850s, as the rapid development of economic and the shortages of energy in Germany , the government had been in saving energy aspect. On this occasion, HANK Valve (Trouble Less Valve) was established.Hank valve is the world-famous transnational production enterprise,which produces high quality and advanced valve, measurement and control system, and which has its divisions and branches in dozens of countries in the global. The company products user involves the petroleum, the chemical industry, the electric power, the metallurgy, the drugs manufacture, food, the water treatment, the municipal administration to give draining water, the natural gas, the papermaking, the electronics industry, the building, the mechanical device necessary ect..
德国汉克（HANK）阀门的价值理念概括为：责任－远见－创新。我们因自身的责任感、远见及专注于创造前所未有的解决方案和理念，而成为的阀门制造商。
The conclusion of the valve concept in German Hank valve is resposibility,foresight,innovation. For ourselves resposibility, foresight and focusing on creating unprecendented solution and concept,our company has become the lead of valve manufacturer in the global.
