Valve product service concerns
In today's valve market, valve quality and price are two of the first things most businesses consider, with 79.8% of users putting quality first and 5.8% of users paying the price. However, after-sales service valve products as a marketing management of the key links in many industries has been widely used. Valve industry is no exception. Although still not perfect, but the customer has put forward requirements for this factor.
After-sales service includes "three guarantees", free installation, technical guidance and regular visits. State-owned and private enterprises most want after-sales service includes the content of the "Three Guarantees" commitment; private enterprises and joint ventures most want to be able to do after-sales service free installation; collective, private and foreign enterprises hope to provide after-sales service technical guidance; State-owned and joint ventures Hope that after-sales service can visit regularly.
As the "Three Guarantees" commitment, regular visits and technical guidance is optimistic about the majority of the industry after-sales service (free installation of many companies do not force), so the valve manufacturer should focus on user needs, providing quality after-sales service to eliminate users Concerned about the products that have been received and the companies themselves have already sold.
Design, test standard application problems
Valve design and development of our products generally low level of another important factor is the valve standard application. Domestic valve standards in the field of application is more chaotic. Many valve companies, did not establish a complete standardization system. From the earliest GB (GB) system, and later to API standards, ISO, BS and other standards are also used. In general, the domestic valve standard system lags behind, and lags behind in the standard use. For example, BS EN ISO 10497: 2004 "Valve Test - Fire Test Technical Requirements" has replaced BS6755 · 2, but many companies are still using BS6755 · 2, and some enterprises are still looking for BS6755 · 2. The use of such a serious standard hysteresis, leading to the valve industry design, the relative lag of the overall level of testing.
At present, in addition to the ISO standard, the most influential standard valve system in the world is the ASME, API, MSS and AWWA standards in the United States, the DIN EN standard in Germany, the JIS standard in Japan, the BS EN standard in the UK, and the FN EN standard. China's valve companies to establish a complete standard system, pay attention to the latest changes in standards, the use of leading standards at home and abroad, is to improve and solve the worries of the standard application of the key.
