Adjust the pneumatic valve 'type'

as a buyer, my main job is to do the daily analysis and price negotiations, to ensure that the procurement of supplies, reasonable price, strive for the optimal price, the lowest total cost, and the work often encounter all kinds of situation, such as the recently is involved in a 'type' daily drama.
this 'type' play the leading role is a pneumatic valve adjustment.
recently, maoming petrochemical company refinery division a renewal projects need to purchase a batch of regulating pneumatic valve, after a series of preliminary work MiLuoJinGu suppliers have identified. The supplier is a Japanese joint venture professional background of regulating pneumatic valve plant, according to the previous purchasing experience, their price is not cheap.
in recent one or two years, adjust the pneumatic valve manufacturer competition is fierce, especially in recent period of time, up to an end, some manufacturers in order to 'impulse', to win orders at, in the form of price war. 'But guess cannot serve as the basis for pricing. The price is reasonable must use specific data to prove. So I immediately set about price analysis. According to adjust the parameters of the pneumatic valve, model and configuration, I from the related system in the history of a large number of similar materials purchasing information to be obtained, through the comparison and analysis, item by item, filtering, basically found out the price details. Sure enough, manufacturers offer really is relatively low, not much space.
suddenly, I felt relaxed. This contract is simple, convenient, good! But have a bit disappointed, negotiations as both sides battle, haven't I sponsored and assault, a white flag to the other party is in a hurry, is really boring!
did not demand a space? I'm a little don't lose heart. Over and over again to check specifications, manufacturers offer, history and purchasing information. Yi? This same number for the Louis vuitton - C regulating pneumatic valve is a bit suspicious! The regulating pneumatic valve is proposed to choose supplier for the yuan, is involved in competitive price with the highest of all suppliers! And several other units are the lowest. It is normal? Is it price strategy or have other problems? Must find out! I'll dig out specification carefully look at it. Use the unit of the specifications of the technical personnel's signature in the book 'regulating pneumatic valve type' described as 'VAC - S”。 真空吸尘器, S？ This is a single-seat regulating pneumatic valve? With my understanding of the supplier product model, it is as if the Angle of the pneumatic valve type? But we are on e-commerce in single-seat regulating pneumatic valve to make an inquiry, and analysis of other supplier's model and quotation should be single-seat pneumatic valve adjustment. Is the supplier made a mistake? Or they think the scene situation Angle of pneumatic valve is more suitable? This can involve the use of technology and the price of the business problems, ambiguity can not!
I contact with the unit using the first time, each other reply to me, the original site is the Angle of the pneumatic valve, the change of Angle of pneumatic valve is not wrong. Contact with the supplier again, I put my doubt, other supplier selection with him said, each other very surprised, also very responsibly said. 'we will dock with the unit using again, ask them to the scene of the actual surveying and mapping, must ensure correct selection! '
in the afternoon, vendors call:' we repeatedly confirmed, according to the field of surveying and mapping results, really should choose single-seat regulating pneumatic valve! '
, the scene of the old pneumatic valve adjustment, is a very old' Angle of pneumatic valve ', is the left into the right out of the horizontal Angle of pneumatic valve, and the left into the traditional meaning of right-angle angles of pneumatic valve. The old 'Angle of pneumatic valve is closer to the single-seat pneumatic valve adjustment. If the selected Angle of pneumatic valve, then there will be problems in installation and use. With the specifications of the single-seat regulating pneumatic valve price is much lower than the Angle of the pneumatic valve. I had sufficient negotiation with the supplier again, the other party agreed to the station to adjust the price of the pneumatic valve changed from dollars to yuan.
at this point, the regulating pneumatic valve variable 'type' the play ended. Many, many. This kind of change is the core of 'ascension'. This kind of change, never end.
