Electromagnetic directional valve is the use of low carbon boron steel valve core material, machining error in 0. 003mm- 0. Between 005 mm. Oil mouth logo and brand label characters that week, neat and smart, and clear. 。 Marine valve 1, judging by appearance: the electromagnetic directional valve with good quality, the body appearance in general is relatively flat, no sand hole, etc. , the body edge chamfer precision and meticulous. Q: how to judge the quality of the electromagnetic directional valve? A: electromagnetic directional valve brand on the market is numerous, low grade of unfair, for consumers, although imported brand products is good, but the price, how to pull out from domestic brands for cost-effective electromagnetic directional valve became a difficult problem. 2, the valve core: electromagnetic directional valve is a valve core shut device, electromagnetic directional valve is a direct vote on the performance of use fixed number of year varies of survival. Below the author that is, from the appearance of the electromagnetic directional valve, to do things, valve core, the respect such as electric magnet for simple judgment electromagnetic directional valve quality stand or fall, give you a reference. 3, solenoid directional valve to the valve body of roughness, roundness, high work degree requirements, sealing groove to smooth, roundness is good. If put in the body, a valve core vertical suspended in the air, the body of high precision will stay fixed in the valve body, valve core is generally directly fall out of poor precision. Generally selected high quality electromagnetic directional valve of high hardness, high wear resistance of metal materials, and has a very strict requirements on machining precision, to ensure that the electromagnetic directional valve can secure work under high pressure.
