Recently, the same model of hydraulic valve spool, has higher precision and stronger sensitivity than its peers. This is a good question. I smiled and said you may not have a comprehensive understanding of hydraulic valve. For all types of hydraulic valve spools, is subject to strict quality control. Under the condition of ensuring that the spool is suitable for the service conditions, we will select the most appropriate tool steel 40Cr, Cr12MoV, 12CrNi3A, 18crniwa and GCr15, etc according to the customer's parameter requirements and service scenarios. 6 major processing processes and 6 major parameters are used. This technology has led the industry, we are not satisfied with these static data, but also need dynamic spool. Since the valve spool needs to move in the valve body, the clearance between the valve spool and the valve body should not only ensure good sealing, but also ensure small movement resistance. Therefore, the matching clearance between the valve spool and the valve body is the top priority affecting the use of the valve spool. The following are the tolerances and matching clearance dimensions of the valve spool and the valve body produced in large quantities by in the actual production process Diameter Valve body tolerance Spool tolerance Minimum clearance Maximum clearance 6mm 0.006mm 0.004mm 0.0025mm 0.0125mm 6-12mm 0.0075mm 0.005mm 0.0050mm 0.0175mm 12-20mm 0.01mm 0.006mm 0.0050mm 0.0233mm 20-25mm 0.0125mm 0.0075mm 0.0125mm 0.0325mm When the reciprocating or rotary valve body is matched with the valve spool, we generally use the minimum clearance, but the specific processing parameters should also be determined according to the customer's parameter requirements and use scenarios, so as to ensure that the hydraulic valve does not have any leakage, valve stuck and other unexpected working conditions. During the processing and manufacturing of valve spool, also strictly considers the following aspects, and will check and test each valve spool when necessary, so as to ensure the high quality and reliability of valve spool. Hydraulic power on hydraulic spool Pressure and flow characteristics of hydraulic valve spool Flow coefficient of hydraulic valve spool Leakage of hydraulic valve spool Stability of hydraulic valve spool Vibration of hydraulic valve spool Cavitation of hydraulic valve spool After listening, they admired rigid attitude and trusted the quality of hydraulic valve more. Using hydraulic valve is reassuring, so has always been their preferred hydraulic valve supplier in . hydraulic valve sticks to itself and high quality control.
