Mini Pressure Valve DN20

Basic Info.Model NO.H42F-16L DN20SizeDN20TrademarkafsSpecificationDN20OriginShanghai, ChinaProduct DescriptionProduct Description Action of minimum pressure valve for screw compressor:1. The role of the minimum pressure valve is to buffer. When the machine is discharged into the atmosphere at the moment of loading, we assume that the large pressure difference generated before and after separation inside the machine will be added to the separator, causing damage to the separator core.2, machine oil lubrication is carried out by the pressure difference of the machine itself, without additional oil pump assistance, when the machine is in no-load state, still need a certain pressure to maintain the oil cycle, so the inlet valve is relatively closed, and the minimum pressure valve to prevent pressure leakage, so as to ensure the oil cycle.3. The minimum pressure valve mainly plays the role of establishing the internal pressure of the unit, promoting the lubricating oil circulation and meeting the working pressure of the load reducing valve.4. The minimum pressure valve also ACTS as a one-way valve to prevent the back flow of compressed air from the air storage tank to the air compressor during the unloading operation of the unit. Components:The minimum pressure valve is composed of valve body, valve core, adjusting nut, spring and sealing element. Product features:1. Applicable to oil injection screw air compressor;2, the minimum pressure valve in the check function, seals for FKM or PTFE, check sensitive, reliable seal;3, the minimum pressure valve spring through the strengthening treatment, not easy to deformation, fatigue, open pressure stability;4. Diversified installation and connection methods, convenient installation and maintenance. Technical DateMain parts materialPart nameValve bodyGasketO - ringBig springSmall springMaterialsZL101-T6PTFEFKM50CrVASUS304Main diameter Nominal diameterinlet connecteddimensionh1(inlet center height)(outlet connecteddimension)h2(outlet centerheight)d0throat diameterHtotal height(delivery max)m3/minDN202-Φ8.5X64602-Φ8.5X6450Φ201103Specification   TypeH42F-16LNominal pressure1.6MPaNominal diameterDN20Suitable temperature-20/+120ºC Suitable medium(Air)Press a declaration of surrender>>Design manufacture According to GB/T 12243-2005.>>Connecting dimension and ste pressure may be according to user's requestSamples ShowShanghai international compressor and equipment exhibitionAbout Us Shanghai AFS Valve Manufacturing Co., Ltd.  was founded in the early 1970s, specializing in the production of various types of valves, involved in a variety of fields.The company from the early ninety s, form a complete set of air compressor valve involved after decades of development, the main production of various kinds of compressor valve, pressure valve, temperature control valve, the suction valve and so on, at the same time also involves medical breathing machine, cold media series, power plant, oxygen plant, rail transportation, aerospace equipment, valve in the field of chemical industry and so on, successively with more than 60 famous air compressor manufacturer cooperation, such as ingersollRand, Atlas, Fusheng, CompAir, Sullair, Hitachi....We uphold the "Credit First, Customer Uppermost" purpose, committed to the production of high quality, in line with customer demand products.At the same time to provide a variety of users with a full range of fluid and gas system solutions.PartnersCertificates Frequently asked questions Q: what kind of express do you send?  A:  The normal situation is DHL, if you have other needs, you can contact our salesman. Q: how long is your delivery time?  A: Normally, the relief valve takes 7 days and the other valves take 45 days. Q: is it possible to customize the valve?  A: Yes, please contact our salesman for specific size and specification.   If you have another question, pls feel free to contact us as below:   Shanghai AFS Valve Manufacturing Co., Ltd.     Web site:  http://afsvalve.en.made-in-china.com
