Bellows Seal Globe Valves and Gate Valves For Steam System Exported to Philippines

 Totally 107Ppcs of bellows seal valves exported to Philippines for thermal oil system and steam system. There are BW ends PN40 bellows seal Y type globe valves, flanged ends 300lbs Y type globe valve, 300lbs flanged ends bellows seal straight type globe valve and forged steel 300lbs flanged ends bellows seal gate valves etc.

The bellows seal valves use bellows and packing to achieve double seal to ensure excellent stem seal in critical applications such as thermal oil system in dyeing industry, steam system in power industry and poisonous medium like chlorine in chemial industry etc.

The body materials of bellows seal valves can be forged steel like A105, cast steel like WCB, GS-C25, or WC6, WC9 for high temperature applications.


After strict inspection and test, the bellows seal gate valves, bellows seal globe valves with carbon steel body  are painted well to be corrosion resistant.

The bonds between PSA(Pressure Swing Adsorption) and High Performance Butterfly Valve

图片
  High performance butterfly valves ： Generally refers to  double eccentric butterfly valve  and  triple eccentric butterfly valve ,due to their excellent working performance and high sealing ability (compared with concentric butterfly valve) are widely used in petrochemical,power plants,metallurgy,civil heating fields.Eccentric butterfly valves have the good working performacne to meeting sever and strict requirements in many different industries.Today, we are going to introduce the application of eccentric butterfly valve in air separation for making oxygen,hydrogen,CO etc. At present,the mature air separation system is PSA(Pressure Swing Adsorption),it need certain number of programmed valves (valve parts usually double or triple eccentric butterfly valve) in its pipeline system to control and adjust the medium. FEIDA  double (and tripple) eccentric butterfly valve are widely used in this kind of PSA system due to the valves' excellent features: 1-Long service life,on-off 1 mill

Hardening method of metal hard sealed ball valve balls and valve seats

  At present, the commonly used hardening processes for the surface of  metal hard sealed ball valves  mainly include the following: (1) Surface welding (or spray welding) of hard alloy on the sphere can achieve a hardness of over 40HRC. The process of surface welding of hard alloy on the sphere is complex, with low production efficiency, and large area welding can easily cause deformation of the parts. Currently, there is relatively little use of surface hardening technology on the sphere. (2) The surface of the sphere is plated with hard chromium, with a hardness of 60-65HRC and a thickness of 0.07-0.10ram. The chromium plating layer has high hardness, wear resistance, corrosion resistance, and can maintain surface brightness for a long time. The process is relatively simple and the cost is relatively low. However, the hardness of the hard chromium coating will rapidly decrease as the temperature increases due to the release of internal stress, and its working temperature cannot exce

Introduction to the Function, Principle, and Characteristics of Globe Valves

  Globe valves   are used to cut off the flow of media, and are suitable for situations that require frequent opening. The sealing parts of a globe valve are the valve disc and valve seat. In order to ensure a tight closing of the globe valve, the mating surface of the valve disc and valve seat should be ground or a gasket should be used. The sealing surface can also be embedded with corrosion-resistant and wear-resistant materials such as bronze and stainless steel.The valve disc and valve stem of the globe valve are connected in a movable manner to ensure a tight fit between the valve disc and valve stem. The lifting and lowering of the valve disc of a globe valve is generally controlled by the valve stem. The upper part of the valve stem is a handwheel, and the middle part is a threaded and packing sealing section. The function of the packing is to prevent the internal medium of the valve body from leaking along the valve stem. The function of a shut-off valve 1、 The main function o
